Relation between microRNA-155 and inflammatory mediators in multiple sclerosis.

Multiple sclerosis (MS) is a complex autoimmune condition affecting the central nervous system characterized by axonal damage, demyelination, and chronic inflammation. Multiple molecular and cellular components mediate neuroinflammation in MS. In human macrophages and microglia, miRNA-155 is an essential proinflammatory noncoding RNA that regulates phenotypic and functional polarization properties.

Possible role of rice bran extract in microglial modulation through PPAR-gamma receptors in alzheimer's disease mice model.

Alzheimer's Disease (AD), the most prevalent neurodegenerative disorder among elderly people, is ordinarily associated with progressive cognitive decline. Peroxisome proliferator-activated receptors-gamma (PPAR-γ) agonists can be targeted as a beneficial therapeutic strategy against AD. In the present study, we aimed to investigate the preventive and therapeutic effects of rice bran extract (RBE) as a possible PPAR-γ agonist on the microglial phenotype modulation in AD in mice compared to the effects of pioglitazone.

Association of Angiotensin-Converting Enzyme (ACE) Gene Polymorphism with Inflammation and Cellular Cytotoxicity in Vitiligo Patients.

Background: Vitiligo is a disorder with profound heterogeneity in its aetio-pathophysiology. Angiotensin converting enzyme (ACE) plays an important role in the physiology of the vasculature, blood pressure and inflammation. An insertion/deletion (I/D) polymorphism of the ACE gene was reported be associated with the development of vitiligo.

Osteopontin gene polymorphisms as predictors for the efficacy of interferon therapy in chronic hepatitis C Egyptian patients with genotype 4.

This study aimed to determine the relationship between osteopontin gene polymorphisms and its protein level and the efficacy of interferon-based therapies in Hepatitis C virus (HCV) patients. Hundreds HCV patients genotype 4, treated with pegylated interferon alfa-2b plus ribavirin and 60 healthy subjects were enrolled. All individuals were subjected to clinical and laboratory parameters, including hepatitis markers and HCV quantitation by real-time polymerase chain reaction.
