Penconazole is a widely used fungicide that is toxic to a variety of organisms including fish. In the present study, we investigated the developmental toxicity of penconazole on zebrafish embryos by exposing to different concentrations of penconazole (0.8, 1.6 and 2.4 mg/L) from 4-h post-fertilization (hpf). Hatching, survival, and heart rates, body length, malformation and expression of several genes were detected. The results showed that penconazole exposure induced developmental toxicity, including delayed hatching, reduced survival, and heart rate...

SP100 proteins are components of nuclear domain 10 structures and have been implicated as inhibitors of human papillomavirus (HPV) replication. In this study, we have addressed the role of SP100 in tumour formation by the cottontail rabbit (Sylvilagus floridanus) papillomavirus (CRPV or SfPV1) in a rabbit model. Tissue culture studies using rabbit keratinocyte lines indicated that rabbit SP100 is an interferon-beta-inducible gene similar to its human counterpart. Stable knockdown of SP100 by shRNA in a cell line harbouring CRPV genomes resulted in a decrease of viral early transcripts...

Apoptosis and programmed necrosis (necroptosis) determine cell fate, and antagonize infection. Execution of these complementary death pathways involves the formation of receptor-interacting protein kinase 1 (RIPK1) containing complexes. RIPK1 binds to adaptor proteins, such as TRIF (Toll-IL-1 receptor-domain-containing-adaptor-inducing interferon-beta factor), FADD (Fas-associated-protein with death domain), NEMO (NF-κB regulatory subunit IKKγ), SQSTM1 (sequestosome 1/p62), or RIPK3 (receptor-interacting protein kinase 3), which are involved in RNA sensing, NF-κB signaling, autophagosome formation, apoptosis, and necroptosis...

Primary biliary cirrhosis (PBC) is an autoimmune liver disease. Its histological characteristics, such as progressive intrahepatic bile duct destruction, cholestasis, and liver cirrhosis, are caused by the body's autoimmune disorders. Interleukin (IL)-35 has two subunits (p35 and Ebi3) and is a member of the IL-12 family of heterodimeric cytokines. IL-35 has immunosuppressive functions and plays an important role in many autoimmune diseases. In this study, we compared plasma levels of IL-35 and relative mRNA expression levels of p35 and Ebi3 in peripheral blood mononuclear cells (PBMCs) from 70 PBC patients and 70 healthy individuals...

BACKGROUND: IgG4-related disease often forms a mass and the affected lesion is clinically removed because the mass cannot be differentiated from a neoplasm. Affected lesions commonly occur in the pancreas, hepatobiliary tract, kidney, and retroperitoneum. However, the lesion rarely occurs in the thymus. A histological worldwide consensus of IgG4-related disease proposed that pathological diagnosis of IgG4-related disease should meet more than two of three major features: 1) dense lymphoplasmacytic infiltration with greater than 40% IgG4+/IgG+ plasma cells, 2) storiform fibrosis; and 3) obliterative phlebitis...

Persistent high-risk human papillomavirus (HPV) infection is the major causal factor in cervical and other anogenital cancers. Because there are currently no therapeutics capable of preventing neoplastic progression of HPV infections, understanding the mechanisms of HPV-mediated persistence, including immune evasion, is a major research priority. The multifunctional growth factor transforming growth factor beta (TGFβ) has been shown to inhibit expression of early viral transcripts from cells harboring integrated HPV genomes or cells infected with retroviruses expressing HPV oncoproteins...

Depressive disorders are common in patients with multiple sclerosis, influencing their quality of life and adherence to treatments, as well as becoming more frequent with the progression of the disease and in the secondary progressive form of multiple sclerosis. Patients with multiple sclerosis often experience a typical cluster of symptoms in association with depression, such as fatigue, pain and cognitive impairment. However, the pathogenesis of multiple sclerosis-related depression remains partially unclear, even though genetic, immune-inflammatory and psychosocial factors might be seen to play a role, in addition to the brain structural alterations documented by magnetic resonance imaging studies...

Human type I interferons are a family of pleiotropic cytokines with antiviral, anti-proliferative and immunomodulatory activities. They signal through the same cell surface receptors IFNAR1 and IFNAR2 yet evoking markedly different physiological effects. One differentiating factor of interferon-beta (IFN-β) from other type I interferons is the presence of theAsn-Gly-Arg (NGR) sequence motif, which, upon deamidation, converts to Asp-Gly-Arg (DGR) and iso-Asp-Gly-Arg (iso-DGR) motifs. In other proteins, the NGR and iso-DGR motifs are reported as CD13- and αvβ3, αvβ5, αvβ6, αvβ8 and α5β1 integrin-binding motifs, respectively...

It has previously been shown that genital tract infection with Neisseria gonorrhoeae in mice does not induce a state of protective immunity against reinfection but instead suppresses the development of adaptive immune responses against N. gonorrhoeae dependent on transforming growth factor beta (TGF-β) and interleukin 10 (IL-10). Intravaginal administration during gonococcal infection of IL-12 encapsulated in biodegradable microspheres (IL-12/ms) reverses the immunosuppression and promotes the production of gamma interferon (IFN-γ) and of specific antibodies in serum and genital secretions and accelerates clearance of the infection...

Background: Patients increasingly benefit from immunosuppressive/immunomodulatory medications for a range of conditions allowing them a lifestyle similar to healthy individuals, including travel. However, the administration of live vaccines to immunodeficient patients bears the risk of replication of the attenuated vaccine microorganism. Therefore, live vaccines are generally contraindicated on immunosuppression. Data on live vaccinations on immunosuppressive/immunomodulatory medication are scarce...

Atherosclerosis (AS) is the main cause of cardiovascular diseases. This study investigated Yirui (YR) capsules, whose ingredients are available in health food stores, against AS and the underlying mechanisms. Male apolipoprotein E-deficient mice fed a high-fat diet for 10 weeks developed severe aortic lesions, but YR significantly decreased the plaque area in the total aorta and aortic root. YR affected the serum lipid profile by significantly reducing total cholesterol, low-density lipoprotein cholesterol (LDL-C), triglyceride (TG), and oxidative modification of LDL-C (Ox-LDL) levels...

Although multiple sclerosis (MS) remains incurable, interferon beta (IFNβ) has been at the forefront of treatment for many years. Different formulations of IFNβ allow for different levels of exposure: low-dose/frequency with some agents, and high-dose/frequency with others. Areas covered: This review article discusses existing and emerging efficacy and safety data for IFNβ in MS. Clinical evidence of IFNβ efficacy has been generated and accumulated over many decades. During this time, key clinical trials have demonstrated the benefits of high-dose and/or high-frequency dosing of IFNβ-1a or β-1b, compared with lower levels of exposure, on outcome measures such as relapse rates, disability progression, disease progression and magnetic resonance imaging lesion outcomes...
