Induction of hypothermia by MWReg30 but not other MoAbs—requirement of platelets. Normal (A) or thrombocytopenic (B) male NMRI mice received 100 μg of affinity-purified MWReg30 IP in 100 μL sterile PBS. As control for platelet-specific antibodies, normal mice received 100 μg affinity-purified MWReg31 (C) or 100 μL of a rabbit antimouse platelet serum (D). The mean values of the body temperatures of 3 mice per group at the indicated times after injection of the antibodies are given ± SD.
