Supplementation with glutathione, regardless of the commercial form, reduced oxygen consumption and browning intensity when laccase was not present in the grape juice
In addition to this attack, which might be caused by homocysteinylation of the vascular wall proteins by homocysteine and/or its oxidized products (homocysteic acid, homocysteine sulfinic acid, and homocysteine thiolactone), in vitro and in vivo work suggests that reduced homocysteine can inhibit endothelial cell turn-over (Wang et al, 1997) and promote smooth muscle cell proliferation (Lubec et al, 1996b

If SCoV2 is targeting GSH biosynthesis as well as TXNRD1 and GPx1 for proteolytic knockdown, in infected cells, the resulting decreases in these critical antioxidant molecules would contribute to increased oxidative stress, NF-B activation and pro-apoptotic signaling ( these consequences of virus-mediated proteolysis would be taking place in everyone who is actively infected, regardless of their Se status , and would thus be consistent with results suggesting that Se intakes up to several times the minimal dietary requirement are associated with an increase in cure rate from COVID-19 (Figure 2) and the stochastic nature of such molecular interactions
