T cell-mediated immunity is governed primarily by T cell receptor (TCR) recognition of peptide-human leukocyte antigen (pHLA) complexes and is essential for immunosurveillance and disease control. This interaction is

T cells are integral players in the cell-mediated adaptive immune response, due to the expression of a specific antigen receptor, the alpha–beta T cell receptor (αβ TCR) on their

T cell receptor (TCR) engagement leads to actin polymerization at the site of T cell contact with antigen-presenting cells. Here we have studied the dynamic activity of proteins T cells are critical for co-ordinating the immune response. T cells are activated when their surface T cell receptors (TCRs) engage cognate antigens in the form of peptide

Classical αβ T cells protect the host by monitoring intracellular and extracellular proteins in a two-step process. The first step is protein degradation and combination with a The recognition of microorganisms by T cells is the central event in the adaptive immune response to infection. Each T cell expresses a unique T-cell antigen receptor (TCR), The specificity of T cell activation is achieved by tightly regulated T cell receptor (TCR) recognition of antigenic peptides in complex with major histocompatibility complex (pMHC) glycoproteins presented by antigen

Researchers are unravelling the molecular signaling pathways that activate T cells, white blood cells which play a central role in the immune response. Sung-Gyoo Park and

Theoretical studies of T cell receptor signalling and T cell activation have become a well-known part of immunology and the models described in this chapter provide a good basis Wachsmann and colleagues explored whether dual-antigen specificity could be installed on T cells using combined TCR and CAR engineering to prevent immune escape after

Our primary goal in this review is to highlight the role of molecular flexibility in governing molecular interactions required for antigen processing, presentation, and Fluorescence resonance energy transfer (FRET) imaging allows the investigation of protein–protein interactions in live cells, and has demonstrated that T-cell receptors (TCRs) Abstract T cell antigen receptors (TCR) on the surface of T cells bind specifically to particular peptide bound major histocompatibility complexes (pMHC) presented on the surface of antigen

Functional and structural analyses reveal how components of αβ and γδ TCR gene loci combine to create T cells with unique patterns of antigen recognition. Abstract αβ and γδ T T cells are critical for cells are The mechanisms by which a T cell detects antigen using its T cell antigen receptor (TCR) are crucial to our understanding of immunity and the harnessing of T cells

Accordingly, for any given T cell, the TCR specificity is determined by both the antigenic peptide and the particular MHC molecule the peptide binds. This property, called

Description: The CD8β recAb (YTS156.7.7) reacts with the ~25 kDa beta subunit of mouse CD8αβ, also known as Ly-3, Lyt-3, CD8β or CD8 beta subunit [1]. CD8αβ acts as a co-receptor Over the past decade, key protein interactions contributing to T cell antigen recognition have been characterized in molecular detail. These have included interactions involving the T cell antigen

However, recognition of foreign molecules can be achieved by monovalent binding domains, as evidenced by the T-cell antigen receptor and various innate immune receptors. Despite extensive investigations into the biochemical signaling events triggered by antigen recognition in these cells, our ability to predict or control the outcome of T and B cell

Antigen receptors recognize specific molecular structures and recruit adaptors through their effector domains, triggering trans-membrane transduction signaling pathway to
