The major recognized function of CTL is in halting virus infections. Earlier, we proposed that CTL might halt virus infections prelytically, by fragmenting viral and cellular nucleic acids, and that in this case, cytolysis per se might be a less important ...
WebMar 5, 2024 · In autocrine function, the same cell that releases the cytokine is the recipient of the signal; in other words, autocrine function is a form of self-stimulation by a cell. In contrast, paracrine function involves the release of cytokines from one cell to other nearby cells, stimulating some response from the recipient cells.
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.
