Antibodies, Killer T cells, and Antigens play essential roles in triggering the body's defenses against specific pathogens.
Antibodies trigger the body's defenses against specific pathogens by recognizing and binding to the antigens of the pathogens, marking them for destruction by other immune cells such as phagocytes or killer T cells. These antibodies are produced by white blood cells called B cells and are a crucial part of the adaptive immune response.
Killer T cells, on the other hand, directly attack and kill infected or cancerous cells that display specific antigens on their surface. These T cells play a vital role in eliminating cells that pose a threat to the body's health.
Antigens are molecules that trigger an immune response when they are recognized as foreign by the body. They can be proteins, sugars, or other substances that antibodies or immune cells like T cells can bind to, initiating the immune defense mechanism.
