T cell functionality
T cells, also called T lymphocytes, are an integral component of the adaptive immune system which seek out and eliminate foreign particles. Functions of T cells include killing infected host cells, activating other immune cells, producing and releasing immune messengers called cytokines into the body, and regulating the immune response. When T cell functionality is hindered by disease, genetics, or environment, the immune system could be at severe risk.
