Expression of the P2X2 receptor in different classes of ileum myenteric neurons in the female obese ob/ob mouse

Table 3 Results of the quantitative analysis of double labeling studies of immunoreactivity against the P2X₂ receptor, neuronal nitric oxide synthase, choline acetyltransferase, and calretinin in the myenteric plexus of the ileum from control and ob/ob female mice (n = 4, mean ± SE) (%)

	Control group	Obese group
nNOS-IR+/P2X2-IR+	99.5 ± 0.6	99 ± 1.0
ChAT-IR+/P2X2-IR+	100	100
CalR-IR+/ P2X2-IR+	100	100
P2X2-IR+/nNOS-IR+	19.5 ± 3.6	19.5 ± 3.6
P2X2-IR+/ChAT-IR+	23.6 ± 4.2	24.6 ± 4.37
P2X2-IR+/CalR-IR+	23.7 ± 3.75	21.6 ± 1.20

nNOS: Neuronal nitric oxide synthase; ChAT: Choline acetyltransferase; CalR: Calretinin; IR: Immunoreactivity.
