Notes:
Murine γ/δ T lymphocytes localize to different epithelial tissues and are phenotypically distinct from peripheral γ/δ T cell-populations in that they show limited TCR diversity, express the CD8 α/α homodimer and lack the CD8β chain. In humans, a compartmentalization of γ/δ cells sharing similar phenotypic features has been documented to date only in the case of intestinal epithelium. In the present study we show that about half of Vδ1+ (as well as Vδ1−Vδ2−) γ/δ lymphocytes, which can be selectively expanded from human lung cancers, coexpress the CD8α/α homodimer. The accumulation of intraepithelial CD8+γ/δ+ lymphocytes might then be a more general phenomenon, possibly as a result of common mechanisms operating at those sites.
