As part of the immune system, all lymphocytes are designed to ultimately defend the body against pathogens. However, amongst the T-cell variety of lymphocytes there are three further subdivisions/types:

  • Helper T-cells: Act as regulators by producing proteins (lymphokines) that lead to the activation of the immune system, hence indirectly lead to the destruction of pathogens.
  • Killer T-cells: Cytotoxic, hence they directly attack pathogens.
  • Suppressor T-cells: Suppress Helpers and Killers, hence preventing the body from attacking its own tissues.
