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.

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.

Pathologie Biologie, 2003
The number of elderly people is increasing worldwide as well as the age-associated diseases, such as the type 2 diabetes. The consequences are disastrous for elderly patients as well as for healthy ageing. It has been clinically demonstrated that with physiological ageing it exists already a resistance to the action of insulin leading to slightly ...

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.

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.

Autoantibodies to insulin receptors
Molecular and Cellular Endocrinology, 1981In summary, these studies using antibodies to the insulin receptor have provided some new insights into the structure of the insulin receptor and the action of insulin itself. They suggest that most of insulin's actions are mediated through a common pathway and these can be initiated by interaction of ligands other than insulin with the insulin ...

Biochimie, 1985
The insulin receptor appears as a tetrameric glycoprotein consisting of two Mr 130,000 subunits (alpha), and two Mr 95,000 subunits (beta) in a disulfide-linked complex. Insulin bound to its specific cell surface receptors in its target cells leads to a complex array of molecular events resulting in insulin effects.
