WebIntroduction Autophagy and apoptosis play major roles in determining cellular fate. Accordingly, they participate in development, cellular homeostasis, and both physiological as well as pathological processes. Apoptosis and autophagy are discrete cellular processes that are mediated by distinct groups of regulatory and executioner molecules [1, 2]. WebAmong them, apoptosis is the most common and well-studied type of PCD. In this review, we discuss different apoptotic pathways in which plasma membrane and membrane organelles, such as mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and …
