Different Sickness Responses in Adult and Aged Rats Following Lipopolysaccharide Administration

摘要

Objective: Immune challenges result in sickness responses such as decreased activity, fever, and spatial learning deficits. While these responses occur simultaneously, they are not usually evaluated concurrently or for an extended time. The purpose of this study was to examine how an immune challenge affected activity and temperature responses in animals tested concurrently in the Morris water maze (MWM) over 5 days and how aging interacts with such responses.
