Hepatitis C virus (HCV) is a major public health problem being the most common cause of chronic liver disease in Egypt. HCV-induced decompensated liver cirrhosis patients have a median survival of 2 years even with currently used new treatments. Silymarin is the most commonly used herbal product in chronic liver disease for its anti-inflammatory, antiviral, antioxidant, and antifibrotic effects. The aim of this study was to assess the effects of silymarin in high dose on the clinical and biochemical status of chronic HCV-associated decompensated liver cirrhosis...

Interferon regulatory factors (IRFs) are crucial regulators in initiating the host innate immune response against pathogen invasions. Dabry's sturgeon (Acipenser dabryanus) is particularly a valuable fish species found in the Yangtze River, China for which there is scarce immunological data. In the present study, we investigated the expression profile of sturgeon IRF genes. All adIRFs were composed of 8 exons and 7 introns, except adIRF1, which possessed 9 exons interrupted by 8 introns. Moreover, the predicted protein sequence has a DNA-binding domain (DBD) sharing high identity with spotted gar (Lepisosteus oculatus)...

Follistatin-like protein-1 (FSTL1) is an inflammatory factor that can induce an inflammatory response and is expressed in cancers. However, little is known about its content and function in nasopharyngeal carcinoma (NPC). Interleukin (IL)-12 and IL-4 are primarily secreted by dendritic cells (DCs) and activated T lymphocytes, respectively; these factors can induce Th cell differentiation and cytotoxic lymphocyte production, both of which facilitate tumors through the STAT4 and STAT6 pathways, respectively. In this study, the relationship between FSTL1 and both IL-12 and IL-4 as well as the functional mechanism of these cytokines was explored...

Optimal doses of Ribavirin (RBV) for hepatitis C virus (HCV) treatment are not known. To assess the safety and efficacy of PegIFNalfa-2a in combination with an adjusted (ADJ) RBV dose based on early pharmacokinetics versus a fixed standard (STD) dose of RBV in chronic HCV genotype (GT) 4-naive patients in a randomized trial. One hundred eighty-one patients were randomized. The baseline variables were similar in both arms and females were 50.3% of the patients, 76.5% had minimal-moderate fibrosis (F0-2). Sustained virologic response (SVR) was achieved in 99 (54...

The 2015-2016 Zika virus (ZIKV) outbreak in the Americas has brought this relatively unknown flavivirus into the spotlight as the etiologic agent of congenital Zika syndrome in newborns and, potentially, of Guillain-Barré syndrome in adults. ZIKV shares a high degree of amino acid sequence homology with the closely related flavivirus Dengue virus (DENV). Due to the paucity of research investigating T cell-mediated immune responses to ZIKV, the precise roles of T cells in protection against and pathogenesis of ZIKV infection are unclear...

Wild birds play a key role in the spread of avian influenza virus (AIV). There is a continual urgent requirement for AIV vaccines to address the ongoing genetic changes of AIV. In the current study, we trialed a novel AIV vaccine against the wild bird source of H5N1 type AIV with recombinant adenovirus expressing granulocyte monocyte colony-stimulating factor (GM-CSF) as an adjuvant. A total of 150-day-old commercial chicks, with AIV-maternal-derived antibody, were divided into 6 groups. The primary vaccination was performed at day 14 followed by a subsequent boosting and intramuscular challenge on day 28 and 42, respectively...

Type I interferons (IFN), including IFN-beta (IFNB), activate multiple STAT signaling to drive various biological responses. Another type I IFN, IFN-tau (IFNT), secreted by ruminant embryonic trophoblast cells, has multiple functions with low cytotoxicity. Here, we examined the effects of IFNT on human trophoblast cell functions. First, we performed next-generation sequencing and demonstrated that IFNT-dependent changes in the human Sw.71 trophoblast cell line are partly mediated by proinflammatory as well as IFN signaling...

Curcumin has shown protective potential on osteoarthritis. However, its effect on treatment of osteoarthritis remains elusive so far. This study aimed to determine whether curcumin could ameliorate osteoarthritis in vivo and the underline mechanisms. The mice subjected to destabilization of the medial meniscus (DMM) surgery were administered curcumin. Cartilage integrity was evaluated by immunohistological staining. Expression levels of inflammatory cytokines from mice arthrodial cartilage were detected. THP-1 cells were primed by lipopolysaccharide (LPS)/ATP to induce inflammation, followed by the addition of curcumin...

Lyme neuroborreliosis (LNB), which is the most common neurological manifestation of Lyme disease (LD), seriously impairs both the central and peripheral nervous systems. Current LNB diagnostic methods and criteria are not very effective. Recently, several studies have indicated that a high concentration of the chemokine CXC ligand 13 (CXCL13) in cerebrospinal fluid (CSF) could be used as a new biomarker for the diagnosis of LNB. Thus, we carried out a meta-analysis to systematically analyze the data from these studies to evaluate the value of CXCL13 as an LNB biomarker...

