WebImmunization with the OVA/IL-2 protein after adoptive transfer of OVA-specific T cells maintained the OVA-specific cytotoxicity and cell number of adoptively transferred T cells long term in vivo, while a simple mixture of recombinant OVA (rOVA) and rIL-2 did not. The response was dependent on the injection doses and times of the OVA/IL-2 protein. WebCytotoxicity is a general term that describes the detrimental effects of substances or environmental changes on cell health. Exposure of cells to a cytotoxic stimulus may compromise metabolic activity, inhibit cell growth or division or ultimately produce cell death. 'Necrotic' cell death is a catastrophic cell lysis.
