IL-23R, IL-12Rβ2, STAT4 and phospho-STAT4 expression on CD4
T cells from MS patients treated with β-interferon. Western blot analysis of (A) IL-23R and IL-12BR2 (B) pSTAT4 and STAT4 were performed by using total proteins extracted from CD4+T cells from three patients before and after treatment with B-interferon. In each panel a polyacrylamde gel shows the results of one representative experiment. Densiometry reports the relative intensity of all three patients. GAPDH was used as the internal loading control. (Data shown are all from the same patient).
