T-Cell Receptor beta-Chain Genes (n.). T cells have receptors that are activated exclusively by a target antigen. The T Cell Receptor The defining feature of T cells is the expression of the T cell receptor (TCR) on the surface of the cell. The TCR is a disulfide-linked membrane bound heterodimeric protein normally consisting of the highly variable α and β chains expressed as part of a complex with the invariant CD3 chain molecules. 1. T cells expressing these two chains are referred to as α:β (or αβ) T cells, though a minority of T cells express an alternate receptor, formed by variable γ and σ chains, referred as γσ T cells. T helper cells activate both T cells and B cells. T cell receptor (TCR) signaling is essential for development and the peripheral maturation and activation of T lymphocytes, both of which are required for an appropriate adaptive immune response. T-Cell Receptor alpha Genes (n.) 1. TCRs are unable to bind antigen directly, the antigen is broken down into peptides and presented to the T cell by antigen presenting cells (APC) such as dendritic cells and macrophages. n.
