Figure 2From: Methotrexate enhances the anti-inflammatory effect of CF101 via up-regulation of the A3adenosine receptor expressionImmunohistochemistry analysis of A3AR expression in paws from AIA rats. We conducted immunohistochemistry staining of paraffin-embedded sections of paw from MTX-treated, CF101-treated and MTX+CF101-treated AIA rats. MTX treatment induced receptor expression, and treatment with CF101 alone or in combination with MTX resulted in receptor downregulation. A3AR, A3 adenosine receptor; AIA, adjuvant-induced arthritis; MTX, methotrexate.Back to article page
