Intranasal administration of insulin to the brain impacts cognitive function and peripheral metabolism

Ott, V., Benedict, C., Schultes, B., Born, J., Hallschmid, M.·2012·Diabetes, Obesity and Metabolism

Abstract

In recent years, the central nervous system (CNS) has emerged as a principle site of insulin action. This notion is supported by studies in animals relying on intracerebroventricular insulin infusion and by experiments in humans that make use of the intranasal pathway of insulin administration to the brain. Employing neurobehavioural and metabolic measurements as well as functional imaging techniques, these studies have provided insight into a broad range of central and peripheral effects of brain insulin. The present review focusses on CNS effects of insulin administered via the intranasal route on cognition, in particular memory function, and whole‐body energy homeostasis including glucose metabolism. Furthermore, evidence is reviewed that suggests a pathophysiological role of impaired brain insulin signaling in obesity and type 2 diabetes, which are hallmarked by peripheral and possibly central nervous insulin resistance, as well as in conditions such as Alzheimer's disease where CNS insulin resistance might contribute to cognitive dysfunction.

  • Intranasal administration of peptides bypasses the blood-brain barrier and results in significant cerebrospinal fluid elevations in substance levels within 40 min without systemic infusion.

    “The direct manipulation of neuropeptidergic central nervous signaling pathways can be achieved via the intranasal administration of peptides, which is known to bypass the blood–brain barrier and result in significant cerebrospinal fluid elevations in substance levels within 40 min, without the need for systemic infusion (14,15).”

  • Impaired CNS insulin signalling might contribute to the association between metabolic disorders such as obesity and diabetes and cognitive impairments, as well as dysthymia.

    “Considering that impaired glucose tolerance as a result of diet-induced obesity abrogates the memory-improving and anxiolytic impact of insulin in mice, 152 impaired CNS insulin signalling might contribute to the association between metabolic disorders such as obesity and diabetes and cognitive impairments, as well dysthymia.156”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
