This defence is innate and can effectively protect you against the most dangerous pathogens. It consists of cells that are deployed in critical places like machine gun nests.

These pieces of pathogens are exposed on the surface of so-called antigen-presenting cells and shown to the cells of specific immunity, which learn to recognise these pieces.
