“Objectives. To characterize a novel anti-NKG2A autoantibody detected in a patient with SLE during a severe flare, and in a cross-sectional study investigate the occurrence of such autoantibodies in patients with SLE and primary SS (pSS).\n\nMethods. Serum or IgG from patients with SLE, pSS and healthy volunteers were assayed for blocking of anti-NKG2A or HLA-E binding to peripheral blood mononuclear cells or CD94/NKG2A- and CD94/NKG2C-transfected Ba/F3 cells. The anti-NKG2A autoantibodies were evaluated for effect on NK cell degranulation in response to HLA-E-transfected GSK1838705A price K562 cells. IFN-alpha was determined by an immunoassay and disease activity by the SLEDAI score.\n\nResults. Anti-NKG2A autoantibodies, which blocked binding of HLA-E tetramers to CD94/NKG2A-transfected cells and impaired NKG2A-mediated inhibition of NK cell activation, were observed in a patient with SLE. The

JQ1 presence of anti-NKG2A autoantibodies was associated with high SLE disease activity (SLEDAI score 14 and 16) and increased serum IFN-alpha. Of 94 SLE, 60 pSS and 30 healthy donor sera, only the index patient serum contained anti-NKG2A autoantibodies.\n\nConclusion. The presence of autoantibodies targeting NKG2A is a rare event, but when such autoantibodies occur they may promote excessive

NK cell function. This can contribute to the pathogenesis by increasing the killing of cells and the release of autoantigens. Our findings highlight the possible importance of NK cells in the SLE disease process.”
“Purpose: To assess the effect of the extent of stern graft coverage and anatomic properties of aortic dissection on the outcomes of thoracic endovascular aortic repair (TEVAR) for complicated Chronic type B aortic dissection (CCBAD) in terms of survival, reintervention, and false lumen thrombosis.\n\nMaterials GANT61 in vitro and Methods: A retrospective analysis was performed of 71 patients who underwent TEVAR for CCBAD. Mean patient age was 54.7 years. Distal extent of stent graft coverage was categorized as short (<= T7) or long (>= T8) coverage: Indications of reintervention were categorized into three groups: proximal, alongside, and distal according to the anatomic relationship of the culprit lesion and the stent graft. Overall survival, reintervention-free survival, and extent of false lumen thrombosis were compared.\n\nResults: The technical success rate was 97.2%. The 1-year, 3-year, and 5-year overall survival rates were 97.1%, 88.9%, and 88.9%, and 1-year, 3-year, and 5-year reintervention-free survival rates were 80.7%, 73.8%, and 60.6%.
