Complement-activating anti-HLA donor-specific antibodies (DSAs) are associated with impaired kidney transplant outcome; however, whether these antibodies induce a specific rejection phenotype and influence response to therapy remains undetermined. We prospectively screened 931 kidney recipients for complement-activating DSAs and used histopathology, immunostaining, and allograft gene expression to assess rejection phenotypes. Effector cells were evaluated using human cell cultures.

Objective: In most patients with nonsevere systemic necrotizing vasculitides (SNVs), remission is achieved with glucocorticoids alone, but one-third experience a relapse within 2 years. This study was undertaken to determine whether the addition of azathioprine (AZA) to glucocorticoids could achieve a higher sustained remission rate of newly diagnosed nonsevere eosinophilic granulomatosis with polyangiitis (Churg-Strauss) (EGPA), microscopic polyangiitis (MPA), or polyarteritis nodosa (PAN).

Methods: All patients included in this double-blind trial received glucocorticoids, gradually tapered over 12 months, and were randomized to receive AZA or placebo for 12 months, with stratification according to SNV (EGPA or MPA/PAN).

Recent data have confirmed the negative impact of preformed donor-specific antibodies (pDSAs) after liver transplantation (LT). In order to reduce the risk of developing lesions associated with acute and chronic antibody-mediated rejection in LT recipients, we evaluated the consequences in terms of transplant accessibility, associated with avoiding pDSAs according to several mean fluorescence intensity (MFI) titer thresholds that have been previously reported to be relevant in LT. Among the 484 included LT candidates, 99 (20.

Background: Findings from uncontrolled studies suggest that addition of pegylated interferon in patients with HBe antigen (HBeAg)-negative chronic hepatitis B receiving nucleos(t)ide analogues with undetectable plasma hepatitis B virus (HBV) DNA might increase HBs antigen (HBsAg) clearance. We aimed to assess this strategy.

Methods: In this randomised, controlled, open-label trial, we enrolled patients aged 18-75 years with HBeAg-negative chronic hepatitis B and documented negative HBV DNA while on stable nucleos(t)ide analogue regimens for at least 1 year from 30 hepatology tertiary care wards in France.

Electronic address:

Circulating mixed cryoglobulins are detected in 40%-60% of patients with hepatitis C virus (HCV) infection, and overt cryoglobulinemia vasculitis (CryoVas) develops in approximately 15% of patients. Remission of vasculitis has been associated with viral clearance, but few studies have reported the effectiveness of direct-acting antiviral drugs in these patients. We performed an open-label, prospective, multicenter study of the effectiveness and tolerance of an all-oral, interferon- and ribavirin-free regimen of sofosbuvir plus daclatasvir in patients with HCV-associated CryoVas.

C-type lectin receptor DCIR modulates immunity to tuberculosis by sustaining type I interferon signaling in dendritic cells.

Proc Natl Acad Sci U S A

January 2017

Institut de Pharmacologie et de Biologie Structurale (IPBS), CNRS, 31000 Toulouse, France;

Immune response against pathogens is a tightly regulated process that must ensure microbial control while preserving integrity of the infected organs. Tuberculosis (TB) is a paramount example of a chronic infection in which antimicrobial immunity is protective in the vast majority of infected individuals but can become detrimental if not finely tuned. Here, we report that C-type lectin dendritic cell (DC) immunoreceptor (DCIR), a key component in DC homeostasis, is required to modulate lung inflammation and bacterial burden in TB.

Institut de Recherche en Santé Digestive, Université de Toulouse, Institut National de la Santé et de la Recherche Médicale, Institut National de la Recherche Agronomique, Ecole Nationale Vétérinaire de Toulouse, Université Paul Sabatier, Toulouse, France;

Protease-activated receptors PAR1 and PAR2 play an important role in the control of epithelial cell proliferation and migration. However, the survival of normal and tumor intestinal stem/progenitor cells promoted by proinflammatory mediators may be critical in oncogenesis. The glycogen synthase kinase-3β (GSK3β) pathway is overactivated in colon cancer cells and promotes their survival and drug resistance.
