Video: How T Lymphocytes Recognize Antigens-Merck ...
T cells (T lymphocytes), as part of the immune surveillance system, must be able to recognize substances that do not belong to the body (foreign antigens). However, they cannot directly recognize an antigen. T…

T cells can only recognise antigens when they are displayed on cell surfaces. This is carried out by Antigen-presenting cells (APCs) , the most important of which are dendritic cells, B cells, and macrophages.…

Abstract Adaptive immune recognition is mediated by specific interactions between heterodimeric T cell receptors (TCRs) and their cognate peptide-MHC (pMHC) ligands, and the methods to accurately predict TCR:p…
