1 Metformin ameliorates extreme insulin resistance in a patient with anti-insulin receptor antibodies: description of insulin receptor and postreceptor effects in vivo and in vitro. Metformin insulin Homo sapiens
2 The effect of metformin on insulin binding and insulin action in the presence of anti-insulin receptor antibodies was investigated in a case of type B extreme insulin resistance. Metformin insulin Homo sapiens
3 Oral administration of metformin (1500 mg/d) for 10 days significantly decreased plasma blood glucose and insulin levels and enhanced the hypoglycemic response to exogenous insulin. Metformin insulin Homo sapiens
4 Oral administration of metformin (1500 mg/d) for 10 days significantly decreased plasma blood glucose and insulin levels and enhanced the hypoglycemic response to exogenous insulin. Metformin insulin Homo sapiens
5 It is suggested that metformin increases, possibly through a change in the spatial conformation of insulin receptor within the plasma membrane, the availability of pre-existing receptors to insulin binding and/or decreases the availability of specific epitopes to antibody anchoring. Metformin insulin Homo sapiens
6 Further, in the model of insulin resistance described here, metformin enhanced the basal rate of glucose transport through a direct insulin-mimicking activity and/or a potentiation of the sensitivity of glucose transport to the antibody. Metformin insulin Homo sapiens
7 Further, in the model of insulin resistance described here, metformin enhanced the basal rate of glucose transport through a direct insulin-mimicking activity and/or a potentiation of the sensitivity of glucose transport to the antibody. Metformin insulin Homo sapiens
