This study aimed to evaluate the effects of vitamin C and vitamin E on antioxidant capacity and immune function in oxidative-stressed breeder roosters. One hundred twenty 45-week-old Lveyang black-boned breeder roosters were randomly assigned to 5 dietary treatments, including negative control group (NC), positive control group (PC), and 3 trial groups, which were fed the diets containing 300 mg/kg VC, 200 mg/kg VE, or 300 mg/kg VC and 200 mg/kg VE (VC+VE). At 47 wk of age, the positive control and trial groups were subcutaneously injected 3 times every other d with dexamethasone (DEX) 4 mg/kg of body weight, the negative control group was injected with saline...

Evidence to-date collectively points to a detrimental role of the type I IFN response during tuberculosis. The mechanisms underpinning the IFNαβ-mediated exacerbation of the disease is unclear. The 2'-5'-oligoadenylate synthetases (OAS), namely OAS1, OAS2 and OAS3 are part of the interferon-induced genes which until now have been synonymous with an anti-viral function. Blood transcriptome profiling has continuously observed their upregulation in a number of gene expression signatures which discriminate active TB from latent TB infection, however the role of the OASs and the effect that their expression has on the pathogenesis and persistence of TB is unknown...

Due to immunosenescence, older adults are particularly susceptible to lung-based viral infections, with increased severity of symptoms in those with underlying chronic lung disease. Repeated respiratory viral infections produce lung maladaptations, accelerating pulmonary dysfunction. Toll like 3 receptor (TLR3) is a membrane protein that senses exogenous double-stranded RNA to activate the innate immune response to a viral infection. Polyinosinic-polycytidylic acid [poly(I:C)] mimics double stranded RNA and has been shown to activate TLR3...

Columnaris disease (CD) caused by Flavobacterium columnare (F. columnare) is lack of knowledge on effective treatment measures. Bacterial pathogens require iron as an essential nutrient to infect the host. While hepcidin acts as a master regulator in iron metabolism, its contribution to host defense is emerging as complex and multifaceted. In vitro, recombinant Ctenopharyngodon idellus (C. idellus) hepcidin (CiHep) and synthetic CiHep both showed the ability to increase the expression of hepcidin and ferritin in C...

Generation of new β cells is an important approach in the treatment of type 1 diabetes mellitus (type 1 DM). Adipose tissue-derived stem cells (ADSCs) might be one of the best sources for cell replacement therapy for diabetes. Therefore, this work aimed to test the possible role of transplanted insulin-producing cells (IPCs) differentiated from ADSCs in treatment of streptozotocin (STZ) induced type I DM in rats. Type 1 DM was induced by single intra peritoneal injection with STZ (50 mg/kg BW). Half of the diabetic rats were left without treatment and the other half were injected with differentiated IPCs directly into the pancreas...

Poor sleep quality leads to increased immune activation and immune activation leads to worse sleep quality. South African HIV positive patients typically have delayed start of treatment, which has been associated with CD4+ effector T cells being more spontaneously activated in chronically treated patients. This cross-sectional study investigated whether subjective sleep quality was associated with CD4+ T lymphocyte reconstitution in treated South African HIV+ patients. One hundred and thirty-nine treated HIV+ patients (109 F, age average (SD)= 43 (9)) were recruited from Chris Hani Baragwanath Academic Hospital in Soweto, Johannesburg, South Africa...

BACKGROUND & AIMS: Glycogen synthase kinase 3β (Gsk3β) is a ubiquitously expressed kinase with distinctive functions in different types of cells. Although its roles in regulating innate immune activation and ischemia and reperfusion injuries (IRI) have been well documented, underlying mechanisms remain ambiguous, due in part to the lack of cell-specific tools in vivo. METHODS: We created a myeloid-specific Gsk3β KO strain to study its function in macrophages in a murine liver partial warm ischemia model...

BACKGROUND & AIM: Chronic infection with hepatitis B virus (HBV) in children possesses a serious health problem worldwide. It remains unresolved how children with immune-tolerant chronic hepatitis B should be treated, who were commonly characterized by HBeAg positivity, high viral load, normal or mildly elevated ALT and no or minimal inflammation in liver histology. This trial aims to study the benefits of antiviral therapy in children with these characters. METHODS: This is a pilot open-lable randomized controlled study...

Autophagy of cytoplasmic components plays an essential role in the pathogenic infection process. Furthermore, research suggests that autophagy is an extremely important component of the innate immune response. Our study aimed to reveal the effect of virus-induced autophagy on pseudorabies virus (PRV) replication. Our results confirmed that light chain 3 (LC3)-I was converted into LC3-II after PRV infection; this transition is considered an important indicator of autophagy. Transmission electron microscopy (TEM) revealed that PRV infection could notably increase the number of autophagosomes in mouse neuro-2a (N2a) cells...

Alopecia areata (AA) is a common autoimmune disease, with a lifetime risk of ∼2%. In AA, the immune systems targets the hair follicle, resulting in clinical hair loss. AA prognosis is unpredictable, and currently there is no definitive treatment. Our previous whole genome expression studies identified active immune circuits in AA lesions, including common γ-chain cytokine and IFN pathways. Since these pathways are mediated through JAK kinases, we prioritized clinical exploration of small molecule JAK inhibitors...

