Fig. 3. IL-6 levels were amplified and protracted in the plasma of aged mice in response to central LPS injection.

Fig. 3

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.
