Figure 4. Effect of deletion of B2m, Ctss, Il1rn, Cd14 or Il6 on preference for ethanol in one bottle DID procedure (1B-DID) in male mice.

Figure 4

A. B2m knockout mice. B. Ctss knockout mice, (p<0.001, effect of genotype for the period with 2 hrs access). C. Il1rn knockout mice, (p<0.001, effect of genotype for the period with 2hrs access). D. Cd14 knockout mice. E. Il6 knockout mice. ** - p<0.01, *** - p<0.001 – statistically significant differences between mutant and correspondent wild type mice for the period with 4 hrs access (Student’s t-test). n = 7 – 9 for all groups. Ethanol was used in concentration 20%.
