Study Notes
Sensitization
- In the area where the pathogen is located, macrophages actively absorb Mycobacterium tuberculosis (MBT) through phagocytosis, leading to their destruction and death.
- Specific antigens of MBT, including CFP10 and ESAT6 proteins, which determine the pathogen's virulence properties, are presented on the surface of the macrophage cell membrane.
- These antigens are presented to T-lymphocytes, allowing them to recognize and respond to the infection.
- Macrophages secrete anti-inflammatory cytokines, specifically interleukins, which attract T-lymphocytes to the site of infection.
- T-lymphocytes read information about antigens from the macrophage membrane and differentiate into memory cells, allowing them to retain immune memory and respond to future infections.
