Out of interest, I Googled the connection between hantavirus and stab1 (Bex).
HTNV (Hantaan virus subspecies) causes a strong inflammatory response in humans, but in rodents, the immune response later shuts down into a protective M2 state. STAB1 is a marker for this anti-inflammatory M2 phase (if I understood that table correctly).
I don’t expect it to be the answer to Hantaan, but perhaps in the distant future for suppressing inflammatory reactions—could it be possible as a combination therapy?
