Pattern recognition receptor (PRR) agonists are promising for use in modulating immune responses in clinical settings characterized by immune immaturity or deficiency. β-Glucans derived from Ganoderma lucidum have demonstrated immune-modulatory activity both in vitro and in vivo. To evaluate the immunomodulatory activity of orally administered β-glucans, a randomized, double-blinded, placebo-controlled clinical study was performed in asymptomatic children, aged 3 to 5 years old, from Medellin, Colombia. Primary outcomes were the circulating CD8+ T lymphocyte and natural killer cell counts; secondary outcomes were circulating lymphocyte counts (total, CD3+, and CD4+ T cells), serum concentrations of total immunoglobulin A and cytokines, and various hematological parameters...

Multiple myeloma remains an incurable disease, and continued efforts are required to develop novel agents and novel drug combinations with more effective anti-myeloma activity. Here, we show that the pan-PIM kinase inhibitors SGI1776 and CX6258 exhibit significant anti-myeloma activity and that combining a pan-PIM kinase inhibitor with the immunomodulatory agent lenalidomide in an in vivo myeloma xenograft mouse model resulted in synergistic myeloma cell killing without additional hematologic or hepatic toxicities...

Over the past few years, exosomes, a class of extracellular vesicles (EVs), have emerged as key players for inter-cellular communication ultimately modulating the behavior of target cells with countless outcomes. Nevertheless, the potential role of exosomes as vaccine adjuvants remains largely unexplored. Herein, we hypothesized that exosomes derived from immune cells may have an immunostimulatory effect and could constitute a good target towards the development of new fine-tuned vaccine adjuvants. To accomplish this goal, exosomes isolated from lipopolysaccharide endotoxin (LPS)-stimulated human monocytic cell line (THP-1) were characterized and tested for their non-specific immunostimulatory activity when administered subcutaneously to healthy mice; additionally, exosomes' vaccine adjuvant ability was also disclosed after their inclusion in vaccine formulations...

Lycium barbarum polysaccharides (LBP) are major bioactive constituents of wolfberry which possess several pharmacological effects such as antioxidant and immunomodulatory activities. We aimed to evaluate how LBP attenuated the hepatic injury in a non-alcoholic steatohepatitis (NASH) methionine-choline deficient (MCD) mouse model. NASH was induced in C57BL/6N mice by feeding with MCD diet for 6 weeks. During the experiments, 1 mg/kg LBP was intragastrically fed on a daily basis with or without MCD diet lasting from the 4th to 6th week...

BACKGROUND/AIMS: Tumor necrosis factor-α (TNF-α) inhibitors and ustekunimab are widely used in autoimmune diseases. It is known that these biological agents cause the reactivation of hepatitis B virus (HBV). There is no standardized strategy to prevent the reactivation in patients with evidence of a previous HBV infection. In our study, anti-HBc IgG-positive patients who received a biological agent were evaluated in terms of HBV reactivation. MATERIALS AND METHODS: Patients who were followed up for the use of biological agents in our clinic were evaluated retrospectively...

Environmental pollutants, particularly lead, pose a serious threat to human and animal health that causes disturbances of several functions, including hepatotoxicity. Therefore, the search for a new treatment that could safely and effectively block or reverse liver injuries remains a challenge. This study was carried out to investigate the protective efficacy of Juglans regia vegetable oil (JRVO) against the hepatotoxicity induced by lead. To achieve this aim, adults male rats were treated for 10 days with Pb (0...

The rabbit caliciviruses Lagovirus europaeus GI.1 and GI.2 both cause acute necrotizing hepatitis in European rabbits ( Oryctolagus cuniculus ). Whilst GI.2 is highly virulent in both young and adult rabbits, rabbits younger than eight weeks of age are highly resistant to disease caused by GI.1, although they are still permissive to infection and viral replication. To investigate the underlying mechanism(s) of this age related resistance to GI.1, we compared liver transcriptomes of young rabbits infected with GI...

Zinc oxide nanoparticles (ZnONPs) are being used extensively in manufacturing skin lotions and food products and in various biological and pharmaceutical industries because of their immunomodulatory and antimicrobial properties. In this study, ZnONPs were synthesized by a precipitation method and characterized by X-ray diffraction (XRD) techniques, scanning electron microscopy (SEM), and ultraviolet-visible spectroscopy to investigate their structural, morphological, and optical properties. For in vivo evaluation, 40 healthy albino mice were randomly allocated to four equal groups among which the first one was the control group, while the second, third, and fourth were treated with carbon tetrachloride (CCl4 ), a blend of CCl4 and ZnONPs, and ZnONPs alone, respectively, for 21 days...

