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.

NO-induced apoptosis, but not TNF-α–dependent apoptosis, correlates with the induction of p53 and Bax. Materials and methods Reagents LPS was obtained from Sigma Chemical (St Louis, MO). Webapoptosis and necrosis—can contribute to hepatocyte death. In apoptosis, the affected cell actively participates in the cell death process, whereas in necrosis the cell death occurs in response to adverse conditions in the cell’s environment.
