CD161 is a C-Type Lectin Receptor, also known as NKR-P1A, previously found on NKT cells and subsets of T-cells. Phenotyping of cells that are functionally producing IL-17 has shown the one constant marker is CD161. While it had been shown previously that human CD4+ cells that produce both IL-17 and IFNg give rise to Th17/Th1 cells, indicating common etiology of these two T cell subsets, a clear marker for cells producing IL-17 is CD161. In fact, all cells characterized as the following subsets CD4+TCRab+, CD8+TCRab+, CD4-CD8-TCRab+, and CD4-CD8-TCRgd+ bearing CD161 also produce IL-17 but cells of these same phenotypes and functional marker which do not bear CD161 also do not produce IL-17. Induction of CD161 expression by transduction with RORC also induces IL-1R and IL-23R as well as the ability to produce IL-17. The ability to produce IL-17 and the induction of CD161 shows a strong dependency for RORC. Antibody to CD161 provides a probe for identifying IL-17 producing cells and offers a finer delineation of additional subsets derived from Th17 and their functional characteristics through cytokine mRNA expression or production.
