title: gammadelta T cell subsets: a link between TCR and function?
abstract: The gammadelta T lmphocytes are often divided into subsets based upon expression of certain TCR components. This division was initially made because gammadelta T cells residing in particular epithelia were found to show tissue specific differences in their TCRs. Many examples now show that gammadelta T cell subsets also appear to be biased to carry out particular functions. This suggests that particular gammadelta TCR types direct the cells to acquire a certain type of functional programming during thymic development. Here, we describe functionally distinct, TCR-defined gammadelta T cell subsets, and evidence that their functions are predetermined in the thymus.
