Ketoacids and the insulin receptor
Diabetes, 1978The binding of insulin to a specific receptor on IM-9-cultured human lymphocytes was studied in vitro under conditions simulating diabetic ketoacidosis. Compared with control incubations at pH 7.4, binding was reduced by 19 per cent at pH 7.1 and by 48 per cent at pH 6.8. Addition of β-hydroxybutyrate, at concentrations similar to those seen clinically,

Effect of insulin receptor autophosphorylation on insulin receptor binding
Molecular and Cellular Endocrinology, 1986Insulin receptor beta-subunit autophosphorylation, the first event occurring after insulin binding, plays a crucial role in modulation of receptor-associated kinase activity towards exogenous substrates and possibly in the transmission of biological signals of insulin. Receptor autophosphorylation strongly depends on insulin receptor occupancy.

The insulin receptor endocytosis
2023Insulin signaling controls multiple aspects of animal physiology. At the cell surface, insulin binds and activates the insulin receptor (IR), a receptor tyrosine kinase. Insulin promotes a large conformational change of IR and stabilizes the active conformation.

Diabetes, 1972
Studies with bulky and insoluble insulin derivatives indicate that this hormone can activate various metabolic processes by interaction with cell surface structures. A definition of “receptor” is offered which is operationally useful in studies directed to the identification and purification of receptor structures.

THE ERYTHROCYTE INSULIN RECEPTOR
Australian Journal of Experimental Biology and Medical Science, 1981SummaryA precise, reproducible radioreceptor assay has been developed for insulin receptors on human erythrocytes. The mean specific binding in 11 normal volunteers was 7.7% ± 1.6 (S.D.) per 2.25 × 109 erythrocytes. The intra and inter assay coefficients of variation are 4%.

The insulin receptor and the kidney
Current Opinion in Nephrology and Hypertension, 2013In recent years, it has become clear that the insulin receptor is important in a variety of renal cell types. It is through this transmembrane receptor that insulin, and to a lesser extent insulin-like growth factor, hormones bind and can control important cellular functions.

Insulin Receptors, Receptor Antibodies, and the Mechanism of Insulin Action
1981Publisher Summary Insulin exerts a wide spectrum of effects at the cellular level. These include effects at the membrane level, for example, the stimulation of glucose and amino acid uptake; effects on both membrane and cytoplasmic enzymes; and effects on protein synthesis, DNA synthesis, cell growth, and differentiation.

Insulin Receptor Antibodies and Insulin Resistance
Southern Medical Journal, 1999The presence of insulin receptor antibodies is a rare cause of insulin resistance. Patients usually have a combination of hyperglycemia, insulin resistance, acanthosis nigricans, and autoimmune features. We report a patient with systemic lupus erythematosus and severe insulin resistance due to insulin receptor antibodies.

Insulin Receptors and Insulin Resistance
Annual Review of Medicine, 1983Resistance to the action of insulin plays a central role in many important disease states, including diabetes and obesity. Many insights into the mechanism and significance of insulin resistance in these and other disorders have followed upon our expanding knowledge regarding insulin receptors.

The Immunology of the Insulin Receptor
Immunological Communications, 1976We have detected and characterized anti-insulin-receptor autoantibodies which circulate in several patients with insulin resistance diabetes. These antibodies are predominantly IgG and are polyclonal. They inhibit insulin binding to its receptor on a variety of tissues from widely separated species. Antibodies obtained from different patients appear to
