WebPhosphatidylcholine (PC) is a choline-containing, zwitterionic phospholipid (structure shown in Figure 1) that constitutes between 30 and 60% of the phospholipid mass of eukaryotic cell membranes. WebApr 14, 2024 · Hsp70.1 has a dual function as a chaperone protein and lysosomal stabilizer. In 2009, we reported that calpain-mediated cleavage of carbonylated Hsp70.1 causes neuronal death by inducing lysosomal rupture in the hippocampal CA1 neurons of monkeys after transient brain ischemia. Recently, we also reported that consecutive injections of …
