LPS induced-hypothalamic immune response was altered by hypocretin loss.
Hypocretin expression was completely abolished by LPS in hypocretin/ataxin-3 mice.
An increase in HDC cells and Hdc was found in hypocretin/ataxin-3 mice.
Hypocretin loss did impact the change in Ifng and Csf3.
c-Fos-positive/HDC cells in hypocretin/ataxin-3 mice was elevated by LPS.
