Helper cells are a certain type of white blood cells (more precisely: T lymphocytes), which play a central role in the Immune system play.
- They recognise pathogens such as viruses or bacteria and activate other defence cells.
- As a result, they control the Defence reaction of the body.
Special feature of HIV:
- HIV mainly affects the so-called T helper cells (CD4 cells).
- If these cells are destroyed by the virus, the immune system weakens.
- The fewer helper cells there are, the more difficult it is for the body to fight off infections or diseases.