Rheumatoid arthritis (RA) is a systemic autoimmune disease affecting multiple joints. It remains unclear which factors in the circulation are associated with the systemic spread of the disease. Fibrocytes are pluripotent mesenchymal stem cells present in the circulation of RA patients. Our earlier findings implicated activated fibrocytes in the etiology of onset and pathogenesis of RA. Elevated levels of interleukin-34 (IL-34) in the serum and synovial fluid of RA patients are associated with rheumatoid factor and anticyclic citrullinated peptide antibodies, indicators of RA...

MicroRNAs (miRNAs) are gene expression's important posttranscriptional regulators. The precise function of miRNAs in ulcerative colitis (UC) is not entirely known. Our investigation's aim was to identify miRNAs induced in patients with active UC and to evaluate miR-141 influences on ameliorating intestinal inflammation. The miRNA expression profiles in patients suffering active UC (n = 15) and healthy individuals used as control (n = 13) were assessed adopting miRNA microarrays. Via quantitative real-time polymerase chain reaction, miR-141 expression was confirmed...

Periodontitis is a progressive inflammatory disease initiated by bacterial biofilm adhering to the tooth surface. If left untreated, periodontitis may lead to tooth loss and destruction of the alveolar bone. Regaining the lost alveolar bone is a clinical challenge because of the limited differentiation ability of osteoblasts in inflammatory environments. We have previously shown the anti-inflammatory and antiosteoclastogenic activities of parthenolide (PTL) in human periodontal ligament-derived cells by inhibiting nuclear factor kappa B (NF-κB) signaling, indicating its potential for periodontitis treatment...

Mycobacterium tuberculosis PE/PPE family proteins play a vital role in antigenic diversity, host-pathogen interactions, and immune evasion. As secreted by ESX-5 system, M. tuberculosis PPE27 is related to the growth and virulence of the bacilli. In this study, we expressed PPE27 in the nonpathogenic fast growing Mycobacterium smegmatis. We found that the recombinant strain exhibits higher survival rate under several hostile conditions in vitro and longer persistence in mouse tissues. The survival of the recombinant strains was also enhanced in the mouse macrophage ANA-1, accompanied by higher level of host cell death, higher secretion of tumor necrosis factor-alpha, and a slightly higher amount of interleukin (IL)-1β, which could be abolished by the nuclear factor-κB, p38, and ERK inhibitors...

A mix of flavonoids comprising baicalin (BA) and catechin showed effective impacts on controlling the progress of knee osteoarthritis (OA). However, little is known about the underlying mechanisms. The influences of BA on the transcriptional levels of a series of proinflammatory genes were measured using real-time reverse transcription and polymerase chain reaction (RT-PCR). The expressions of proteins involved in nuclear factor-κB (NF-κB) activation were detected by Western blot. The in vitro results were confirmed in a mouse OA model...

Foxp3+ regulatory T cells (Tregs) play an indispensable role in controlling tolerance and immunity against self- and foreign antigens. The failure of Tregs to properly function is the direct cause of systemic and chronic inflammation as well as immune suppression. It is now evident that Tregs are highly heterogeneous populations depending on the surface phenotypes, cytokine profiles, and anatomical locations. Yet, our understanding of the cellular and molecular pathways underlying such heterogeneity is very limited...

Viral hepatitis is a serious problem worldwide that was under-recognized till recently. The prevalence of chronic hepatitis C virus (HCV) is estimated to be 180 million people worldwide. Treatment of chronic HCV using combined pegylated interferon and ribavirin (PEG/RIBA) has long been the standard of care with modest response. In our study, we will report the real-life experience of serious adverse events (SAEs) that were reported by the National Committee for Control of Viral Hepatitis (NCCVH, Cairo, Egypt) program while treating chronic HCV using the triple therapy, sofosbuvir combined with pegylated interferon and ribavirin (PEG/RIBA/SOF), which led to premature discontinuation of treatment...

Although eradication of hepatitis C virus (HCV) decreases the risk of hepatocellular carcinoma (HCC) development, a considerable level of risk remains in cirrhotic patients with advanced liver disease. Yet, data for the effect of serum markers on HCC development in this population after viral eradication are still lacking. Seventy-eight consecutive patients with HCV infection and decompensated cirrhosis were administered interferon-based regimens at our hospital between August 2008 and December 2013. Thirty-four achieved sustained virological response and were enrolled in the study...

Genome-wide association studies discovered interferon lambda (IFNL or IFN-λ) locus on chromosome 19 to be involved in clearance of chronic hepatitis C virus (HCV) infection in patients following interferon-α-ribavirin (IFN-RBV) therapy. Subsequent studies established a dinucleotide polymorphism rs368234815, as the prime causal variant behind this association. The ΔG allele of this variant gives rise to a new IFNL gene, IFNL4, coding for IFN-λ4 whose activity paradoxically associates with lesser viral clearance rates...

Tissue inhibitor of metalloproteinase-1 (TIMP-1) is a protein implicated in the control of inflammation in a number of autoimmune diseases. We hypothesized that the balance of TIMP-1 and matrix metalloproteinase-9 (MMP-9) may influence the control or perpetuation of inflammation in corticosteroid-responsive (RES) and corticosteroid-resistant (NR) autoimmune inner ear disease (AIED) patients. In the present study, we observed that plasma from AIED patients exhibited greater levels of TIMP-1 values compared with normal healthy controls...
