Introduction:
Stroke is a prevalent disorder which is associated with several complications including inflammation. JZL-184 (JZL) inhibits arachidonic acid (AA) production and consequently results in two-arachidonoylglycerol (2-AG) accumulation. Both reduced production of AA metabolic products and increased 2-AG, the agonist of type 1 cannabinoid receptor (CB1), can result in reduced inflammation. In this study, we investigated the mechanisms of JZL in the improvement of stroke complications in mouse permanent cerebral ischemia (PPMCAO) model using AM251, the antagonist of CB1.
Material And Methods:
PMCAO mice were divided into six groups including intact, controls, vehicle, JZL, AM251 and JZL plus AM251 administrated groups. Brain infarction and edema, brain levels of matrix metalloperoteinase-9 (MMP9), interleukin (IL)-10 and tumor necrosis factor-α (TNF-α) and behavioral functions have been examined in all groups.
Results:
The results showed that JZL lowered brain infarction, neurological disorders, TNF-α and MMP9 more effectively than JZL plus AM251. JZL and JZL plus AM251 reduced brain edema and increased brain IL-10. JZL, AM251 and JZL plus AM251 improve behavioral functions.
Discussion:
JZL reduces brain infarction and brain pro-inflammatory molecules in CB1 pathway dependent manner. JZL also reduces brain edema and increased IL-10 in CB1 pathways or decreased AA metabolites. Further, AM251 improves behavioral functions via unknown mechanisms.
