细胞坏死(necrosis):细胞坏死是因病理而产生的被动死亡,如物理性或化学性的损害因子及缺氧与营养不良等均导致细胞坏死。坏死细胞的膜通透性增高,致使细胞肿胀,细胞器变形或肿大,早期核无明显形态学变化,最后细胞破裂。另外坏死的细胞裂解要释放出内含物,...
Apoptosis vs necrosis: glutathione-mediated cell death during rewarm- ing of rat hepatocytes. Biochim Biophys Acta 2005;1740:367-74.Vairetti, M.; Ferrigno, A.; Bertone, R.; Richelmi, P.; Berte, F.; Freitas, I. Apoptosis vs. necrosis: glutathione-mediated cell death during rewarming of ...
There are at least two major types of active or physiological cell death. The most well-known form, apoptosis or Type I, involves early nuclear collapse, condensation of chromatin, generation of nucleosomal ladders, and cell fragmentation with little or no early alteration of lysosomes. It is mo...
We focus on apoptosis, necroptosis, and pyroptosis and on how these processes regulate the immune response. NECROPTOSIS: REGULATED NECROSIS WITH PASSIVE AND ACTIVE PROINFLAMMATORY FUNCTIONS Mechanisms of action and regulation of necroptosis Apoptosis was long thought to be the only regulated cell death ...
aQuantification of cell apoptosis and necrosis by Flow Cytometer. In each panel, the lower right quadrant indicates the apoptotic cells, whereas the upper left shows the necrotic cells. 细胞apoptosis和坏死的量化由流程Cytometer。 在每个盘区,更低的正确的象限表明apoptotic细胞,而左上部展示坏死的细胞。[...
除以上一些抗癌药物之外,研究发现通过肿瘤坏死因子(tumor necrosis factor,TNF)相关的凋亡诱导配体受体(TNF-related apoptosis-inducing ligand receptor,TRAIL-R)靶向抗体,也可清除癌症患者的MDSC。使用激动性TRAIL-R抗体DS-8273a治疗后,包括胰腺癌患者在内的多数受试者外周血以及肿瘤组织内的MDSC数量可减少到正常水平,...

Since the discovery of cell apoptosis, other gene-regulated cell deaths are gradually appreciated, including pyroptosis, ferroptosis, and necroptosis. Necroptosis is, so far, one of the best-characterized regulated necrosis. In response to diverse stimul
gene expression, and protein stability [56,57,58,59,60]. In addition to regulating GPX4 function, ferroptosis agonists also degrade GPX4 via autophagy or the ubiquitin–proteasome system [61,62,63]. Notably, GPX4 regulates cell apoptosis, necrosis, and pyrodeath in addition to ferroptosis [64,...
