Did you mean T cell receptor signaling?

GlossaryT cell receptor signaling

process where T cells recognize and respond to antigens

T cell receptor signaling, often abbreviated as TCR signaling, is a crucial process in the immune system where T cells recognize and respond to foreign molecules, such as pathogens. When a T cell receptor binds to an antigen presented by other cells, it triggers a cascade of intracellular events that activate the T cell, enabling it to attack infected cells or coordinate other parts of the immune response. This signaling is essential for the body's ability to detect and fight infections and diseases.
