Article Title: Expression of Vesicular Glutamate Transporters VGLUT1 and VGLUT2 in the Rat Dental Pulp and Trigeminal Ganglion following Inflammation
doi: 10.1371/journal.pone.0109723
Figure Lengend Snippet: A: Immunofluorescent staining for VGLUT1 (a, b) and VGLUT2 (c, d) in the rat trigeminal ganglion in the control (a, c) and CFA 1-day (b, d) groups. VGLUT1 is expressed predominantly in medium- and large-sized somata (a, b), whereas VGLUT2 is expressed predominantly in small- and medium-sized somata (c, d). The number of VGLUT1+ somata of all somata is not different between control (a) and CFA 1-day group (b), whereas that of VGLUT2+ soma is significantly higher in the CFA 1-day (d) than in the control (c) groups. Scale bar = 50 µm. B: The density of VGLUT2+ somata (fraction of all somata) is significantly higher for the CFA 1-day, CFA 3-day groups than control, whereas the density of VGLUT1+ soma is not significantly different between CFA 1-day or CFA 3-day groups and control. N = 3 animals in each group. *p<0.01. C: Representative images of the Western blot assay for VGLUT1 and VGLUT2 in the rat trigeminal ganglion. D: Quantitative analysis of VGLUT1 and VGLUT2 protein in the trigeminal ganglion. The VGLUT2 protein levels are significantly higher in the CFA 1-day and CFA 3-day groups than for the control, whereas the VGLUT1 protein levels are not different between CFA 1-day or CFA 3-day groups and the control group. N = 5 animals in each group. *p<0.01.
Article Snippet: Preadsorption controls with blocking peptides for VGLUT1 (15 μg/ml; #135-3P, Synaptic Systems) and VGLUT2 (10 μg/ml; #G07B-VGLUT2-AG, Frontier Science) also completely abolished the respective staining.
