“…In addition, at chronically blocked NMJs with either bungarotoxin or curare, the turnover rate of AChRs was also significantly increased with a half-life of hours [32]. Likewise, at neuromuscular diseases such as the autoimmune disease myasthenia gravis or muscles treated with IgG from myasthenia patients, the rate of AChRs degradation was significantly increased, leading to a decrease in AChR density and a reduction in synaptic folds [34,[56][57][58][59]. A recent report also showed that in high-fat diet-induced obese male mice, the turnover rate of AChR significantly increased and the postsynaptic AChR density was considerably reduced, leading to a significant loss of postsynaptic receptor regions [60].…”
