Cytotoxicity of cells
Cytotoxicity is the quality of being toxic to cells. Examples of toxic agents are an immune cell or some types of venom, e.g. from the puff adder (Bitis arietans) or brown recluse spider (Loxosceles reclusa). See more Treating cells with the cytotoxic compound can result in a variety of cell fates. The cells may undergo necrosis, in which they lose membrane integrity and die rapidly as a result of cell lysis. The cells can stop actively growing … See more A highly important topic is the prediction of cytotoxicity of chemical compounds based on previous measurements, i.e. in-silico testing. For this purpose many QSAR and virtual screening methods … See more • Antireticular Cytotoxic Serum • Host-pathogen interface • Membrane vesicle trafficking See more • Cytotoxins at the U.S. National Library of Medicine Medical Subject Headings (MeSH) See more Cytotoxicity assays are widely used by the pharmaceutical industry to screen for cytotoxicity in compound libraries. Researchers can either look for cytotoxic compounds, if they are interested in developing a therapeutic that targets rapidly dividing … See more Some chemotherapies contain cytotoxic drugs, whose purpose is interfering with the cell division. These drugs cannot distinguish between normal and malignant cells, but they … See more Antibody-dependent cell-mediated cytotoxicity (ADCC) describes the cell-killing ability of certain lymphocytes, which requires the target cell being marked by an antibody.
