Based on this subreddit’s own stated rules:

r/hantavirus Rules
1. Conspiracy theories might get you banned
Please stick to the facts. If you’re not sure please say so. Don’t just make stuff up. Ok to express fears. Don’t be an alarmist!
2. Respect others and be civil
3. No memes
4. No spam

I made a post that cited peer-reviewed sources and clearly framed the topic as a possible mechanism and potential treatment pathway, not a confirmed therapy, not medical advice, and not speculation without evidence.

That post was removed by a moderator who didn’t even attach their name or provide a clear explanation.

So I’m trying to understand:

How does citing published research violate “stick to the facts”?
How does explicitly stating uncertainty fall under “making stuff up” or “alarmism”?
And how does removing sourced discussion without explanation align with transparency or good moderation?

If discussion of emerging or mechanistic research is not allowed here, that should be clearly stated. But removing sourced, clearly qualified content while citing “rules” that emphasize factual discussion is inconsistent at best.

More importantly, suppressing discussion of possible treatment pathways even when clearly labeled as exploratory and backed by published research is not helpful and can be actively counterproductive. Open, informed discussion is how people learn, evaluate risk, and understand what is and isn’t established science.

I’m open to revising the post to meet guidelines, but that requires clarity on what rule was actually violated.

Right now, this looks less like moderation and more like suppression of discussion that falls outside a narrow comfort zone.

More information, properly sourced and clearly framed, should be encouraged, not removed without explanation.

Hantavirus doesn’t usually kill people because the virus “eats the lungs” the way Hollywood viruses do. What actually happens is more disturbing and more biologically interesting.

The virus primarily infects endothelial cells, the thin cells lining blood vessels and capillaries. In severe hantavirus pulmonary syndrome (HPS), those endothelial cells become dysregulated and hyper-permeable. The body’s own signaling systems start malfunctioning. Fluid leaks out of blood vessels and floods into the lungs. Patients can go from fever and body aches to drowning in their own pulmonary edema within hours.

A huge part of this process appears tied to VEGF signaling and the mTOR pathway.

Researchers found that pathogenic hantaviruses, especially Andes virus, sensitize endothelial cells to VEGF (vascular endothelial growth factor), dramatically increasing vascular leak. The infected cells become enlarged, dysfunctional, and excessively permeable.

This is where rapamycin becomes interesting.

Rapamycin is an mTOR inhibitor already used clinically in transplant medicine and other settings. Multiple hantavirus studies found that rapamycin reduced the abnormal permeability response in infected endothelial cells and blocked giant-cell formation associated with mTOR activation.

In simple terms: it appears to calm down the runaway signaling cascade that contributes to capillary leak and pulmonary edema.

One paper specifically concluded:

> “the ability of VEGF-C and rapamycin to normalize LEC responses suggests a potential therapeutic approach for reducing pulmonary edema and the severity of HPS following ANDV infection.”

Source: https://pmc.ncbi.nlm.nih.gov/articles/PMC3421700/

That does NOT mean rapamycin is a proven frontline treatment today.

These findings are largely mechanistic and experimental, not large-scale human clinical trial evidence. Rapamycin also suppresses parts of the immune system, which could potentially help or hurt depending on timing, dosage, and disease stage.

But the research points toward something important:

Hantavirus may be less about direct viral destruction and more about catastrophic endothelial dysfunction and vascular leak.

If that’s true, then stabilizing endothelial signaling early before the lungs flood could matter just as much as attacking the virus itself.

And that shifts the conversation from:

“How do we kill the virus?” to “How do we stop the body from turning its own blood vessels into sieves?”

Censoring peer-reviewed discussion helps no one
