In this study we describe the expression of two T cell receptor (TCR) gamma chains on the surface of a human T cell clone isolated from the peripheral blood. Each gamma chain was part of an independent and functional TCR. The dual receptor T cell clone (and all subclones derived from this clone) had stable expression of this phenotype. Immunoprecipitation studies revealed the expression of non-disulfide linked TCRs by this V gamma 4+V gamma 9+V delta 1+ T cell clone, which was in agreement with the finding that both V gamma gene transcripts were rearranged to C gamma 2-associated joining elements. Both gamma chains were derived from productive rearrangements of different (allelic) genes coding for a V gamma 4+ and a V gamma 9+ gamma-chain, and both were coupled to a V delta 1+ delta chain. Incubation of this V gamma 4+V gamma 9+V delta 1+ T cell clone with TCR gamma-chain-specific MoAbs rapidly induced an increase in intracellular Ca++, indicating that both gamma-chains are functional. Furthermore, this clone responded to stimulation with S. aureus derived superantigens. We suggest therefore that exogenous (super)antigens can trigger dual receptor T cells resulting in activation of these T cells.
