Human T cells are considered to play a vital role in protectiveimmunity through cytokine secretion and cytotoxic activity.We report that cells expressing the V2V2+T cell receptor(V2+ T cells) also display principal characteristics of professionalantigen-presenting cells such as dendritic cells. Thus, whenactivated, these cells efficiently processed and displayed antigensand provided co-stimulatory signals sufficient for strong inductionof naïve ß T cell proliferation and differentiation.We suggest that, upon microbial activation, V2+ T cells participatein the induction of adaptive immune responses and that thesecells may be a useful tool in vaccine development and immunotherapy.
