Western blot analysis for active forms of inflammatory factors in rat brains at four weeks after stroke. TNF-α: levels of TNF-α were decreased in ischemic rat brains and treatment with minocycline facilitated the reduction. IL-1β: *P <0.05 versus V-I. IL-10: *P <0.05 versus V-I. TGF-α: *P <0.05 versus V-I; ##
P <0.01 versus V-C and Mino-C. n = 8 in the vehicle group, 9 in the minocycline group.
