S1pr2 null mice exhibit less vascular inflammation in the kidney during endotoxemia. Expression of adhesion molecules and procoagulant and proinflammatory markers in kidneys from control WT, LPS-treated WT (WT + LPS), and LPS-treated S1pr2−/− (KO + LPS) mice 18 hours after administration of vehicle or LPS. Immunostaining for (A) E-selectin, (B) VCAM-1, (C) ICAM-1, (D) TF, and (E) MCP-1. Scale bar, 50 μm. Representative fields from 3 to 5 mice are shown. Images were captured with the Axio Imager A1 microscope, using AxioCam MRc camera and the AxioVision 4.8 program (Carl Zeiss Inc.) (original magnification ×40). a, arteriolar endothelium; e, epithelial cell; g, glomerulus; le, leukocyte; ptc, peritubular capillary; v, venule; vs, vascular smooth muscle cell.
