Metabolic responses to intraduodenal glucose loading in insulin-infused diabetic dogs. In the 10 years leading up to T2D onset, your post-meal glucose gradually rises, and more and more insulin is secreted in response, but you develop insulin resistance. Around year 0 where onset is defined , beta cells start to fail, and insulin secretion goes back down, declining gradually over 30 years. HbA1c is glycosylated hemoglobin — hemoglobin is ordinarily unglycosylated but becomes glycosylated if there is too much glucose in the blood.

HbA1c is another risk marker. After insulin resistance, impaired insulin secretion and beta cell failure follow next. There are likewise a few hypotheses about these:. Eric Vallabh Minikel is on a lifelong quest to prevent prion disease. Follow cureffi. A quick comparison of the two types: Type 1 is an autoimmune disorder that kills pancreatic beta cells, resulting in insulin deficiency — it can be treated with insulin. It results in the presence of antibodies against beta cells, though the ultimate cause is not known.

Type 2 The rise in T2D prevalence can be attributed to a couple factors: 1 overnutrition, obesity, inactivity; 2 treatment of T2D has improved, and therefore people live longer with it. Adipose tissue dysfunction — the role of inflammation. When adipocytes get too large in overweight people , the overloading of TAG causes release of MCP-1, a chemoattractant.

TAG storage becomes impaired, resulting in lipolysis and increasing the circulating TAGs and free fatty acids, allowing them to accumulate ectopically in muscle. Insulin resistance in liver and muscle — the role of mitochondria. In either case 1 or 2 above, fatty acids accumulate in the liver. Overnutrition also increases malonyl-CoA in the liver, and malonyl-CoA inhibits CPT1 carnitine palomitoyltransferase 1 which inhibits fatty acid oxidation.

In lieu of oxidation, TAG storage increases. Fatty acid metabolism during CPT1 inhibition also produces diacylglycerol and ceramide. DAG activates stress-induced kinases, and both these and ceramide reduce insulin signaling. Meanwhile in the muscle, fatty acid accumulation increases beta oxidation thereof, and reduces citric acid cycle activity.

Products of incomplete fat oxidation acylcarnitines and reactive oxygen species activate stress-induced kinases, which reduce insulin signaling. There are likewise a few hypotheses about these: Role of mitochondria and pyruvate cycling.
