Mapping the complete host-response
cascade for Hantavirus
There is no FDA-approved antiviral for hantavirus. The current standard of care for severe cases is ECMO and supportive therapy. This 25-node computational cascade maps the full host-response network from viral entry through vascular collapse — identifying 4 repurposable therapeutic intervention points.
The PHYSIM Platform: A deterministic computational physics platform. Governed by strict mathematical laws, the system maps the entire human genome across every known disease to compute biological certainty, not generative probability. AI serves only as our translator — the core analysis is reproducible, auditable, and deterministic.
This does not replace the laboratory — it de-risks before you get there. Instead of screening thousands of candidates blindly, the system narrows the search space to a focused set of computationally validated targets worth testing. Each finding on this page is a possible new discovery — a possible path toward helping patients — that deserves rigorous experimental validation.
From integrin hijacking to vascular collapse
ANDV exploits αVβ3 integrin for cell entry, then systematically disables interferon defenses, triggers cytokine storm, and collapses vascular integrity through the fibrinogen cascade — culminating in DIC-like coagulopathy.
The cascade terminates in disseminated intravascular coagulation (DIC) — the fibrinogen triad (FGA, FGB, FGG) consumes clotting factors faster than the body can replace them.
2 structural insights the analysis surfaced
These findings emerged from the cascade structure and reveal intervention logic that may not be obvious from individual pathway studies.
VEGFA → KDR → CDH5: The Permeability Triad
The analysis identified a 3-node vascular permeability cascade at Tier 3. VEGFA activates KDR (VEGFR-2), which destabilizes CDH5 (VE-Cadherin) — the primary endothelial junction protein.
This is the structural mechanism behind Hantavirus Pulmonary Syndrome (HPS): the lungs flood because the endothelial junctions dissolve.
Fibrinogen Cascade: FGA/FGB/FGG → DIC-Like Coagulopathy
The cascade terminates in the fibrinogen triad — FGA, FGB, FGG — driving a DIC-like consumptive coagulopathy. Fibrin deposition outpaces the body's ability to lyse it, while PLG (plasminogen) activation creates a destructive feedback loop.
This is the mechanism behind the hemorrhagic and thrombotic features of severe Hantavirus Pulmonary Syndrome. The lungs fill with fluid while clotting factors are consumed systemically.
Structural Verification: Hantavirus → Fibrinogen Convergence
To ensure the cascade's convergence on the fibrinogen terminal is not a statistical artifact, we ran a structural proximity intersection against a random protein baseline. A parity score below 0.10 indicates structural convergence beyond noise.
4 intervention points mapped to the cascade
Each therapeutic was identified by its position in the host-response network — targeting a specific tier of the cascade.
Why hantavirus research matters now
Hantavirus is a neglected pathogen with no approved antiviral and limited therapeutic options. Recent outbreaks underscore the urgency.
MV Hondius Cruise Ship — 2026 Andes Hantavirus Outbreak
An active outbreak aboard the MV Hondius in the Antarctic region has resulted in confirmed infections and fatalities. Andes hantavirus (ANDV) is the only hantavirus confirmed to transmit person-to-person — making containment on a vessel extremely difficult.
Zero FDA-Approved Antivirals for Hantavirus
Despite decades of research, there is no FDA-approved antiviral or vaccine for hantavirus. Ribavirin has shown mixed results. The primary survival intervention for severe HPS is ECMO — a machine that oxygenates your blood outside your body — and time.
Why Computational Analysis Matters for Neglected Pathogens
Neglected pathogens receive a fraction of pharma R&D investment. Computational disease analysis can map the full host-response cascade and identify repurposable FDA-approved compounds — without requiring years of wet-lab screening. Every therapeutic target on this page was identified from structure, not trial-and-error.
The Coagulopathy Problem in Hantavirus Pulmonary Syndrome
Severe HPS terminates in DIC-like coagulopathy — the fibrinogen triad (FGA/FGB/FGG) consumes clotting factors while PLG (plasminogen) creates a destructive fibrinolytic loop. Understanding this terminal architecture is critical for designing interventions that interrupt the cascade before organ failure.
