Gene expression analysis of the hippocampus in Il18+/+ and Il18-/- with restraint stress

Interleukin-18 (IL-18) was one of the inflammatory cytokines and related to major depressive disorder (MDD) and dementia. We previously investigated IL-18 knockout (Il18-/-) mice developed impaired learning and memory, more anxiety, and less motivation comparing to Il18+/+ mice. In the Il18-/- mice with acute stress, both the immobility time in the forced swim test and the tail suspension test were decreased, even though no difference was observed in the Il18+/+ mice. To reveal the mechanism, RNA-Seq was performed. Overall design: RNA-seq
