Electroacupuncture at Governor Vessel improves neurobehavioral function via reduction of complexin1 release_4dlkojv4ffh3flmmjficnhynny

Abstract

Electroacupuncture at Governor Vessel (GV), as a traditional chinese medicine, has been proved that it can reduce scar and promote axon regeneration. However, the underlying mechanism remains unclear. Herein, complexin1 (CPLX1), as a candidate protein, was found using protein chip. Therefore, using a CRISPR/Cas9 knockout approach, we deleted CPLX1 specifically in the SD rats to assess the role of CPLX1 in GV treatment. Additionally, eIF5A1 stimulate the translation of CPLX1 with PPG sequence, we attempt to uncover whether eIF5A1 play a role in the GV treatment. In fact, GV can reduce scar and promote axon regeneration after SCC. CPLX1-/+ SCC rats demonstrated that decreased CPLX1 improved the microenvironment of injured area via reducing the components of fibrotic scar and further enhanced the synaptic plasticity, which benefit the regeneration of axons. And eIF5A1 could regulate the expression of CPLX1 in the process of GV treatment. Therefore, GV contributes to axon regeneration and synapse plasticity via eIF5A1 regulating CPLX1 following SCC, providing a convincible mechanism for improving the therapeutic efficacy of GV for SCC.
