Genetic factors have been shown to be associated with Myelodysplastic syndromes (MDS) susceptibility. In recent years, the role of inflammation in the promotion of tumor growth is supported by a broad range of experimental and clinical evidence. But the relationship between polymorphisms in NOD-like receptor protein 3 (NLRP3) inflammasome and MDS is rarely reported. Thus, we conducted a case-control study, and genotyped five single nucleotide polymorphisms (SNPs) (NLRP3, IL-1β, IL-18, CARD8, and NF-κB) in MDS patients and healthy controls...

Cardiovascular diseases as atherosclerosis are associated to an inflammatory state of the vessel wall which is accompanied by endothelial dysfunction, and adherence and activation of circulating inflammatory cells. Hydrogen sulfide, a novel cardiovascular protective gaseous mediator, has been reported to exert anti-inflammatory activity. We have recently demonstrated that the SH containing ACE inhibitor zofenoprilat, the active metabolite of zofenopril, controls the angiogenic features of vascular endothelium through H2S enzymatic production by cystathionine gamma lyase (CSE)...

Rheumatoid arthritis (RA) is a systemic autoimmune disease that results in a chronic and inflammatory disorder. Dynamic balance of helper T cells (Th)1, Th17 and regulatory T cells (Treg) is broken in RA. Since there is no cure for RA at present, it's necessary to find a truly effective and convenient treatment. Several studies intended to induce ergotopic regulation to treat autoimmune diseases. This study was undertaken to find the potential ergotope peptides and investigate its effect in treating the animal model of RA and their underlying regulatory mechanisms...

Zerumbone is a sesquiterpene present in Zinger zerumbet. Many studies have demonstrated its marked anti-inflammatory and anti-carcinogenesis activities. Recently, we showed that zerumbone binds to numerous proteins with scant selectivity and induces the expression of heat shock proteins (HSPs) in hepatocytes. To dampen proteo-toxic stress, organisms have a stress-responsive molecular machinery, known as heat shock response. Heat shock factor 1 (HSF1) plays a key role in this protein quality control system by promoting activation of HSPs...

Asthma is a heterogeneous disease characterized by chronic airway inflammation. CD4(+) T-helper 9 (Th9) cells are closely linked to asthma, helping to regulate inflammation and immunity. Epidemiological studies showed that mycobacteria infections are negatively associated with asthma. Our previous research showed that inactivated Mycobacterium phlei nebulization alleviated the airway hyperresponsiveness and inflammation of asthma. However, the relationship between Th9 cells and mycobacteria remains unknown...

Interlukin-6 (IL-6) is a multifunctional cytokine produced by several cell types that has a role in fibrosis. Fibroblasts (FBs) maintain this underlying pathogenic change through regulation of IL-6 production; however, its potential functional role in regulating surrounding cellular structural changes during ischemic myocardial remodeling remains unexplored. Here, we generated FBs, cardiomyocytes (CMs), and blood vascular endothelial cells (ECs) from the ventricles of neonatal rats. IL-6 was then overexpressed in FBs and the cells were treated with IL-6 receptor inhibitor (IL6RI), TGF-β1 receptor inhibitor (TβRI), or MMP2/MMP9 inhibitor (MMPI) using monoculture or coculture models under hypoxic conditions...
