T cell responses

T cell responses are a key part of the immune system that help defend the body against viruses, bacteria, and infected cells. Once they detect a threat, T cells activate and coordinate an attack, either by directly destroying infected cells or by signaling other immune cells to respond. They are highly specific, recognizing unique markers on pathogens, which allows for targeted and efficient immunity. This process is crucial for clearing infections and forming immune memory, which helps the body respond more quickly if the same pathogen invades again.
