Antibodies

Antibodies are proteins produced by the immune system to identify and neutralize foreign substances like viruses and bacteria. Each antibody is specific to a particular pathogen, much like a lock and key. When a foreign invader enters the body, antibodies attach to it, marking it for destruction by other immune cells. They play a critical role in defending against infections and are also used in medical tests and treatments, such as vaccines, which help the body prepare for future encounters with specific pathogens. Understanding antibodies is essential for advancements in immunology and medicine.

    Antibodies are special proteins made by our immune system to help fight off infections. When harmful substances like viruses or bacteria enter the body, antibodies recognize and bind to them, marking them for destruction by other immune cells. Each antibody is specific to a particular invader, much like a key fits a specific lock. This process helps protect the body, and once the body encounters a pathogen, it can remember it, allowing for a quicker response if the same invader appears again. Vaccines work by training the immune system to produce antibodies against certain diseases.
