WebApr 30, 2012 · Cytolysis An additional mechanism of regulation is the killing of effector T cells or possibly tumor antigen-presenting DCs. Tregs have been shown to exert cytolytic functions by using a variety of mediators, such as granzyme B ( 23, 24 ), the TRAIL pathway ( 25 ), and galectin-1 ( 26 ).
Cytolysis, or osmotic lysis, occurs when a cell bursts due to an osmotic imbalance that has caused excess water to diffuse into the cell. Water can enter the cell by diffusion through the cell membrane or through selective membrane channels called aquaporins, which greatly facilitate the flow of water. It occurs in a hypotonic environment, where water moves into the cell by osmosis and cau… WebMar 2, 2024 · When immune cells are added to adherent target cells, their cytolytic activity causes the adherent cells to round up and detach, consequently reducing CI value.
