T cells are grouped into a series of subsets based on their function. CD4 and CD8 T cells are selected in the thymus, but undergo further differentiation in the periphery to specialized cells which have different functions. T cell subsets were initially defined by function, but also have associated gene or protein expression patterns.

The sub populations of T cells with functional difference can be identified by means of surface markers (CD markers) or antigens. Approximately 60 – 65% of mature T cells that leave the thymus display CDn”, CD3+, CD4+ and CDS~ markers on their surface and are generally referred as CD4 cells or TH cells or T helper cells.
There are different types of cells in the human body which make up the tissues and organs. A Cell is the basic unit of our life. You can read more about the basic types of cells in living beings. It decides the type, nature and also the functions of the tissues.
T cells come in many types with specific functions, including: Helper T cells direct the immune system. In a rather lengthy process, helper T cells release cytokines. Cytokines stimulate B cells to form plasma cells. Plasma cells form antibodies, which stimulate the production of two other types of T cells: cytotoxic T cells and suppressor T cells.
T cells are central to the cell-mediated immune response. There are many different types of T cells, all derived from same lymphoid stem cell. T cell function, lineage and the T cell receptor are discussed, along with markers and antibodies used to define them.
Generally we classify T cells into two types only- T helper cells(Th cells) and T cytotoxic cells(Tc cells). But the 3 type system includes Tc,Th and T suppressor cells. In reality, T cells have other types too. I will brief them : * Cytotoxic T l...

Not only do T cells directly destroy pathogens, but they regulate nearly all other types of the adaptive immune response as well, as evidenced by the functions of the T cell types, their surface markers, the cells they work on, and the types of pathogens they work against (see Table 5).
