alpha beta t cells,
There are 2 populations of T lymphocytes, αβ T and γδ T cells, that can be distinguished by the expression of either an αβ TCR or a γδ TCR, respectively. Pairing of the Ag binding heterodimer, which consists of TCR-α/TCR-β (TCRαβ) or TCR-γ/TCR-δ (TCRγδ), with proteins of the CD3 complex forms the co .
TIn humans, in 95% of T cells the TCR consists of an alpha (α) chain and a beta (β) chain (encoded by TRA and TRB, respectively), whereas in 5% of T cells the TCR consists of gamma and delta (γ/δ) chains (encoded by TRG and TRD, respectively).alpha beta t cells TIn humans, in 95% of T cells the TCR consists of an alpha (α) chain and a beta (β) chain (encoded by TRA and TRB, respectively), whereas in 5% of T cells the TCR consists of gamma and delta (γ/δ) chains (encoded by TRG and TRD, respectively).
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 surface.

Double-negative (DN) T cells are present at relatively low frequencies in human peripheral blood, and are characterized as expressing the alpha-beta or gamma-delta T-cell receptor (TCR), but not the CD4 nor the CD8 co-receptors.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. αβ and γδ T cells are disparate T cell lineages that can respond to distinct antigens (Ags) via the use of the αβ and γδ T cell Ag receptors (TCRs), respectively. There are two types of T cells that differ in their TCR: alpha/beta (αβ) T cells. Their TCR is a heterodimer of an alpha chain with a beta chain. Each chain has a variable (V) region and a constant (C) region. The V regions each contain 3 hypervariable regions that make up the antigen-binding site. gamma/delta (γδ) T cells.
T lymphocytes comprise two distinct lineages defined by the T cell antigen receptor (TCR) complex they express, αβ or γδ, and perform nonoverlapping roles in immune responses. αβ T cells are found primarily in secondary lymphoid organs, recognize peptide ligands in a major histocompatibility complex (MHC) restricted fashion, and respond to patho.
