title: Arginine does not influence insulin binding on circulating monocytes.
abstract: Glucose ingestion, food intake or acute exercise produced rapid variations in insulin binding on monocytes. Insulin seems to play a minor or any role in this phenomenon in contrast pancreatic glucagon might be involved since it usually rises when an increase in insulin receptor affinity has been observed. To investigate the role of pancreatic glucagon we have studied the effect of arginine infusion on monocyte insulin receptor in five normal subjects. Results indicate that the aminoacid employed does not induce any change in insulin receptor affinity and concentration suggesting that the simultaneous increase in plasma insulin and pancreatic glucagon levels does not exert any action.
