What is the T-cell receptor (TCR)? (abridged
... The αβ version of the TCR was described on the previous page. The αβ type is more common, however another TCR type called γδ can also exist. This type of receptor is made up of gamma (γ) and delta (δ) proteins. These are also composed of subunits, but are different from αβ. The type of TCR that is f ...
