Circulating Fe 3+ enters cells with the assistance of transferrin and subsequently converts to Fe 2+ ( 2+ can catalyze the generation of metabolically toxic reactive oxygen species and phospholipid peroxide through the Fenton reaction, leading to cell damage or death (Figure 4)
however, the cleavage sites differed, as evidenced by the generation of distinct S2-derived proteolytic fragments To determine whether these differences in cleavage sites affected spike protein function, we assessed cellcell fusion between S protein-expressing 293 T cells pretreated with each protease and ACE2-expressing VeroE6/TMPRSS2 cells (Fig
