T lymphocyte activation

T lymphocyte activation is a key part of your immune response. When a T cell encounters a pathogen or an infected cell, it recognizes specific signals indicating danger. The T cell then interacts with other immune cells and receives additional chemical signals, which "activate" it. Once activated, the T cell multiplies and develops the ability to attack infected cells or help other immune cells. This process ensures your body can efficiently respond to threats, remember pathogens, and protect you from illness.
