The cleavage is mediated by furin peptidase at the S1/S2 site of the spike protein, and by transmembrane protease serine 2 (TMPRSS2) at the S2 site within the S2 domain, as shown in human airway cells 10 ( Figure 2 )
In the connection to inflammation, we showed that elevation of pro-inflammatory cytokine IL-6, increased anxiety at the lightdark test, and smaller hippocampal volume characterized at baseline (before any applied stress) those mice that become susceptible after social defeat stress (SDS) with social withdrawal and impaired transcriptomic-wide changes in ventral dentate gyrus, and that administration of LAC promoted behavioral resilience at the SDS paradigm in this susceptible phenotype [27]

[20] [7] This conversion is illustrated by the reduction of peroxides (via the sulfenate as an intermediate): GSH + R 2 O 2 GSOR + ROH GSOR + GSH GSSG + ROH Net reaction: 2 GSH + R 2 O 2 GSSG + 2 ROH (R = H, alkyl) and with free radicals, forming glutathionyl radicals (GS ) that may dimerize to disulfide: GSH + R RH + GS 1/2 GSSG Thiyl radicals (such as glutathionyl radicals) are themselves oxidizing species in biology, with a single-electron reduction potential sufficient for oxidation of nucleic acids, proteins and polyunsaturated lipids