Eradicating HIV-1 infection is difficult because of the reservoir of latently infected cells that gets established soon after infection, remains hidden from antiretroviral drugs and host immune responses, and retains the capacity to reignite infection following the cessation of treatment. Drugs called latency-reversing agents (LRAs) are being developed to reactivate latently infected cells and render them susceptible to viral cytopathicity or immune killing. Whereas individual LRAs have failed to induce adequate reactivation, pairs of LRAs have been identified recently that act synergistically and hugely increase reactivation levels compared to individual LRAs...

Hepatitis C virus (HCV) infection is widely diffused in general population, and the likelihood that an infected individual is affected by other disesases is high. A lot of epidemiological and explicative studies, even if with different levels of evidence, reported a potential effect of HCV infection -by direct and indirect mechanisms- on the pathogenesis of extrahepatic comorbidities related to dysregulation of the immune system, or cardiometabolic comorbidities like diabetes, neuropsychiatric disorders, chronic kidney disease, cardiovascular alterations, etc...

Mast cells are immune cells that mature within the host tissue. The acquired phenotype is dictated by the tissue microenvironment, giving rise to diverse tissue-dependent phenotypes and functions. The lack of cellular models reflecting phenotypes found in vivo and important differences between human and rodent mast cells are obstacles to the understanding of their exact role in several pathophysiological processes. Studies published over the past few years showed that mast cells' role lies far beyond their involvement in allergy and anaphylaxis...

Rutin has anti-inflammatory, antioxidant, anti-viral, anti-tumor and immune regulatory effects. However, the neuroprotective effects of rutin in spinal cord injury are unknown. The p38 mitogen activated protein kinase (p38 MAPK) pathway is the most important member of the MAPK family that controls inflammation. We assumed that the mechanism of rutin in the repair of spinal cord injury is associated with the inhibition of p38 MAPK pathway. Allen's method was used to establish a rat model of spinal cord injury...

Systematic inflammatory response after spinal cord injury (SCI) is one of the factors leading to lesion development and a profound degree of functional loss. Anti-inflammatory compounds, such as curcumin and epigallocatechin gallate (EGCG) are known for their neuroprotective effects. In this study, we investigated the effect of combined therapy of curcumin and EGCG in a rat model of acute SCI induced by balloon compression. Immediately after SCI, rats received curcumin, EGCG, curcumin + EGCG or saline [daily intraperitoneal doses (curcumin, 6 mg/kg; EGCG 17 mg/kg)] and weekly intramuscular doses (curcumin, 60 mg/kg; EGCG 17 mg/kg)] for 28 days...

Current Neuroscience dogma holds that transections or ablations of a segment of peripheral nerves produce: (1) Immediate loss of axonal continuity, sensory signaling, and motor control; (2) Wallerian rapid (1-3 days) degeneration of severed distal axons, muscle atrophy, and poor behavioral recovery after many months (if ever, after ablations) by slowly-regenerating (1 mm/d), proximal-stump outgrowths that must specifically reinnervate denervated targets; (3) Poor acceptance of microsutured nerve allografts, even if tissue-matched and immune-suppressed...

Dipeptidyl peptidase IV (DPP-IV) is a serine protease best known for its role in inactivating glucagon-like peptide-1 (GLP-1), pituitary adenylate cyclase-activating polypeptide (PACAP) and glucose-dependent insulinotropic peptide (GIP), three stimulators of pancreatic insulin secretion with beneficial effects on glucose disposal. Owing to the relationship between DPP-IV and these peptides, inhibition of DPP-IV enzyme activity is considered as an attractive treatment option for diabetic patients. Nonetheless, increasing studies support the idea that DPP-IV might also be involved in the development of neurological disorders with a neuroinflammatory component, potentially through its non-incretin activities on immune cells...

OBJECTIVES: Therapies with low doses of radon have beneficial effects on patients suffering from chronic painful degenerative and inflammatory diseases. We already showed that this is accompanied by systemic immune modulations. We here focus on pain reducing effects of very low doses of radon by adding carbon dioxide water and its impact on heart rate variability (HRV), blood pressure and free radicals. METHODS: 100 patients receiving radon spa (1.200 Bq/l at 34°C or 600 Bq/l, 1 g/l CO 2 at 34°C) were monitored before and at three different time points after therapy...

BACKGROUND: Utilization of liver grafts from hepatitis B core antibody (anti-HBc) positive donors carries the risk of reactivation of hepatitis B virus (HBV) in recipients because of post-transplant immunosuppressive therapy. METHODS: This was a retrospective study of patients who had received liver grafts from anti-HBc positive live donors between 2006 and 2016 at our institute. RESULTS: Out of 22 recipients [all males, mean age 45.4 years (range 18-64 years)], four patients were hepatitis B surface antigen (HBsAg) positive preoperatively and received entecavir post-transplantation...
