Effect of TNBS-induced colitis on the expression of TRPV1 receptors in pelvic afferent nerve cell bodies innervating the rat colon (DRG L6-S1)

	TRPV1+ neurons	TRPV1+/NF− neurons	TRPV1+/NF+ neurons
Control	36.1 ± 2.6	22.6 ± 2.8	13.5 ± 2.3
TNBS	46.6 ± 2.4*	34.4 ± 3.2*	12.3 ± 1.7

Results are expressed as percentage of Fast Blue positive nerve cell bodies and are presented as means ±s.e.m.

^*P < 0.05,

^*P < 0.01, significantly different from controls, Student's unpaired t test or two-way ANOVA with post hoc Student–Newman–Keuls test. NF, neurofilament.
