Co-localization of synaptophysin and synaptoporin with IB4-binding C fibers in the thoracic dorsal horn. IB4 binding C fibers distributed in lamina II of T7 and T13 dorsal horns and expressed synaptophysin and/or synaptoporin as shown in a representative montage of confocal images from T7. (A) Areas of IB4 binding projections within the investigated region of interest were analyzed at both thoracic levels.(B) Colocalization of IB4 binding axon terminals with synaptophysin or with synaptoporin was assessed by double labeling quantification (C) to find significantly different expression levels of synaptoporin and synaptophysin in this C fiber subpopulation (n = 4, p < 0.05, Kruskal-Wallis test with multiple comparison test, Cohen’s d > 1.3).