Virus-infected cells can regulate non-permissive bystander cells, but the precise mechanisms remain incompletely understood. Here we report that this process can be mediated by transfer of viral RNA-loaded exosomes shed from infected cells to myeloid-derived suppressor cells (MDSCs), which in turn regulate the differentiation and function of T cells during viral infection. Specifically, we demonstrated that patients with chronic hepatitis C virus (HCV) infection exhibited significant increases in T follicular regulatory (TFR ) cells and decreases in T follicular helper (TFH ) cells...

Introduction: Hepatic cancer is a highly lethal tumour with increasing worldwide incidence. These tumours are characterized by the proliferation of malignant cells, generalised immunosuppression and chronic inflammation marked with an increase in inflammatory markers as a neutrophil-to-lymphocyte ratio (NLR), the platelet-to-lymphocyte ratio (PLR) and overexpression of CD4+CD39+ on T lymphocytes. The studies have outlined immunomodulatory changes in liver cancer patients as the plausible explanation for the better survival...

Lithium is the smallest monovalent cation with many different biological effects. Although lithium is present in pharmacotherapy of psychiatric illnesses for decades, its precise mechanism of action is still not clarified. Today lithium represents first-line therapy for bipolar disorders (because it possesses both antimanic and antidepressant properties) and the adjunctive treatment for major depression (due to its antisuicidal effects). Beside, lithium showed some protective effects in neurological diseases including acute neural injury, chronic degenerative conditions, Alzheimer's disease as well as in treating leucopenia, hepatitis and some renal diseases...

Estrogenic endocrine disrupting chemicals (EEDCs) are present ubiquitously in sediments and aquatic ecosystems worldwide. The detrimental impact of EEDCs on the reproduction of wildlife is widely recognized. Increasing evidence shows the immunosuppressive effects of EEDCs in vertebrates. Yet, no studies have considered concomitantly EEDC-induced impacts on reproductive impairment and immune suppression in vivo, which are deemed essential for risk assessment and environmental monitoring. In this study, EE2 was used as a representative EEDC, for parallel evaluation of EEDC-induced immune suppression (immune marker gene expression, leukocyte numbers, host resistance assay, and immune competence index) and reproductive impairment (estrogen responsive gene expression, fecundity, fertilization success, hatching success, and reproductive competence index) in an established fish model (marine medaka Oryzias melastigma), considering sex-specific induction and adaptation and recovery responses under different EE2 exposure scenarios...

Interferon lambda (IFN-λ) is a relatively unexplored, yet promising anti-viral agent. IFN-λ has recently been tested in clinical trials of chronic hepatitis B virus infection (CHB), with the advantage that side effects may be limited compared with IFN-α, as IFN-λ receptors are found only in epithelial cells. To date, IFN-λ's downstream signaling pathway remains largely unelucidated, particularly via proteomics methods. Here, we report that IFN-λ3 inhibits HBV replication in HepG2.2.15 cells, reducing levels of both HBV transcripts and intracellular HBV DNA...

Background: Hepatitis C (HCV) is known as a serious blood-borne disease that infects millions of people globally. NS3 is a conserved non-structural sequence of hepatitis C virus which has a major role in activating specific CTL responses. As known, there is no effective vaccine against HCV infection, thus it is required to design a specific regimen of vaccination. Recently, the strong immunological properties of Heat shock proteins (Hsps) led to their use as immunomodulators and an antigen carrier for subunit vaccine candidates...

Sarcoidosis is a multisystem inflammatory disease, which is characterized by the development of noncaseating granulomas amid healthy tissue. While most commonly affecting the mediastinum and/or lungs, sarcoid can also affect the liver, resulting in "hepatic sarcoid." The spectrum of disease in hepatic sarcoid is variable, ranging from asymptomatic or mild liver enzyme abnormalities to end-stage liver disease requiring liver transplantation. Because clinically-significant hepatic sarcoid is rare, research on epidemiology, clinical manifestations, and treatment is limited...
