ABSTRACT
In this study, we observed changes in CD4(+) CD25(+) Foxp3(+) Treg expression in rats with osteoarthritis (OA) to explore the role that CD4(+) CD25(+) Foxp3(+) Treg plays in the decline in the condition of OA rats. Thirty rats were randomly divided into 2 groups equally and OA was induced in rats in the model group by injection of papain and l-cysteine into the right knee joint. Cartilage lesions were scored by the modified Mankin scale; pulmonary function was assessed by spirometry; interleukin (IL)-17 and IL-4 levels were evaluated by the enzyme-linked immunosorbent assay; and the levels of CD4(+) CD25(+) Foxp3(+) Treg in peripheral blood were measured by flow cytometry. The left knee joints of the model rats appeared palpable swelling and osteophytes, while the body weight, heart and lung function of these rats decreased. The serum IL-4 level was lower, whereas the serum IL-17 level was higher in the model group (P < 0.05). The peripheral blood CD4(+) CD25(+) Foxp3(+) Treg of CD4(+)T cells was significantly lower. Correlation of the changes in the levels of IL-4, IL-17, and Treg suggests that the underlying mechanism may be a reduction of the regulatory effect of Treg. The specific mechanism still requires further study.
