According to the original hypothesis, synovial tissue (ST) oedema and synovial fluid (SF) volume increase contribute to local hypoxia and metabolic alterations and to inflammation (A 1). Studies on biochemical mechanisms (A 2) in synovitides show that the SF volume correlates to SF hypoxia that
Acute ruminal acidosis (ARA) is the result of increased intake of highly fermentable carbohydrates, which frequently occurs in dairy cattle and is associated with aseptic polysynovitis. To characterise the metabolic changes in the joints of animals with ARA, we performed an untargeted gas
The rheumatoid joint is hypoxic. The loss of the physiologic defense mechanism, reflex muscle inhibition, allows the generation of high intraarticular pressures, particularly during exercise. Hypoxia alters the biochemistry of the synovium and encourages the production of reactive oxygen species
Hypoxia may contribute to the pathogenesis of synovitis in rheumatoid arthritis (RA). Magnetic resonance spectroscopy (MRS) is a technique that uses radiofrequency waves to generate a signal which allows a qualitative and quantitative assessment of the biochemical composition of tissue. MRS was used
Human cohort studies have demonstrated a role for systemic metabolic dysfunction in osteoarthritis (OA) pathogenesis in obese patients. To explore the mechanisms underlying this metabolic phenotype of OA, we examined cartilage degradation in the knees of mice from different genetic backgrounds in
The intraperitoneal injection of peptidoglycan-carbohydrate fragments from Group A streptococci produces a chronic, polyarticular, erosive synovitis in rats. The cell wall material accumulates rapidly in the liver, spleen, and lymph nodes, where it causes little injury. At the same time, selective
We examined the efficacy of the culture filtrate of Cryptococcus neoformans var. gattii (CneF) as a novel anti-inflammatory compound in experimental septic arthritis. Haematogenously infectious arthritis was induced in rats by a single intravenous injection of 109 CFU Staphylococcus aureus producing
Trying to surpass host defenses, fungal infections alter the immune response. Components from nonpathogenic fungi present therapeutic anti-inflammatory and immunomodulating activities. This study reveals that proteins present in a Coccidioides posadasii extract provide anti-inflammatory benefit in
We have recently shown that synoviocytes and extracellular matrices exhibit distinct patterns of carbohydrate expression. Their biological relevance is however not known. The purpose of the present study was to find out whether human synovial tissue would also show a specific receptor pattern for
Some tumor-associated antigens (TAAs) are expressed on inflammatory cells. We previously detected carcinoembryonic antigen (CEA; CD66) in the rheumatoid (RA) synovium. The production of CEA, CA19-9, CA125, and CA15.3, may be increased in patients with RA, scleroderma, lupus, and Sjögren's syndrome
BACKGROUND
Acute ruminal acidosis (ARA) is a metabolic disease of cattle characterized by an aseptic
synovitis. ARA is the result of an increased intake of highly fermentable
carbohydrates that frequently occurs in dairy cattle subjected to high production requirements. In human
OBJECTIVE
Epidemiological and experimental studies have established obesity to be an important risk factor for osteoarthritis (OA), however, the mechanisms underlying this link remains largely unknown. Here, we studied local inflammatory responses in metabolic-OA.
METHODS
Wistar rats were fed with
Rheumatoid arthritis (RA) is characterized by chronic inflammatory synovitis resulting in progressive joint destruction. Persistent synovial inflammation is induced by activation of various inflammatory cells. G‑protein‑coupled bile acid receptor 1 (TGR5) is a G‑protein‑coupled receptor activated by
