Web14 mei 2024 · T cells are T lymphocytes that belong to the CD4 + subset. These cells have a number of direct functions, but they get their name from the help they provide to other types of effector cells, such as B cells and cytotoxic T lymphocytes (CTLs). The help consists of secreted cytokines that stimulate the helped cells. Types of Helper T Cells WebIn addition to their immunological properties (eg, homing capacity or effector function), memory T cells can be differentiated using the expression of two markers: CD45RA and CCR7. 12 It has been shown that the expression of these markers and the number of cells in each phenotype remain fairly stable in the same individual but phenotypic …
