Fig. 3. IL-6 levels were amplified and protracted in the plasma of aged mice in response to central LPS injection.
Adult and aged mice were injected i.c.v. with either saline or LPS and IL-6 was measured in plasma collected (A) 2 and (B) 8 h later. Bars represent the mean ± SEM (n=7). Means with * are significantly different (P < 0.05) from saline controls and means with ‡ are significantly different from Adult LPS.
