Figure 1 Autoantibodies against GPIHBP1 Provoke Hyperchylomicronemia
Left panel: metabolism of triglyceride-rich lipoproteins under normal circumstances. LPL is produced by adipocytes and myocytes and transported from the surface of these cells to the capillary lumen by GPIHBP1. Right panel: autoantibodies against GPIHBP1 prevent the transport of LPL to the capillary lumen. The resultant functional LPL deficiency leads to impaired clearance of triglyceride-rich lipoproteins, causing hyperchylomicronemia. LPL, lipoprotein lipase; GPIHBP1, glycosylphosphatidylinositol-anchored HDL binding protein 1; HSPG, heparan sulfate proteoglycan; TG, triglycerides.
