Anxiety-like behavior in the light-dark box (LDB). Bar graphs show the results of the LDB in B7-H1 ko and wildtype littermates (WT). Mice were investigated after chronic constriction injury (CCI) and sham surgery. No differences were found after CCI in the number of entries into the dark box (a) and into the light box (b). Also, time spent in the light box (c) and the time mice spent in the dark box (d) did not differ between genotypes and surgeries. B7-H1 ko: sham: 6 males, CCI: 8 males. WT: sham: 6 males, CCI: 7 males
