VGLUTs in Peripheral Neurons and the Spinal Cord: Time for a Review

Table 1

Percentage of DRG neurons (visceral or nonvisceral) expressing VGLUTs (protein and mRNA).

VGLUT	Species	Percent nonvisceral afferents	Percent visceral afferents (target organs)
VGLUT1 protein	Mouse	~37% [53]; ~12% [54]	~12% (Colorectum [61]); ~32% (U. Bladder [62])
	Rat	Detected, not quantified [48]	NE (Colorectum, U. Bladder)
VGLUT1 mRNA	Mouse	~40% [136]	NE (Colorectum, U. Bladder)
	Rat	Detected, not quantified [48]	NE (Colorectum, U. Bladder)
VGLUT2 protein	Mouse	~65% [54]	~97% (Colorectum [61]); ~94% (U. Bladder [62])
	Rat	NE	Detected, not quantified (Stomach and Ileum [44]); NE (Colorectum, U. Bladder)
VGLUT2 mRNA	Mouse	~70% [136]	NE (Colorectum, U. Bladder)
	Rat	NE	NE (Colorectum, U. bladder)
VGLUT3 Protein	Mouse	~10% [66]; ~19% [65]	~10% (Colorectum*); ~18% (U. Bladder [62])
	Rat	NE	NE (Colorectum, U. bladder)
VGLUT3 mRNA	Mouse	~17% [136]; ~16% [65]	NE (Colorectum, U. Bladder)
	Rat	NE	NE (Colorectum, U. Bladder)

NE: not evaluated; *unpublished data; tissue has been processed and NPs quantified according to references [54, 60–62].
