Effects of LPS treatment and sweetened milk consumption on the proportion of orexin neurons displaying c-Fos ir in lateral (LH, A), perifornical (PF, B) and medial (MH, C) parts of their range of distribution (see diagram of section through the hypothalamus between A’ and B’, modified from Paxinos and Watson, 1998). The sweetened milk-related increase in c-Fos expression, significant in the LH (A) and MH (C) portions of orexin neurons in saline-treated groups, is reduced following LPS challenge, most notably in the lateral-most portion of orexin-containing neurons (LH, in A). In the MH portion of the orexin neurons, however, c-Fos expression is increased following LPS challenge alone (C). There were no differences in the total number of orexin neurons between the groups (right panels A’–C’). * p < 0.05, LPS vs. saline treatment. # p < 0.05, sweetened milk vs. water exposure.
