WebTNF beta is produced by activated lymphocytes and can be cytotoxic to many tumor and other cells. In neutrophils, endothelial cells, and osteoclasts, TNF beta can lead to activation while in many other cell types it can lead to increased expression of MHC and adhesion molecules. TNF pathway signaling implication in disease WebApoptosis can be initiated through one of two pathways. In the intrinsic pathway the cell kills itself because it senses cell stress, while in the extrinsic pathway the cell kills itself because of signals from other cells. …

WebIn contrast to necrosis, apoptosis follows a sequence of events which is triggered by specific signals that instruct the cell to undergo cell death. As such, apoptosis is a fundamental eukaryotic biological process whereby individual cells die by activating their own genetically programmed cell death mechanisms. ... The main cause of apoptosis ... WebApoptosis is the process of programmed cell death (PCD) that may occur in multicellular organisms. [3] Biochemical events lead to characteristic cell changes ( morphology) and death. These changes include blebbing, cell shrinkage, nuclear fragmentation, chromatin condensation, and chromosomal DNA fragmentation.
