Ankylosing spondylitis (AS) is a debilitating chronic inflammatory disease with genetic predisposition, which is characterized by the involvement of spine and sacroiliac joints. Due to the relatively unsuccessful treatments, we designed β-D-mannuronic (M2000) with the beneficial effects in various experimental models as a novel non-steroidal anti-inflammatory drug (NSAID). The aims of our present study were: first, to compare the therapeutic effects of M2000, as a novel designed NSAID, with naproxen and placebo in Iranian patients with AS during 12 weeks; second, to evaluate the effect of M2000 on gene expression of cyclooxygenase enzyme (COX-1/COX-2), a key enzyme in the initiation of inflammatory pathways in AS patients; and third, to assess the activity of COX-1 and COX-2 enzymes in the presence/absence of M2000 at the different doses in the murine macrophage, J774 cell line...

Gout is a disorder that triggers a severe inflammatory reaction which generates episodes of intense pain and discomfort to the patient. Arctium minus (Hill) Bernh. (Asteraceae) is known as "burdock" and displays anti-inflammatory, antinociceptive, against rheumatic pain and radical-scavenging activities. Species of the genus Arctium have been used in assistant therapy of gout and other inflammatory processes. We investigated the antinociceptive and anti-edematogenic effects of the crude extract of A. minus seeds in an acute gout attack model induced by intra-articular injection of monosodium urate (MSU) crystals in adult male Swiss mice (25-30 g)...

Various investigations have demonstrated that human fibroblast-like synoviocytes rheumatoid arthritis (HFLS-RA) take part in the chronic inflammatory responses and RA progression. Inhibition of synovium activation and inflammatory processes may represent a therapeutic target to alleviate RA. Paeonol, a major natural product, has many biological and pharmacological activities. However, its protective effects against RA considering HFLS-RA have not been explored. In this study, anti-inflammatory effects of paeonol were detected in interleukin-1β (IL-1β)-treated HFLS-RA...

Pulmonary fibrosis is a result of an abnormal wound healing in lung tissue triggered by an excessive accumulation of extracellular matrix proteins, loss of tissue elasticity, and debit of ventilatory function. NKT cells are a major source of Th1 and Th2 cytokines and may be crucial in the polarization of M1/M2 macrophages in pulmonary fibrogenesis. Although there appears to be constant scientific progress in that field, pulmonary fibrosis still exhibits no current cure. From these facts, we hypothesized that NKT cells could influence the development of pulmonary fibrosis via modulation of macrophage activation...

Hydrogen sulfide (H2S) is an endogenous mediator that contributes to many important physiological processes including vasodilation and vascular smooth muscle relaxation; in turn, preventing tissue damage and reducing inflammation. Heme oxygenase (HO) enzymes, of which HO-1 is inducible by harmful stimuli, were found to regulate intestinal inflammation in experimental animal models of colitis. We aimed to investigate the protective effects of H2S against 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced colitis in rats, and whether HO enzyme system is involved in the H2S-induced colonic cytoprotection...

Alveolar macrophages are key contributors to both the promotion and resolution of inflammation in the lung and are categorized into pro-inflammatory (M1) and anti-inflammatory (M2) phenotypes. The change in M1/M2 balance has been reported in various pulmonary diseases and is a target for therapeutic intervention. The aim of this study was to assess the modulation of M1/M2 phenotype in alveolar macrophages by water-soluble carbon monoxide-releasing molecule-3 (CORM-3). Rat alveolar macrophages (AM) (NR8383) in culture were stimulated with LPS (5 ng/ml)/IFN-γ (10 U/ml) or IL-4 (10 ng/ml)/IL-13 (10 ng/ml) to induce M1 and M2 phenotypes, respectively...

Alendronate (ALD), one among the nitrogen-containing bisphosphonates (NBPs), is currently used for the treatment of many pathological conditions. Unfortunately, although generally tolerated, NBPs treatment has been associated with central nervous system (CNS) adverse outcomes, such as amnesia, hallucinations and visual disturbances. So, we analyzed the effect of ALD treatment in glial cells, the main sources of cholesterol for neurons and principal cells involved in the immunological defense of the brain. We treated a glial cell line (U87-MG) with increasing doses of ALD (0...
