چکیده انگلیسی
Long-term repeated application of morphine induces plasticity changes in sensitive neurons, which represents the neurobiological basis of morphine addiction. Caveolin-1 (Cav-1) is an important scaffolding protein that plays a key role in the regulation of neurostructural plasticity. However, in-depth studies focused on the role of Cav-1 in morphine-induced changes in neurostructural plasticity are lacking. The present study explored the effects of Cav-1 on the expression levels of 2 markers of neurite outgrowth, growth association protein 43 (GAP-43) and microtubule-associated protein 2 (MAP-2), during the process of morphine-induced changes in the structural plasticity. A primary mouse cerebral cortical neuron culture was established, and Cav-1 knockdown was achieved. The results showed that morphine at a concentration of 10.0 μmol/L had no adverse effect on neuronal viability, but enhanced the Cav-1 and GAP-43 levels and induced the outgrowth of MAP-2-labeled neurites. The qRT-PCR data showed that 10.0 μmol/L of morphine increased the Cav-1 mRNA level and promoted Cav-1 expression at the transcriptional level. Moreover, Cav-1 knockdown inhibited the morphine-induced upregulation of GAP-43 expression and the prolongation of MAP-2-labeled neurites. In conclusion, morphine was capable of inducing changes in the structural plasticity of primary cultured mouse cortical neurons, and Cav-1 played an important role in this process. Inhibition of Cav-1 expression reduced the morphine-induced increase in the neuronal growth markers GAP-43 and MAP-2. Thus, Cav-1 may be a potential molecular target for inhibiting morphine-induced neuroplasticity.
