Severe Plasmodium falciparum malaria anemia (SMA) is a major cause of mortality in pediatric wards. Variations in inflammatory mediator production play an essential role in disease outcomes. Indeed, several studies have shown the involvement of pro- and anti-inflammatory cytokines such as IFN-γ, IL-6, TNF-α and IL-10 in malaria immunopathology. In other hand the exact role of Th17 cytokines such as IL-17, IL-22 and IL-21 in malaria remains poorly documented. Here, we investigated IFN-γ, TNF-α, IL-6, IL-12, IL-10, IL-4, IL-13, IL-17, IL-22 and IL-21 circulating levels and their association with malaria anemia and parasitemia in Gabonese children...

Coenzyme Q10, (CoQ10) an electron transporter and an antioxidant, protects a variety of cell types against oxidative stress and apoptosis. However, protective effect of CoQ10 on oxidative stress-induced apoptosis in lymphocytes has not been studied in detail. In this study, we investigated the effect of CoQ10 on oxidative stress-induced apoptosis in lymphocytes. An exposure of peripheral blood lymphocytes to oxidative stressors, rotenone or hydrogen peroxide, lead to apoptosis. Pre-treatment of lymphocytes with CoQ10 resulted in a significantly reduced level of oxidative stress-induced apoptosis, which was associated with decreased reactive oxygen species production, an inhibition of mitochondrial membrane depolarization, and inhibition of activation of caspase-9 and caspase-3...

Exposure to ambient ozone causes airway hyperreactivity and lung inflammation, which represent an important health concern in humans. Recent clinical and experimental studies contributed to the understanding of the mechanisms of epithelial injury, inflammation and airway hyperreactivity, which is reviewed here. The present data suggest that ozone induced oxidative stress causes inflammasome activation with the release of IL-1, other cytokines and proteases driving lung inflammation leading to the destruction of alveolar epithelia with emphysema and respiratory failure...

Lung cancer is the most commonly diagnosed cancer as well as the leading cause of cancer-related deaths worldwide. To date, surgery is the first choice treatment, but most clinically diagnosed cases are inoperable. While chemotherapy and/or radiotherapy are the next considered options for such cases, these treatment modalities have adverse effects and are sometimes lethal to patients. Thus, new effective strategies with minimal side effects are urgently needed. Cancer immunotherapy provides either active or passive immunity to target tumors...

Many inflammatory chemokines release from leukocytes and pancreatic acinar cells which play important roles in pathophysiology of acute pancreatitis (AP). Of interests, CXCL2 and CCL2 have been shown elevated in the plasma of patients with AP. We have recently found that Glycyrrhizin (GZ) attenuates AP in mice model. In this study, we aimed to investigate the direct effect of GZ on expression levels of CCL2 and CXCl2 in isolated pancreatic acinar cells. Isolated acinar cells were isolated from the pancreas of healthy C57BL/6 mice, stimulated with cerulein (10(-7) M) and then treated with either PBS or different doses of GZ...

MS is an autoimmune disease and interleukin 13 (IL-13) has been proposed to be an important neuroprotective mediator in MS. Because of plausible effect of single nucleotide polymorphisms (SNPs) in expression level or biological activity of any cytokine, we sought to investigate association of IL-13 SNPs, C-1112T, A-1512C and G+2044A, with risk to MS. Sixty-eight RRMS patients and 110 healthy controls were involved in this study. After extraction of genomic DNA, frequency of genotypes and alleles were determined by PCR-RFLP and data were analyzed statistically...

Post-translational protein modifications are a dynamic method of regulating protein function in response to environmental signals. As with any cellular process, T cell receptor (TCR) complex-mediated signaling is highly regulated, since the strength and duration of TCR-generated signals governs T cell development and activation. While regulation of TCR complex-mediated signaling by phosphorylation has been well studied, regulation by ubiquitin and ubiquitin-like modifiers is still an emerging area of investigation...

G protein signaling modulator-3 (GPSM3), also known as G18 or AGS4, is a member of a family of proteins containing one or more copies of a small regulatory motif known as the GoLoco (or GPR) motif. GPSM3 interacts directly with Gα and Gβ subunits of heterotrimeric G proteins to regulate downstream intracellular signals initiated by G protein coupled receptors (GPCRs) that are activated via binding to their cognate ligands. GPSM3 has a selective tissue distribution and is highly expressed in immune system cells; genome-wide association studies (GWAS) have recently revealed that single nucleotide polymorphisms (SNPs) in GPSM3 are associated with chronic inflammatory diseases...

Overexpression of Interleukin-17 (IL-17) family has been shown in a variety of autoimmune diseases. IL-25 (IL-17E), as a member of this family of cytokines, induces the overexpression of IL-13 and impedes Th17/IL-17 responses. In the present study potential single nucleotide polymorphisms (SNP) of IL-25, its serum level in Multiple Sclerosis (MS) patients have been surveyed. Blood samples were obtained from 100 Relapsing-Remitting MS cases, and 100 healthy controls. Serum levels of IL-25 were measured by ELISA...

Human sex determining region Y-box 2 (SOX2) is an important transcriptional factor involved in the pluripotency and stemness of human embryonic stem cells. SOX2 plays important roles in maintaining cancer stem cell activities of melanoma and cancers of the brain, prostate, breast, and lung. SOX2 is also a lineage survival oncogene for squamous cell carcinoma of the lung and esophagus. Spontaneous cellular and humoral immune responses against SOX2 present in cancer patients classify it as a tumor-associated antigen (TAA) shared by lung cancer, glioblastoma, and prostate cancer among others...

Asthma is a chronic lung disease that affects people of all ages and is characterized by high morbidity. The mechanisms of asthma pathogenesis are unclear, and there is a need for development of diagnostic biomarkers and greater understanding of regulation of inflammatory responses in the lung. Post-transcriptional regulation of cytokines, chemokines, and growth factors by the action of microRNAs and RNA-binding proteins on stability or translation of mature transcripts is emerging as a central means of regulating the inflammatory response...

Multiple sclerosis (MS) is a chronic demyelinating immune-mediated disease of the central nervous system. Infections have been implicated in different aspects of the disease such as induction of relapses and possibly, progression. Bladder dysfunction and associated urinary tract colonization (UTC) and infections (UTIs) are common in MS patients. UTIs can exacerbate neurological symptoms in MS, whilst high-dose steroid treatment of acute neurological worsening with concurrent untreated UTC may lead to unmasking of infection...
