T Cell Migration refers to the movement of T cells, a type of white blood cell, throughout the body. These cells play a crucial role in the immune system by identifying and attacking pathogens. T cells migrate through the bloodstream and tissues, guided by chemical signals called chemokines, which help them locate areas of infection or inflammation. During migration, T cells can enter lymph nodes, where they interact with other immune cells to enhance their response. This process is essential for mounting an effective immune response and ensuring that T cells reach the sites where they are needed most to combat infections or diseases.
