Description
Objective To observe the effects of Cannabinoid type 2 receptor (CB2R) on Aβ-induced hippocampal neuron. Methods Hippocampal neurons were pre-treated with 10 μM JWH133 and then treated 100 nM Aβ42 oligomer for 7 day, the mRNA of Bcl-2 and Bax was measured by qRT-PCR, and the mitochondrial membrane potential and the production of ROS were measured by Flow Cytometry. Result Aβ42 oligomer significantly decreased the ratio of Bcl-2/Bax, and mitochondrial membrane potential, and increased the production of ROS. However, the pre-treatment JWH133 inhibited Aβ42-induced the ratio of Bcl-2/Bax decrease, and increased the mitochondrial membrane potential, decreased the production of ROS. Conclusion Activation of CB2R could inhibit the effects of Aβ42 on hippocampal neurons.
