چکیده انگلیسی
Drugs of abuse cause persistent alterations in synaptic plasticity that is thought to underlie addictive-like behaviors. Although, the perisynaptic glial cells are implicated in metabolic maintenance and support of the nervous systems, accumulating evidence suggests that glial cells exert a modulatory action on synaptic functions and participate in synaptic plasticity. However, it is well-documented that glial cells are associated with the acquisition of rewarding effects of abused drugs. The role of hippocampal glial cells in addictive-like behaviors remains poorly understood. In this study, we investigated the role of hippocampal glial cells in morphine-induced behavioral responses including morphine dependence, tolerance to the antinociceptive properties of morphine, and conditioned place preference (CPP). Male rats received subcutaneous (s.c.) morphine sulfate (10â¯mg/kg) at an interval of 12â¯h for 9â¯days. To suppress glial cells activity, the animals received microinjection of fluorocitrate (FC, a metabolic inhibitor of glial cells) into the CA1 region before each morphine administration. The animals were assessed for morphine dependence by monitoring naloxone hydrochloride-induced precipitation of somatic signs of morphine withdrawal. The tolerance to the antinociceptive effects of morphine and morphine-induced CPP were measured in a separate set of experimental groups. We found animals receiving FC before morphine injection demonstrated a significant reduction in several signs of morphine withdrawal such as freezing, defecation, chewing, explosive running, ptosis, activity, scratching, wet dog shake, and writhing. Inhibition of glial cells caused a significant reduction of tolerance to the antinociceptive effect of morphine. Finally, intra-CA1 administration of FC decreased morphine-induced CPP. Our findings suggest that hippocampal glial cells may be involved in morphine-induced behavioral responses.
