Effects of T cells and CFA on measures of sickness behavior. A) Spontaneous locomotor activity was assessed 3, 9 and 20 days after intraplantar CFA or saline -injection in WT, Rag2^−/−, and reconstituted Rag2^−/− mice (n = 4–5 mice/group). B) Body weight was monitored over time in WT, Rag2^−/−, and reconstituted Rag2^−/− mice after CFA or saline injection (n = 4–5 mice/group).
