OBJECTIVE To investigate the relationship between NLRP3 and the pathogenesis of collagen-induced arthritis. METHODS We used the collagen-induced arthritis (CIA) mouse model. The mice were divided into two groups: the model group (CIA, n = 16) and the control group (Normal, n = 8). The mice were sacrificed seven weeks after immunization. The arthritis score and imaging evaluation (X-rays, Micr...

Novel therapies for rheumatoid arthritis aiming at intervention in the inflammatory process by manipulation of autoreactive T and B lymphocytes receive major interest. However, the development of such therapies is largely hampered by the lack of knowledge of self-Ags recognized during the disease process. Recently, we predicted putative T cell self-epitopes based on a computer search profile. I...

Plectranthus amboinicus (P. amboinicus) is a folk herb that is used to treat inflammatory diseases or swelling symptoms in Taiwan. We investigated therapeutic efficacy of P. amboinicus in treating Rheumatoid Arthritis (RA) using collagen-induced arthritis animal model. Arthritis was induced in Lewis rats by immunization with bovine type II collagen. Serum anti-collagen IgG, IgM and C-reactive p...

Antigen-specific lymphocytes are involved in synovial proliferation within inflamed joints. Activated lymphocytes and synoviocytes from patients with rheumatoid arthritis express receptors that can bind TNF-related apoptosis-inducing ligand (TRAIL). A new study demonstrates that DCs pulsed with collagen and transduced with an adenovirus-based vector able to express TRAIL limit the incidence of ...

An increase in the antiheparin activity of the plasma occurs in conditions in which there is an increased tendency to thrombosis. Thus an increase in antiheparin activity occurs in the week or two after surgery (Godal and Fichera, 1961; HolgerMadsen and Schi0ler, 1959; Gormsen and Haxholdt, 1960), after myocardial infarction (Beaumont, Chevalier, and Lenegre, 1948; Holger-Madsen, 1960), and aft...

INTRODUCTION Pristane-induced arthritis (PIA) in the rat has been described as an animal model of inflammatory arthritis which exhibits features similar to rheumatoid arthritis in humans, such as a chronic, destructive, and symmetrical involvement of peripheral joints. However, so far little is known about the earliest inflammatory events and their influence on locomotor behaviour during the co...

Introduction: The systemic and local content of inflammatory cytokines and chemokines play substantial roles in pathophysiology of arthritis. This study was purposed to verify the roles of synovial TNF-α, IL-6 and fractalkine (Fkn) in edema changes during different stages of Complete Freund’s Adjuvant (CFA)-induced knee arthritis in rats. Methods: 168 male Wistar rats were divided i...

The effect of adjuvant-induced arthritis on hepatic microsomal glucuronidation was studied in the rat. Arthritis was induced by injection of Mycobacterium butyricum suspended in liquid paraffin. Vmax and the Michaelis-Menten constant values for the in vitro glucuronidation of R- and S-ketoprofen, acetaminophen, and diflunisal by liver microsomes obtained from control and adjuvant-induced arthri...

The anti-arthritic effects of epoxyquinomicins on type II collagen-induced arthritis in DBA/1J mice were examined. Prophylactic treatment with epoxyquinomicins A, B, C and D (1-4 mg/kg) had potent inhibitory effects on type II collagen-induced arthritis. In contrast to nonsteroidal anti-inflammatory drugs (NSAIDs), epoxyquinomicin C (1-30 mg/kg) had neither an anti-inflammatory effect on carrag...
