    SO-Aβ induces changes in the mRNA expression levels of P2X subunits. A) Quantification of relative mRNA for P2X subunits at 12 h of treatment with Aβ (0.5 μM) revealed that the subunits P2X1, 2, 5 and 7 had a significant increase in their expression (P2X1: 1.25 ± 0.007, P = 0.0009; P2X2: 1.23 ± 0.06, P = 0.029; P2X5: 1.21 ± 0.06, P = 0.039; P2X7: 1.42 ± 0.06, P = 0.019; P2X3: 0.95 ± 0.09, P = 0.636; P2X4: 1.21 ± 0.07, P = 0.056; P2X6: 1.03 ± 0.22, P = 0.918). B) Quantification of the relative expression of P2X at 24 h of treatment (Aβ, 0.5 μM) showing that at this time point only P2X2 remained significantly increased (P2X2: 1.2 ± 0.04, P = 0.022; P2X1: 1.1 ± 0.06, P = 0.152; P2X3: 0.9 ± 0.08, P = 0.286; P2X4: 1.16 ± 0.07, P = 0.110; P2X5: 1.13 ± 0.05, P = 0.096; P2X6: 0.95 ± 0.15, P = 0.783; P2X7: 1.21 ± 0.13, P = 0.193), n = 5. *P

A , Immunofluorescence detection (red represents anti-HA; green represents anti-eGFP) was performed 48 h after transfection. Arrows indicate the axons. Scale bar, 50 μm. B , Cumulated fluorescence intensity profiles of 5-HT 3A R-HA along the axons (longest path, n = 30) for 5-HT 3A R-HA plus eGFP (blue) or 5-HT 3A R-HA plus P2X2-YFP (red). C , Cumulated fluorescence intensity profiles of eGFP and P2X2-YFP along the same axons ( n = 30) for 5-HT 3A R-HA plus eGFP (green) or 5-HT 3A R-HA plus P2X2-YFP (orange). D , Quantification of the number of neurons exhibiting 5-HT 3A R-HA immunofluorescence at distances above (distal) or below (proximal) 100 μm from somas for 5-HT 3A R-HA plus eGFP or 5-HT 3A R-HA plus P2X2-YFP. Bars represent the relative proportions of the two groups (mean ± SEM) for each cotransfection condition (two-way ANOVA, n = 324 and n = 399, respectively, p

    Article Snippet: We have used previously described antibodies against the 5-HT3A ( ) and the 5-HT3B ( ) subunits to illustrate such a coexpression of native 5-HT3 and P2X2 receptors in neurons of the rat myenteric plexus using two independent couples of antibodies: rabbit anti-5-HT3A and guinea pig anti-P2X2 (Millipore) ( A ) and goat anti-5-HT3B and rabbit anti-P2X2 (Alomone Labs) ( B ).
