WebAug 1, 2024 · Cyanotoxins are produced and contained within the cyanobacterial cells (intracellular). The release of these toxins in an algal bloom into the surrounding water occurs mostly during cell death and lysis (i.e., cell rupture) as opposed to continuous excretion from the cyanobacterial cells. WebCytotoxic T cells are very specific. There is a different one for each antigen. A cytotoxic T cell will bind only to cells with an MHC 1 that is presenting the specific antigen that the … ctc store chatham
Microbial Pathogenesis and Virulence Factors Flashcards - Quizlet
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 and dividing (a decrease in cell viability), or the cells can activate a genetic program of controlled cell death (apoptosis). Cells undergoing necrosis typically exhibit rapid swelling, lose membrane integrity, shut down m… WebUptake and action of large clostridial cytotoxins. (1) Toxin binding to cell surface receptors. (2) Endocytosis of the receptor-toxin complex. (3) Membrane insertion and toxin translocation in low pH–endosomes. (4) Activation of the CPD by InsP6-binding, followed by autocatalytic cleavage and (5) release of the glycosyltransferase. WebHow do cytotoxic T cells make holes in foreign cells?
