Methamphetamine is a potent and highly addictive neurotoxic psychostimulant that triggers a spectrum of adverse emotional responses during withdrawal.G-protein coupled receptor 55 (GPR55), a novel endocannabinoid receptor, is closely associated Concealment Gloves with mood regulation.Herein, we developed a murine model of methamphetamine-induced anxiety- and depressive-like behavior during abstinence which showed a decreased GPR55 expression in the hippocampus.Activation of GPR55 mitigated these behavioral symptoms, concomitantly ameliorating impairments in hippocampal GINKGO MEMORY CAPS neurogenesis and reducing neuroinflammation.These findings underscore the pivotal role of GPR55 in mediating the neuropsychological consequences of methamphetamine withdrawal, potentially via mechanisms involving the modulation of hippocampal neurogenesis and inflammation.
