Cytolytic capacity
Cytolysis, also known as osmotic lysis, occurs when a cell bursts and releases its contents into the extracellular environment due to a great influx of water into the cell, far exceeding the capacity of the cell membrane to contain the extra volume. This is a concern particularly for cells that do not have a tough cell wall … See more Cytolysis can be caused by many factors, from the tonicity of the extracellular fluid to the activity of other cells affecting the structure of the cell membrane. See more Cytolysis is often used as a tool of survival by various cells. While single celled organisms and pathogens use it to repel attack or gain access to new hosts, multicellular … See more In spite of its many uses, it is important for an organism to control when and how cytolysis occurs. Plants have a natural defense mechanism against cytolysis because they contain … See more WebApr 7, 2024 · Taken together, these experiments indicate that even in the complete absence of MHC-I, autologous primary bulk CD8 + T cells have the capacity to reduce HIV-Gag expression in CD4 + T cells in an in vitro model of productive HIV infection, and that this likely occurs in a non-cytolytic manner.
