T cell theory

T cell theory describes how a specific type of immune cell, called T cells, plays a crucial role in defending the body against infections. T cells are produced in the thymus and identify, attack, and destroy infected or abnormal cells, including some cancer cells. They also help coordinate other parts of the immune system. Essentially, T cells are like special agents that recognize threats through unique markers and respond rapidly to protect health. This theory helps us understand how our immune system targets and eliminates harmful invaders, maintaining overall health.
