T Cells

T cells are responsible for disease resistance. There are three types of T cells, each with a special purpose.

  1. Helper T cells detect infection and get the other cells of the immune system ready to do battle. Helper T cells also tell B cells to produce antibodies.
  2. Cytotoxic T cells attack virus-infected cells.
  3. Suppressor T cells tell the immune system when the battle with the infectious pathogens is over and to stop fighting.
