CD30L/CD30 is critical for maintenance of IL-17A-producing γδ T cells bearing Vγ6 in mucosa-associated tissues in mice.

CD30 ligand (CD30L, CD153), a member of the tumor necrosis factor (TNF) superfamily, and its receptor CD30 are important for differentiation and activation of CD4(+) T helper type 17 (Th17) cells. In this report, we demonstrate that the interleukin 17A (IL-17A)-producing γδ T cells normally developed in the fetal thymus, whereas Vγ1(-)Vγ4(-) γδ T cells expressed Vγ6/Vδ1 gene transcript selectively decreased in mucosa-associated tissues in naive CD30KO or CD30LKO mice. Moreover, CD30 and CD30L were expressed preferentially by Vγ1(-)Vγ4(-) γδ T cells in naive mice. The bacteria clearance was attenuated by the impaired response of the IL-17A-producing γδ T cells and decreased infiltration of neutrophils in CD30KO or CD30LKO mice. In vivo administration of agonistic anti-CD30 monoclonal antibody restored the ability of protection against Listeria monocytogenes by enhancing Vγ1(-)Vγ4(-) γδ T cells producing IL-17A not only in wild-type but also CD30LKO mice. Taken together, it appears that CD30L/CD30 signaling plays an important role in the maintenance and activation of IL-17A-producing γδ T cells presumably bearing Vγ6 in the mucosa-associated tissues of mice.
