NKG2D is a C-type lectin-like receptor in the CD94/NKG2 family and is expressed by a variety of leukocyte populations including natural killer (NK) cells, γδ T cells, CD8+ T cells and certain innate lymphoid cell (ILC) subsets. NKG2D can bind proteins in two protein families – MIC and RAET1/ULBP. Expression of NKG2D ligands is low/absent under homeostatic conditions, but these proteins are upregulated in several contexts, including infection, cancer, physiologic stress, and senescence. NKG2D-driven activation of NK and CD8+ T cells has previously been shown to result in augmented control of infections and tumor growth. However, the role of NKG2D in the context of tissue injury and repair has not been established. Here we tested the effects of augmented NKG2D ligation in the context of a skin injury model. Biopsy punches were used to generate six 3- mm wounds on the dorsal surface of C57BL/6 mice. On days 0 and 1, NKG2D stimulating antibodies or isotype controls were injected into the peritoneal cavity and wound healing was assessed daily. Mice treated with NKG2D activating antibodies had more rapid wound repair than controls – wounds were healed by day 5 in NKG2D-treated mice as compared to day 7 in controls. Analogous results were observed in an ex vivo human skin model. Using a biolistic particle delivery system to induce upregulation of RAE (an NKG2D ligand), we observed more rapid wound repair compared to controls. Genetic ablation of NKG2D resulted in a 40% delay in wound healing. Moreover, depletion of NK1.1+ or CD8+ leukocytes blunted the benefit of NKG2D ligation, suggesting that T cells, NK cells, and/or ILCs may play a role in driving tissue repair. Thus, we demonstrate a potential therapeutic function of NKG2D engagement in tissue regeneration.
