Chaperone-mediated autophagy (CMA) is a lysosomal pathway that participates in the degradation of cytosolic proteins. CMA is activated by starvation and in response to stressors that result in protein damage. The selectivity intrinsic to CMA allows for removal of damaged proteins without disturbing nearby functional ones. CMA works in a coordinated manner with other autophagic pathways, which can compensate for each other. Interest in CMA has recently grown because of the connections established between this autophagic pathway and human pathologies. Here we review the unique properties of CMA compared to other autophagic pathways and its relevance in health and disease.
伴侣蛋白介导的自噬(CMA)是一种溶酶体途径,参与细胞质蛋白的降解。CMA 由饥饿和应激反应激活,这些反应会导致蛋白质损伤。CMA 的内在选择性允许去除受损的蛋白质,而不会干扰附近的功能蛋白。CMA 与其他自噬途径协调工作,可以相互补偿。由于这种自噬途径与人类病理学之间建立了联系,最近人们对 CMA 的兴趣有所增加。在这里,我们将比较 CMA 与其他自噬途径的独特特性及其在健康和疾病中的相关性。
