Neuroligin 2 regulates spinal GABAergic plasticity in hyperalgesic priming, a model of the transition from acute to chronic pain.

abstract：:Despite many studies, the mechanisms underlying the pathogenesis of pain in cluster headache (CH) still remain obscure. An involvement of substance P (SP) containing neurons of the Gasserian ganglion and/or of the spinal trigeminal nucleus has recently been suggested, e.g., by impairment of inhibitory descending pathw...
