What do antigens stimulate?

Antigens stimulate the immune system to respond by triggering the activation of immune cells, particularly B cells and T cells. When B cells encounter an antigen, they can produce specific antibodies that bind to the antigen, neutralizing it or marking it for destruction. T cells can directly attack infected or abnormal cells or help orchestrate the overall immune response. This stimulation is crucial for the body’s ability to recognize and defend against pathogens.
