The connexin-43 ultrastructural immunohistochemistry of a convoluted proximal tubule. Connexin-43 (Cx-43) immunostaining was observed in the space between the interdigitations (arrow) and in the cytoplasmic compartments of the endothelial cells (arrowheads) in the convoluted proximal tubules of the SED-WKY (a) and EX-WKY (b) control groups. The SED-SHR (c) and EX-SHR (d) groups showed decreased Cx-43 expression. Abbreviations: EX, exercised; SHR, spontaneously hypertensive rats; SED, sedentary; WKY, Wistar-Kyoto rats.
