T cell receptor gamma/delta chain diversity
The TCR-gamma and -delta chains of six murine hybridomas were compared by one-dimensional SDS-PAGE and two-dimensional NEPHGE/SDS-PAGE analysis. This allowed the identification of three distinct gamma chains (gamma a, gamma b, and gamma c) and three distinct delta chains (delta a, delta b, and delta c). Four gamma/delta chain combinations (gamma a delta a, gamma b delta b, gamma b delta c, and ...
متن کاملDiversity of T-cell receptor Gene Rearrangements in South Indian Patients with Common Acute Lymphoblastic Leukemia
Background: Precursor B-Acute Lymphoblastic Leukemia (precursor B-ALL) oc-curs due to the uncontrolled proliferation of B-lymphoid precursors arrested at a par-ticular stage of B-cell development. Precursor-B-ALL is classified mainly into pro-B-ALL, common-ALL and pre-B-ALL. The Common Acute Lymphoblastic Antigen CD10 is the marker for common-ALL. Objective: This study was aimed to examine the ...
متن کاملGammadelta T cell function varies with the expressed WC1 coreceptor.
WC1 molecules are transmembrane glycoproteins belonging to the scavenger receptor cysteine-rich family and uniquely expressed on gammadelta T cells. Although participation of WC1+ gammadelta T cells in immune responses is well established, very little is understood regarding the significance of expressing different forms of the WC1 molecule. Two forms previously identified by mAbs, i.e., WC1.1 ...
متن کاملDisorderly conduct in gammadelta versus alphabeta T cell lineage commitment.
The mechanism of T cell precursor commitment to the gammadelta or alphabeta T cell lineage remains unclear. While TCR signal strength has emerged as a key factor in lineage commitment based on TCR transgenic models, the entire TCR repertoire may not possess the same discriminatory power. A counterbalance to the TCR as the lineage determinant is the pre-existing heterogeneity in gene expression ...
متن کاملStructure of the Vdelta domain of a human gammadelta T-cell antigen receptor.
Antigen recognition by T lymphocytes is mediated by cell-surface glycoproteins known as T-cell antigen receptors (TCRs). These are composed of alpha and beta, or gamma and delta, polypeptide chains with variable (V) and constant (C) regions. In contrast to alphabeta TCRs, which recognize antigen only as peptide fragments bound to molecules of the major histocompatibility complex (MHC), gammadel...
