Web3 ian. 2024 · Lysosomal membrane permeabilization or full rupture of lysosomes is a common and severe stress condition that is relevant for degenerative disease, infection and cancer. If damage is limited, cells can repair lysosomes by means of the endosomal sorting complex required for transport (ESCRT) machiner … WebLysosomes digest bacteria by forming vesicles filled with digestive enzymes. If any bacteria or antigen enter the cell, the plasma membrane gets pinched off and forms a closed vesicle, transported to the Golgi network and fuses with lysosomes having hydrolytic enzymes. After enzymatic digestion, the undigested material is stored in a vacuole ...
WebDespite the fact that these phagocytes are usually very effective in internalizing and clearing most of the bacteria, M. tuberculosis H(37)Rv has evolved a number of very effective survival strategies, including: (a) the inhibition of phagosome-lysosome fusion; (b) the inhibition of phagosome acidification; (c) the recruitment and retention of ...
