Expression of cyclooxygenase-1 and -2 in rheumatoid arthritis synovium.

The aim of this study was to investigate the expression and localization of cyclooxygenase-1 and -2 (COX-1 and COX-2) in synovial tissues from patients with rheumatoid arthritis (RA). Synovial tissues from 9 patients with RA and 5 patients with osteoarthritis (OA) were examined for COX-1 and COX-2 expressions by immunohistochemical staining using 2 polydonal COX-1 and COX-2 antibodies. In RA sy...

The Synovium in Rheumatoid Arthritis

Rheumatoid arthritis (RA) is a chronic autoimmune disease targeting multiple joints. The synovium is the primary site of the inflammatory process, which if untreated leads to irreversible damage to the adjacent cartilage and bone. It is now well established that autoantibodies that are characteristic of RA, including rheumatoid factor (RF) and anti-citrulluninated protein antibodies (ACPA), are...

Expression of IGF-1, IL-27 and IL-35 Receptors in Adjuvant Induced Rheumatoid Arthritis Model

Background: IGF-1 and certain other cytokines have been shown to exert inflammatory/anti-inflammatory roles in chronic joint diseases. Objective: To assess the effect of IGF-1, IL-27 and IL-35, their interaction and their receptor expression in a rheumatoid arthritis model. Methods: Freund’s adjuvant-induced chronic joint inflammation was operated on 160 male rats. Animals were divided into his...

Evaluation of Beclin-1 and Atg5 genes expression levels in peripheral blood cells of patients with rheumatoid arthritis

Background: Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease, which primarily affects the joints. During RA development, T cells and other immune cells are recruited to the synovial tissue and promote RA. Autophagy is a process in which intracellular organelles and compounds are degraded. Autophagy as a regulator of cell homeostasis can affect immune cells activation and c...

TREM-1 expression is increased in the synovium of rheumatoid arthritis patients and induces the expression of pro-inflammatory cytokines.

OBJECTIVES To investigate the expression and function of triggering receptor expressed on myeloid cells-1 (TREM-1) in the synovium of human RA patients as well as the level of soluble TREM-1 in the plasma of RA patients. METHODS Twenty-four RA synovial samples were analysed by gene expression oligonucleotide microarrays. Expression levels of TREM-1 mRNA in murine CIA paws were determined by q...
