Response of insulin receptors to oral glucose in normal subjects
- 3 Downloads
Insulin binding to circulating monocytes was studied in ten male volunteers before and 1, 2, and 5 hours after the oral intake of 100 g of glucose. Results indicate an increase in the specific cell binding fraction with a change in receptor affinity 5 hours after glucose. Since the same changes appear 3 hours after food intake they are probably not directly induced by insulinemia.
