How do lysosomes aid in apoptosis
WebThe release of lysosomal hydrolase into the cytoplasm is accompanied by several systems of apoptosis signal transduction, and the imbalance between cell viability and apoptosis … 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].

In this review, we discuss different apoptotic pathways in which plasma membrane and membrane organelles, such as mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and …
WebA lysosome or phagolysosome is able to break down the stuff inside of itself by drastically lowering the pH of its internal environment. Lowering the pH makes the environment inside the phagolysosome makes it very acidic. This is an effective way of killing or neutralizing whatever is inside the phagolysosome so it cannot infect them cell. WebPrior to apoptosis induction, cells showed a diffuse cytosolic immunostaining of Bax (Figure 5a), and no co-localization of Bax with lysosomes was detected after overlay of images (Figures 5a-c). In STS-exposed cells, there was a punctate distribution of Bax that in part co-localized with lysosomes as detected by yellow staining in overlay ...
