Abstract
Interleukin (IL)-18, a member of the IL-1 cytokine family, is an important mediator of peripheral inflammation and host defence responses. However, although IL-1 is a key proinflammatory cytokine in the brain, little is known about IL-18 changes in glial cells under excitotoxic neurodegeneration. In this study, we characterized the expressions of IL-18 and IL-18 receptor (IL-18R) in kainic acid (KA)-induced excitotoxicity in mouse hippocampus by immunohistochemistry and Western blotting. IL-18 immunoreactivity was found in microglia whereas IL-18R immunoreactivity was observed in astrocytes. Levels of IL-18 and IL-18R in hippocampus homogenates increased progressively from day 1 post-KA and peaked at 3 days. This study demonstrates the cellular sources of IL-18 and IL-18R, and their temporal correlations after KA-insult, and suggests roles for IL-18 and IL-18R in glial cells in response to excitotoxic damage in the hippocampus.Entities:
