what is the function of helper t cells?  cytotoxic t cells? regulatory cells?
The regulatory T cells (Tregs pronunciation: /ËtiËrÉÉ¡/), formerly known as suppressor T cells, are a subpopulation of T cells which modulate the immune system, maintain tolerance to self-antigens, and prevent autoimmune disease.
The function of cytotoxic T cells, also called killer T cells or cytotoxic T lymphocytes, is to protect the body from disease and infection. They do so by killing diseased cells. T cells are white blood cells that are part are the body's immune system. White blood cells defend your body against disease, cancer, infections and foreign substances.

The difference between Helper T cells and Cytotoxic cells is that the Helper T Cells have no cytotoxic or phagocytic activity. In other words, they cannot kill infected host cells (also known as somatic cells) or pathogens, and without other immune cells they would usually be considered useless against an infection.
