Figure 3. Effect of deletion of B2m, Ctss, Il1rn, Cd14 or Il6 on preference for ethanol in two-bottle DID procedure (2B-DID).

Figure 3

Males: A. B2m and Ctss knockout mice. B. Il1rn knockout mice. (p<0.001, effect of genotype). C. Cd14 and Il6 knockout mice. Females: D. B2m and Ctss knockout mice. (p<0.05, effect of genotype for the Ctss knockout mice) E. Il1rn knockout mice. (p<0.001, effect of genotype) F. Cd14 and Il6 knockout mice. (p<0.01, effect of genotype for the Cd14 knockout mice) n = 10 – 14 for all groups. Ethanol was used in concentration 20%.
