T-cell immunity

T-cell immunity is a crucial part of the immune system that helps protect the body from infections. T cells are a type of white blood cell that identify and destroy virus-infected cells, cancer cells, and other threats. They recognize specific markers on invaders, enabling targeted responses. When an infection occurs, T cells become activated and coordinate with other immune cells to eliminate the threat efficiently. They also play a vital role in immune memory, ensuring the body responds faster if the same pathogen appears again. Overall, T cells are essential for controlling infections and maintaining immune defense.
