6 The Ticking Clock Hypothesis Type 2 DM is associated with microvascular and macrovascular complications. Duration of DM and severity of glycemia are primarily associated with microvascular disease. Metabolic disturbances during the prediabetic period may contribute to macrovascular disease. Macrovascular complications: the clock starts ticking years before the onset of clinical diabetes.

66 PCSK9 (Proprotein convertase subtilisin/kexin type 9) A secreted protein which targets the LDL receptor for degradation Gain of function mutations cause high LDL-C Loss of function mutations cause low LDL-C Inhibition lowers LDL-C levels Up-regulated by statin therapy 82

67 How is cholesterol removed from blood? LIVER Circulating LDL particles (which contain a large ApoB protein) are grabbed by an LDL receptor 83

68 How is cholesterol removed from blood? LIVER The entire complex is then internalized into the hepatocyte for LDL destruction 84

69 How is cholesterol removed from blood? Then the LDL particle is destroyed LIVER Before the LDL particle is destroyed, the LDL receptor migrates back to the hepatocyte cell surface so that it can grab more LDL molecules 85

70 How is cholesterol removed from blood? When PCSK9 is present, however, the LDL-C receptor gets stuck and cannot migrate back to the surface LIVER It therefore gets destroyed along with the LDL And the number of LDL-C receptors on the cell surface is depleted 86

71 The theory behind PCSK9 inhibitors LIVER X If PCSK9 is inhibited, the LDL-C receptor can migrate back to the cell surface And surface LDL receptors will be restored which will reduce the serum LDL-C level 87
