 AB    Gamma delta cells participate in pathogenic infections and autoimmune
       conditions, yet, almost a decade after their discovery, little is known
       regarding their TCR repertoire or effector functions. Unlike
       MHC-restricted antigen recognition employed by TCR alpha beta cells, TCR
       gamma delta cells can recognize whole unprocessed antigens in an MHC-
       independent manner. The nature of positive and negative selection used
       to shape the repertoire of TCR gamma delta cells is unclear, especially
       in the nonlymphoid tissues where these cells predominate. While TCR
       gamma delta cells express an activated phenotype and are present in
       pathological conditions, their roles in immunological protein is
       unknown. This review will focus on our efforts to study these issues of
       TCR gamma delta biology.
