- W2326014721 abstract "Event Abstract Back to Event Exploiting NKG2D and lymphoid stress surveillance response in seronegative spondyloarthritis Elisa Binda1*, Antonio Manzo1, Barbara Vitolo2, Serena Bugatti1, 2 and Carlomaurizio Montecucco1, 2 1 University of Pavia, Italy 2 IRCCS University Hospital San Matteo Foundation, Italy A number of biomarkers are currently being investigated in patients with seronegative spondyloarthitis (SpA) since they may be used to predict exacerbation and monitor the clinical response to an intervention. Natural killer group 2, member D (NKG2D) is an activating receptor present on the surface of natural killer (NK), CD8 T cells, γδ T cells and under certain conditions CD4 T cells. NKG2D receptor binds to a family of ligands that are distant relatives of major histocompatibility complex class I molecules. Environmental stress such as genotoxic/oxidative stress, heat shock and viral infections stimulate NKG2D ligands expression. Recent studies have demonstrated that NKG2D ligands are induced on proliferating rheumatoid arthritis (RA) synoviocytes and may thus contribute to progression of rheumatic disease. Here we investigate the expression of NKG2D ligands in synovial tissue from SpA patients and we compare it with samples from RA patients and healthy controls. We monitor NKG2D regulation also in in-vitro cultured SpA and RA synoviocytes in response to physiological stimuli such as oxidative stress, heat-shock and mechanic stretch. Downregulation of NKG2D receptor on peripheral blood mononuclear cells (PBMC) represents a physiological regulatory mechanism of NK and gd T cells in response to activation and it is mediated by the production of pro-inflammatory proteins. Hence the production of key cytokines by circulating NKG2D+ cells may indicate the impaired response of the immune system to stress in rheumatic disease. We believe that understanding the contribution of NKG2D pathway in rheumatic pathologies may provide rational for emerging targeted therapies Keywords: NKG2D, NKG2D ligands, seronegative spondyloarthritis, lymphoid stress surveillance, Autoimmunity Conference: 15th International Congress of Immunology (ICI), Milan, Italy, 22 Aug - 27 Aug, 2013.
