Effect of centrally administered isoproterenol on brain IL-1 production. Rats were injected i.c.m. with either saline or isoproterenol (β-agonist) and sacrificed 30, 60, or 120 min later (n=7/group). Values from saline-injected animals were averaged and presented as 0 min. Additional rats were injected i.c.m. with propranolol (β-antagonist) immediately prior to isoproterenol administration and sacrificed 60 min later (60+P); n=4/group). Brains were dissected and IL-1 measured using ELISA. Bars represent group averages +/− SEM. * represents p < 0.05 compared to saline-injected controls. # represents p < 0.05 compared to isoproterenol-injected animals sacrificed at 60 min.
