Pinealectomy ameliorates collagen II-induced arthritis in mice

Type Ii Collagen - Induced Arthritis in Mice

The induction of immunological reactivity to type II collagen, a major component of cartilage, has recently been used to establish an experimental model of arthritis in the rat (1). Trentham and colleagues (1) have shown that the intradermal injection of collagen in Freund's complete or incomplete adjuvant elicits an arthritogenic reaction, specifically with native type II collagen. Arthritis o...

Eupatilin Ameliorates Collagen Induced Arthritis

Eupatilin is the main active component of DA-9601, an extract from Artemisia. Recently, eupatilin was reported to have anti-inflammatory properties. We investigated the anti-arthritic effect of eupatilin in a murine arthritis model and human rheumatoid synoviocytes. DA-9601 was injected into collagen-induced arthritis (CIA) mice. Arthritis score was regularly evaluated. Mouse monocytes were dif...

Bacterial lipopolysaccharide potentiates type II collagen-induced arthritis in mice

Collagen-induced arthritis (CIA) is an immunologically relevant animal model of human rheumatoid arthritis. Studies comparing the disease incidence in genetically susceptible male and female DBA/1LacJ mice demonstrated that under low density/low stress housing conditions, female mice had earlier onset (day 35) and higher disease incidence (25%) than the male mice (17% at day 49) when immunized ...

Inhibition of Collagen-Induced Arthritis in Mice

Restricted expression of anti-type II collagen antibody isotypes in mice suppressed for collagen-induced arthritis.

The present study details the time course and isotype distribution of the immune response to type II collagen in collagen-induced arthritic mice and mice suppressed for collagen-induced arthritis. The serum of arthritic mice was observed to contain significantly higher (p less than 0.005) concentrations of antibodies to type II collagen than that of mice suppressed for arthritis at all times te...
