Plasma kynurenine/tryptophan (KT) ratio, a marker of adaptive immune defects, strongly predicts mortality during treated HIV disease in Ugandans compared to U.S.-based populations, Here, KT ratio, and T cell and plasma biomarkers of immune activation were measured among 535 HIV-infected Ugandans prior to ART initiation and at month 6 of viral suppression. Month 6 KT ratio (aHR=2.74), sCD14 (aHR=2.32), IL-6 (aHR=2.34), and D dimer (aHR=1.95) were associated with mortality occurring ≥6 months after ART initiation, KT ratio remained significantly predictive of mortality even after adjustment for the additional biomarkers, suggesting an independent contribution to clinical outcomes in resource-limited settings...

Background: Despite the availability of curative treatment for hepatitis C virus (HCV) infection, because of cost, treatment is often denied until liver fibrosis has progressed to at least moderate fibrosis and in some cases cirrhosis. That practice is justified on assumptions that there are no medical consequences to having moderate disease and that disease stage transitions can be anticipated. Methods: We performed transient elastography on 964 people chronically infected with HCV with a history of injection drug use living in Baltimore, Maryland...

Oropharyngeal candidiasis (OPC), caused predominantly by Candida albicans, is a prevalent infection in patients with advanced AIDS, defects in Th17 immunity, and head and neck cancer. A characteristic feature of OPC is fungal invasion of the oral epithelial cells. One mechanism by which C. albicans hyphae can invade oral epithelial cells is by expressing the Als3 and Ssa1 invasins that interact with the epidermal growth factor receptor (EGFR) on epithelial cells and stimulate endocytosis of the organism. However, the signaling pathways that function downstream of EGFR and mediate C...

Context: Currently, no recurrence or mortality risk systems consider molecular testing when predicting thyroid cancer outcomes. Objective: We developed an integrative prognostic system that incorporates TERT promoter mutations into the recently proposed risk reclassification system after initial therapy (dynamic risk stratification, DRS) to better categorize and predict outcomes. Design: A total of 357 differentiated thyroid cancer patients without initial distant metastasis were enrolled...

Type 1 regulatory T (Tr1) cells play a pivotal role in restraining human T-cell responses toward environmental allergens and protecting against allergic diseases. Still, the precise molecular cues that underlie their transcriptional and functional specification remain elusive. Here, we show that the cytokine activin-A instructs the generation of CD4(+) T cells that express the Tr1-cell-associated molecules IL-10, inducible T-Cell costimulator (ICOS), lymphocyte activation gene 3 protein (LAG-3), and CD49b, and exert strongly suppressive functions toward allergic responses induced by naive and in vivo-primed human T helper 2 cells...

Glioblastoma (GBM) progression is associated with metabolic remodeling in both glioma and immune cells, resulting in the use of aerobic glycolysis as the main source of energy and biosynthetic molecules. The transcription factor hypoxia-inducible factor (HIF)-1α drives this metabolic reorganization. Oxygen levels, as well as other factors, control the activity of HIF-1α. In addition, the ligand-activated transcription factor aryl hydrocarbon receptor (AHR) modulates tumor-specific immunity and can also participate in metabolic remodeling...

BACKGROUND: Isolated superficial vein thrombosis (iSVT) (without concomitant deep vein thrombosis (DVT) or pulmonary embolism (PE)) is a frequent event but available data on long-term outcomes are scarce and retrospective. Therefore, we aimed to determine prospectively the risk and type of venous thromboembolic (VTE) recurrence after iSVT and compare it with that of proximal DVT. METHODS: Using data from the prospective, multicentre, observational, OPTIMEV study, we assessed at three years and after anticoagulants were stopped, the incidence and the type of VTE recurrence (iSVT/DVT/PE) of patients with a first objectively confirmed iSVT without cancer (n=285) and compared this to patients with a first proximal DVT without cancer (n=262)...

BACKGROUND/PURPOSE: Diabetes portends an increased risk of adverse early and late outcomes in patients undergoing PCI. In this study, we aimed to investigate if the adverse effect of diabetes mellitus (DM) on early and late PCI outcomes is reduced with drug-eluting (DES) compared to bare-metal (BMS) stents. METHODS/MATERIALS: We reviewed the Mount Sinai Beth Israel Hospital first PCI experience for multivessel coronary artery disease (CAD, 1998-2009). Patients were excluded if they had single-vessel CAD, emergency, no stent, prior bypass graft or myocardial infarction <24h...

Innate lymphoid cells (ILC) are members of a heterogeneous family with a lymphoid origin that mimics the T helper (Th) cytokine profile. ILC are involved in early effector cytokine-mediated responses during infections in peripheral tissues. ILC also play an important role in chronic skin inflammatory diseases, including psoriasis. Although classical ILC express CD127, it has been recently reported that the presence of non-classical CD127(-) ILC populations and an early ILC precursor (EILP) CD127(low). ILC development has predominately been investigated in mouse models...

AIMS: Coffee consumption has been epidemiologically associated with a lower risk for liver cirrhosis and cancer. UDP-glucuronosyltransferases (UGT1A) catalyze the detoxification of reactive metabolites thereby acting as indirect antioxidants. Aim of the study was to examine UGT1A regulation in response to Benzo[α]pyrene (BaP) to elucidate the potentially protective effects of coffee on BaP-induced oxidative stress and toxicity. RESULTS: In cell culture (HepG2, KYSE70 cells) and in htgUGT1A-WT mice, UGT1A transcription was activated by BaP, while it was reduced or absent htgUGT1A-SNP (containing 10 commonly occurring UGT1A-SNPs) mice...
