Ghrelin receptor in agouti‐related peptide neurones regulates metabolic adaptation to calorie restriction

Ghrelin is the metabolic link connecting calorie restriction to neuroprotection

PERSPECTIVE Ghrelin is the metabolic link connecting calorie restriction to neuroprotection Parkinson's disease (PD) is the second most common neu-rodegenerative disease whereby the number of diagnosed patients rises by 3–4% each year creating an ever-expanding social, medical and financial burden. Symptoms such as rigidity, postural instability and bradykinesia are due to diminished levels of ...

Calorie Restriction, Longevity and Cognitive Function

Calorie Restriction

Calorie restriction, or caloric restriction (CR), is a dietary regimen thought to improve health and slow the aging process in some animals and fungi by limiting dietary energy intake below the average needs. CR is the only dietary intervention which has been documented to increase both the median and maximum lifespan in a variety of species, among them rodents, yeast, fishes and dogs. The life...

Insulin-like growth factor 1 receptor regulates hypothermia during calorie restriction.

When food resources are scarce, endothermic animals can lower core body temperature (Tb). This phenomenon is believed to be part of an adaptive mechanism that may have evolved to conserve energy until more food becomes available. Here, we found in the mouse that the insulin-like growth factor 1 receptor (IGF-1R) controls this response in the central nervous system. Pharmacological or genetic in...

Metabolic adaptation to protein restriction in insulin-dependent diabetes mellitus.

Eight normal subjects, four subjects with intensively treated insulin-dependent diabetes mellitus (IDDM), and six subjects with conventionally treated IDDM consumed a test meal of 0.5 g protein and 10 kcal per kg body weight, first while adapted to a conventional diet high in protein, and then again after 5 days of dietary protein restriction. Metabolic N balance (N consumed minus urea producti...
