In vitro-activated chicken ovalbumin (OVA)-specific OT1 CTLs were confronted with transformed mouse embryonic fibroblasts expressing the OVA peptide (MEC-1/OVA) and the co-stimulatory molecule B7.122,23. In contrast to tumor cells that evolved in vivo, this engineered model lacks natural immune … See more To compare effector function against solid tumor cells, which typically retain resistance to CTL-mediated killing, OT1 CTL were confronted with mouse melanoma B16F10 … See more Across all tested tumor models, sequential or simultaneous contacts by multiple CTL with the same target cell occurred before target cell death … See more To address whether transient perforin pores were associated with structural intracellular damage, B16F10/OVA cells were engineered to express green fluorescent … See more We then addressed whether apoptosis could have been induced by rare deadly CTL hits (“stochastic killing”) or, instead, by sublethal contacts that add up over time (“additive … See more In phase two, the now functional effector CTLs destroy the target cells. This can be done in two ways. These pathways are the cytotoxic protein pathway and the Fas ligand pathway. Apoptosis is the primary mechanism for both of these pathways. One pathway is the cytotoxic protein pathway. In this pathway perforins and granzymes are taken up by the target cell. In this pathway, the perforins facilitate the entry of granule contents into th… port authority of palm beach county
