These cells produce antibodies at bind to antigens and neutralize them. Each B cell makes one specific type of antibody.

These cells help to get rid of good cells that have already been infected.

specialised cells involved in the detection, phagocytosis and destruction of bacteria and other harmful organisms. In addition, they can also present antigens to T cells and initiate inflammation by releasing molecules (known as cytokines) that activate other cells.

These cells destroy cells that have been infected by invader.

Neutrophils express and release cytokines, which in turn amplify inflammatory reactions by several other cell types. In addition to recruiting and activating other cells of the immune system, neutrophils play a key role in the front-line defense against invading pathogens.
