T cells can still be activated during treatment with Alefacept. Percent CD69 positive cells following in vitro activation with control, anti-CD3 (OKT3) or anti-CD2 (T11.1 and T11.2). Comparison of CD69 expression on T cells activated with either OKT3 or T11.1 and T11.2 at baseline and week 13. No significant differences. Geometric mean data, standard error of the mean.
