A few additional treatment possibilities in COVID19 (SARS Cov-2) addressing furin-like cleavage and pyroptosis (caspacin-1 activation of inflammasome NLRP3)

The cytokine storm seen in SARS Cov1 and Cov2 might be due to chronic pyroptosis activation. However, known activators of NLRP3 in SARS-CoV differ from CoV2.  While SARS Cov1 and COVID19 are genetically very similar, the extraordinarily high rate of infectivity of COVID19 is unique. Prepublication research suggests the cause might be a unique furin-like cleavage site on the spike protein of Cov2 that was absent in Cov1.
