One Receptor Antigen Directs Development of Two T-Cell Types

Nov 4, 2016 11:05:02 AM / by Stacy Matthews Branch, DVM, PhD posted in Cytotoxic T Cells, Regulatory T Cells, T-cell receptors


T-cell receptors (TCRs) are membrane proteins involved in T-cell activation in the presence of an antigen (invading organism or molecule). Each T cell (cytotoxic T cells, T regulatory cells, etc.) has a unique TCR that recognizes a specific antigen. Triggering TCRs result in a number of events in the immune response including the production of cytokines (cell signals), T-cell development, gaining of specific T cells functions, and more.
