Abstract
Human Vγ9Vδ2 T cells recognize in a butyrophilin 3A/CD277-dependent way microbial (E)-4-hydroxy-3-methyl-but-2-enyl pyrophosphate (HMBPP) or endogenous pyrophosphates (isopentenyl pyrophosphate [IPP]). Nitrogen-bisphosphonates such as zoledronic acid (ZOL) trigger selective γδ T cell activation because they stimulate IPP production in monocytes by inhibiting the mevalonate pathway downstream of IPP synthesis. We performed a comparative analysis of the capacity of purified monocytes, neutrophils, and CD4 T cells to serve as accessory cells for Vγ9Vδ2 T cell activation in response to three selective but mechanistically distinct stimuli (ZOL, HMBPP, agonistic anti-CD277 mAb). Only monocytes supported γδ T cell expansion in response to all three stimuli, whereas both neutrophils and CD4 T cells presented HMBPP but failed to induce γδ T cell expansion in the presence of ZOL or anti-CD277 mAb. Preincubation of accessory cells with the respective stimuli revealed potent γδ T cell-stimulating activity of ZOL- or anti-CD277 mAb-pretreated monocytes, but not neutrophils. In comparison with monocytes, ZOL-pretreated neutrophils produced little, if any, IPP and expressed much lower levels of farnesyl pyrophosphate synthase. Exogenous IL-18 enhanced the γδ T cell expansion with all three stimuli, remarkably also in response to CD4 T cells and neutrophils preincubated with anti-CD277 mAb or HMBPP. Our study uncovers unexpected differences between monocytes and neutrophils in their accessory function for human γδ T cells and underscores the important role of IL-18 in driving γδ T cell expansion. These results may have implications for the design of γδ T cell-based immunotherapeutic strategies.

THE JOURNAL OF IMMUNOLOGY 2016; 196:2219-29. [PMID: 26819204 DOI: 10.4049/jimmunol.1501661] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/28/2015] [Accepted: 12/18/2015] [Indexed: 01/13/2023]
Abstract
Human Vγ9Vδ2 T cells are activated through their TCR by neighboring cells producing phosphoantigens. Zoledronate (ZOL) treatment induces intracellular accumulation of the phosphoantigens isopentenyl pyrophosphate and ApppI. Few attempts have been made to use immunomanipulation of Vγ9Vδ2 lymphocytes in chronic viral infections. Although Vγ9Vδ2 T cells seem to ignore human CMV (HCMV)-infected cells, we examined whether they can sense HCMV when a TCR stimulus is provided with ZOL. Fibroblasts treated with ZOL activate Vγ9Vδ2 T cells to produce IFN-γ but not TNF. Following the same treatment, HCMV-infected fibroblasts stimulate TNF secretion and an increased production of IFN-γ, indicating that Vγ9Vδ2 cells can sense HCMV infection. Increased lymphokine production was observed with most clinical isolates and laboratory HCMV strains, HCMV-permissive astrocytoma, or dendritic cells, as well as "naive" and activated Vγ9Vδ2 cells. Quantification of intracellular isopentenyl pyrophosphate/ApppI following ZOL treatment showed that HCMV infection boosts their accumulation. This was explained by an increased capture of ZOL and by upregulation of HMG-CoA synthase and reductase transcription. Using an experimental setting where infected fibroblasts were cocultured with γδ cells in submicromolar concentrations of ZOL, we show that Vγ9Vδ2 cells suppressed substantially the release of infectious particles while preserving uninfected cells. Vγ9Vδ2 cytotoxicity was decreased by HCMV infection of targets whereas anti-IFN-γ and anti-TNF Abs significantly blocked the antiviral effect. Our experiments indicate that cytokines produced by Vγ9Vδ2 T cells have an antiviral potential in HCMV infection. This should lead to in vivo studies to explore the possible antiviral effect of immunostimulation with ZOL in this context.
