Circadian Rhythms of Endothelial Nitric Oxide Synthase and Toll-like Receptors 2 Production in Females with Rheumatoid Arthritis Depending on NOS3 Gene Polymorphism

Background: Rheumatoid Arthritis (RA) is an autoimmune polygenic disease characterized by rapid disability progression and high prevalence. Progression of RA is closely associated with chronobiological changes in the production of some hormones and inflammatory mediators, influencing the disease course and therapy efficacy. The main pathogenetic mechanism of RA is angiogenesis, which is controlled by biological clock-genes. Further investigation...
