Cell-mediated Immune Response

The cell-mediated response can act alone but normally it interacts with antibody immunity to counter the huge range of infectious agents to which animals are exposed in their lives.

Specialised white blood cells - T-cells - recognise and destroy infected host cells.

The specialised T-cells recognise the special signs of infection. They then multiply and become "activated" killer T-cells.

The killer T-cells attach themselves to those infected cells and destroy them.
