Virus-specific T cells are a type of immune cell that is targeted towards a specific virus. These T cells play a crucial role in the body's immune response to viral infections by recognizing and attacking virus-infected cells. Virus-specific T cells are able to detect small pieces of viral proteins called antigens on the surface of infected cells, triggering their activation and proliferation. This ultimately leads to the destruction of virus-infected cells and the elimination of the virus from the body. Studying virus-specific T cells is important for understanding how the immune system responds to viral infections and for developing strategies to enhance the body's ability to fight off viruses.
