Naive t cells encounter antigen and activate, eventually leaving this compartment as an effector t cell at dendritic cells in lymph tissue (lymph nodes and spleen).
<h3>What is T-cell activation?</h3>
They are a type of white blood cell. T-lymphocytes are the part of the immune system and develop from stem cells in the bone marrow however they develop fully in thymus and leave after maturation. They help in protecting the body from infection and may also help fight cancer. They are also known as T cell and thymocyte.
T-cells get mobilized when they encounter a cell (dendritic cells or B-cells) displaying antigenic peptides bound to its MHC molecule. This MHC-antigen complex activate T-cells receptors and the T-cells start secreting cytokines.
some T-cells become helper T-cells and attract fresh macrophages, neutrophils and other lymphocytes and other cytokines to direct them at the site of action while some T-cell become cytotoxic and track down the virus infected cells.
