From: Sensing and avoiding sick conspecifics requires Gαi2+ vomeronasal neurons
Neither feces extract of LPS-treated mice nor bile acids induce avoidance behavior. a Conspecific investigation assay in which male mice were exposed to two healthy anesthetized males painted with FE solution of LPS- or PBS-treated males. b Investigation times of cGαi2+/− vs. cGαi2−/− mice (n = 13 and 15, respectively; cGαi2+/−: unpaired t-test: t (24) = −1.29, p = 0.21, cGαi2−/−: unpaired t-test: t (28) = −0.61, p = 0.55). c log2 investigation time ratios (preference score) (unpaired t-test: t (26) = −0.8, p = 0.43). d Male mice were allowed to investigate two healthy anesthetized male conspecifics painted with PBS solution supplemented with 10 μM CA + 10 μM DCA or with PBS alone. e Investigation times of healthy conspecifics painted with PBS or with PBS supplemented with CA/DCA in cGαi2+/− vs. cGαi2−/− mice (n = 13, 11, respectively; cGαi2+/−: Mann-Whitney ns, p = 0.76, cGαi2−/−: Mann-Whitney ns, p = 0.39). f log2 investigation time ratios (preference score) for healthy conspecifics painted with CA/DCA solution (unpaired t-test: t (22) = 0.83, p = 0.41)
