ABSTRACT
Aim To investigate the role of collybistin in the regulation of pain transmission. Methods The distribution of collybistin in spinal cord was observed by immunohistochemical staining. The role of collybis¬tin in pain transmission was evaluated by behavioral experiments. The effect of collybistin on inhibitory synap¬tic transmission was studied by electrophysiological ex¬periments. Results Collybistin was distributed in spi¬nal cord neurons; ShRNA-collybistin induced pain sen-sitization of intact mice ( P < 0. 05 ) . Overexpression of collybistin in spinal cord significantly alleviated pain sensitization induced by peripheral nerve injury ( P <0. 05 ) . ShRNA-collybistin also significantly reduced the amplitudes and frequencies of miniature inhibitory postsynaptic currents (mlPSCs) in superficial neurons of spinal cord dorsal horn (P <0. 05) . Overexpression of collybistin in spinal cord could reverse the effects of peripheral nerve injury on mlPSCs (P <0. 05). Con¬clusions Collybistin is involved in pain sensitization induced by peripheral nerve injury in mice.
