Figure.3. HFD-fed IDO KO mice have impaired memory.

IDO KO and wild type (WT) mice were fed a LFD or HFD for 1 wk. Exploration of a familiar and novel object were measured for 5 min. Results are expressed as % investigation of the novel object compared to the familiar object, means ± SEM; n = 12. Bars without a common superscript are different (P < 0.05).
