3. T regulatory cells/supressor cells (Treg cells/ Ts cells)
4. Memory T cells (Tm cells)
Define Helper T cells (Th cells)
Cells that coordinate the immune response and cell-mediated immunity. These are required to maintain cytotoxic T cell responses.
Define Cytotoxic (Tc cells)
Cells that kill foreign cells, virally infected cells, or cells with new surface antigens.
Define T regulatory cells/ supressor T cells (Treg cells/ Ts cells)
Cells that interfere with development of immune reaction when recognizing antigen: primary role is to modulate the severity of inflammation produced by infection but also play an important role to prevent autoimmunity and may be involved in malignancy.
