Abstract: | Type II collagen (CII) is a cartilage structural protein that plays important roles in joint function, arthritis and ageing. In studying the ability of CII to induce eye‐mediated specific immune tolerance, we have recently proven that CII is capable of inducing anterior chamber‐associated immune deviation (ACAID) in Balb/c mice. Here, we study the ability of CII to induce eye‐mediated immune tolerance in strains of mice that are prone to the induction of rheumatoid arthritis. Thus, we hypothesized that CII induces ACAID in DBA/1 mice and in C57BL/6 mice through the AC route (direct injection) or the intravenous route (adoptive transfer of in vitro‐generated CII‐specific ACAID macrophages or of CII‐specific in vitro‐generated T regulatory cells). Specific immune tolerance induction was assessed using both delayed‐type hypersensitivity (DTH) and local adoptive transfer (LAT) assays. Results indicated the ability of CII to generate CII‐specific ACAID‐mediated immune tolerance in vivo and in vitro in both DBA/1 mice and C57BL/6 mice. These findings could be beneficial in studies of immune tolerance induction using CII. |
