Cytotoxic T cells are responsible for identifying and destroying cells that display specific non-cell proteins, such as virus-infected or cancerous cells. This is why they are sometimes called "killer cells". Helper T cells help activate and coordinate other immune system cells, suppressor T cells regulate immune responses, and memory T cells "remember" previously encountered pathogens for a faster response upon future exposure. Macrophages are also immune cells that help engulf and destroy foreign substances.
