The discovery by Govaerts of lymphocytes able to kill graft cells in vitro immediately triggered speculation about the molecular mechanism(s) underlying destruction of the targeted cells. Experimental approaches to this question fell into two broad camps: some looked for a fixed, physical property of...
Adapted from “T Cell Activation in Cancer” by BioRender.com (2021). Retrieved from https://app.biorender.com/biorender-templates. By recognizing the target antigen by the TCRs, T cells initiate target cell apoptosis. The main mechanism of killing the target cell by CTL is the release of ...
, the apparent absence of membrane perforation in various examples of lymphocyte-mediated killing, and the observation that perforin alone could not account for apoptosis associated with programmed cell death, suggested that perforin activity represented, at best, only a part of the whole mechanism. ...
2) CD8+ T-cell cytotoxic mechanisms destroying β-cells were limited to perforin and Fas ligand, as double knockouts of these molecules abrogated the ability of T cells to cause diabetes; and 3) individual CD8+ T-cell clones chose their cytotoxic weaponry by a yet unknown mechanism and destro...
(TNF-α)- or TNF-related apoptosis-inducing ligand-mediated apoptotic mechanisms in the pathomechanism is analyzed. The frequency and function of effector cytotoxic cells of natural immunity itself such as natural killer (NK) cells, NKT cells, and γδT cells are also changed both in the ...

This killing process occurs at immune synapses formed between CD8+ cytolytic T cells (CTLs) and target tumor cells, where the T cells release pore-forming perforin and pro-apoptotic protease granzymes2,3. Perforin then creates pores in the tumor cell membrane, allowing the entry of granzymes ...
