Interleukin 17 (IL-17) is an important inducer of tissue inflammation and is involved in numerous autoimmune diseases. However, how its signal transduction is regulated is not well understood. Here, we report that nuclear Dbf2-related kinase 1 (NDR1) functions as a positive regulator of IL-17 signal transduction and IL-17-induced inflammation. NDR1 deficiency or knockdown inhibits the IL-17-induced phosphorylation of p38, ERK1/2, and p65 and the expression of chemokines and cytokines, whereas the overexpression of NDR1 promotes IL-17-induced signaling independent of its kinase activity...

We herein report the porous 4-fold interpenetrated mog (moganite) metal-organic framework (MOF) [Cd3(tipp)(bpdc)2]·DMA·9H2O (1·Cd; H2tipp = 5,10,15,20-tetrakis(4-(imidazol-1-yl)phenyl)porphyrin, H2bpdc = biphenyl-4,4'-dicarboxylic acid, DMA = N,N'-dimethylacetamide). The incorporation of Cd and carboxylate oxygen affords 1·Cd rich Lewis acid and basic sites. This MOF 1·Cd was then applied as an efficient heterogeneous catalyst for the important cyanosilylation of aldehydes and Knoevenagel condensation reactions...

BACKGROUND: Pulmonary large cell neuroendocrine carcinoma (LCNEC) is pathologically classified as non-small-cell lung cancer (NSCLC), but its clinical behavior is more aggressive than other types of NSCLC. Accordingly, the optimal treatment strategy for LCNEC, including the indication of adjuvant treatment, remains controversial. METHODS: A retrospective review of 139 patients who underwent curative-intent surgery for LCNEC was performed to investigate clinicopathologic features and survival outcomes and to evaluate whether adjuvant treatment affected survival outcomes...

Autoimmune Th1 and Th17 responses are critical for the development of central nervous system (CNS) pathology in experimental autoimmune encephalomyelitis (EAE), an animal model for human multiple sclerosis. Although macrophages play important roles in the development of Th1 and Th17 responses, whether modulating macrophage gene transcription can diminish Th1- and Th17 cell-induced CNS pathology is unclear. In this study, we successfully silenced the expression of the transcription factor c-Rel in macrophages of mice with EAE (including those infiltrating the CNS) using chemically modified c-Rel-specific siRNAs delivered by nanoparticles...

CD40-CD154 interaction is critically involved in autoimmune diseases, and CD4 T cells play a dominant role in the Experimental Autoimmune Encephalomyelitis (EAE) model of Multiple Sclerosis (MS). CD4 T cells expressing CD40 (Th40) are pathogenic in type I diabetes but have not been evaluated in EAE. We demonstrate here that Th40 cells drive a rapid, more severe EAE disease course than conventional CD4 T cells. Adoptively transferred Th40 cells are present in lesions in the CNS and are associated with wide spread demyelination...

Abnormal neural activities can be revealed by resting-state functional magnetic resonance imaging (rs-fMRI) using analyses of the regional activity and functional connectivity (FC) of the networks in the brain. This study was designed to demonstrate the functional network alterations in the patients with pulsatile tinnitus (PT). In this study, we recruited 45 patients with unilateral PT in the early stage of disease (less than 48 months of disease duration) and 45 normal controls. We used regional homogeneity (ReHo) and seed-based FC computational methods to reveal resting-state brain activity features associated with pulsatile tinnitus...

Multiple sclerosis (MS) is an inflammatory demyelinating autoimmune disorder of the central nervous system (CNS) associated with severe neurological disability. Reactive oxygen species (ROS) and mitochondrial dysfunction play a pivotal role in the pathogenesis of this disease. Several members of the mitochondrial uncoupling protein subfamily (UCP2-UCP5) were suggested to regulate ROS by diminishing the mitochondrial membrane potential and constitute therefore a promising pharmacological target for MS. To evaluate the role of different uncoupling proteins in neuroinflammation, we have investigated their expression patterns in murine brain and spinal cord (SC) during different stages of experimental autoimmune encephalomyelitis (EAE), an animal model for MS...

There is a lack of evidence for treatment of pediatric multiple sclerosis (PedMS). Treatment using azathioprine for PedMS has not been reported. A 10-year-old boy with multiple sclerosis who was seropositive for antibodies against myelin oligodendrocyte glycoprotein (MOG)-IgG was treated with azathioprine plus oral methylprednisolone. The patient showed clinical and magnetic resonance imaging stability, with MOG-IgG seroconversion. There were no major side effects over a 5-year period. Azathioprine may be a treatment option, particularly in poor medical resource areas, for pediatric patients with multiple sclerosis who are seropositive for MOG-IgG...

Working memory (WM) refers to the holding and manipulation of information during cognitive tasks. Its underlying neural mechanisms have been explored through both functional magnetic resonance imaging (fMRI) and electroencephalography (EEG). Trial-by-trial coupling of simultaneously collected EEG and fMRI signals has become an important and promising approach to study the spatio-temporal dynamics of such cognitive processes. Previous studies have demonstrated a modulation effect of the WM load on both the BOLD response in certain brain areas and the amplitude of P3...

INTRODUCTION: Pre-clinical drug discovery for multiple sclerosis (MS) is a labor intensive activity to perform in rodent models. This is owing to the long duration of disease induction and observation of treatment effects in an experimental autoimmune encephalomyelitis (EAE) model. We propose a novel adult zebrafish based model which offers a quick and simple protocol that can used to screen candidates as a step between in vitro experiments and rodent studies. The experiments conducted for this manuscript were to standardize a suitable model of EAE in adult zebrafish and validate it using known modulators...

The CCAAT/Enhancer Binding Protein β (C/EBPβ) transcription factor is activated by multiple inflammatory stimuli, including IL-17 and LPS, and C/EBPβ itself regulates numerous genes involved in inflammation. However, the role of C/EBPβ in driving autoimmunity is not well understood. Here, we demonstrate that Cebpb(-/-) mice are resistant to EAE. Cebpb(-/-) mice exhibited reduced lymphocyte and APC infiltration into CNS following EAE induction. Furthermore, MOG-induced Th17 cytokine production was impaired in draining LN, indicating defects in Th17 cell priming...

Activated leukocyte cell adhesion molecule (ALCAM) is a cell adhesion molecule found on blood-brain barrier endothelial cells (BBB-ECs) that was previously shown to be involved in leukocyte transmigration across the endothelium. In the present study, we found that ALCAM knockout (KO) mice developed a more severe myelin oligodendrocyte glycoprotein (MOG)35-55-induced experimental autoimmune encephalomyelitis (EAE). The exacerbated disease was associated with a significant increase in the number of CNS-infiltrating proinflammatory leukocytes compared with WT controls...

Autoantibodies against myelin oligodendrocyte glycoprotein (MOG) are associated with autoimmune central nervous system diseases like acute disseminated encephalomyelitis (ADEM). For ADEM, it is speculated that a preceding infection is the trigger of the autoimmune response, but the mechanism connecting the infection to the production of MOG antibodies remains a mystery. We reasoned that the ability of B cells to capture cognate antigen from cell membranes, along with small quantities of coexpressed "bystander" antigens, might enable B-cell escape from tolerance...
