Neurochemical features of enkephalinergic neurons in the mouse trigeminal subnucleus caudalis

▶ PPE-GFP transgenic mice were used to aid in the identification of ENKergic neurons. ▶ Part of ENKergic neurons in the Vc coexpressed GABA, CB, CR or PV. ▶ A small number of ENKergic neurons in the Vc were projecting neurons.
