NPFFR1: A Novel Regulator of Energy Homeostasis and Mental Health
Introduction
Neuropeptide FF receptor 1 (NPFFR1) is a G protein-coupled receptor that plays a critical role in regulating energy homeostasis and mental health. This blog post explores the description, associated diseases, an interesting statistic, references, and additional information on the latest research related to NPFFR1.
Description
NPFFR1 is a member of the opioid-like receptor family, which binds to multiple neuropeptides, including neuropeptide FF (NPFF) and neuropeptide AF (NPAF). NPFF and NPAF are endogenous peptides that are widely distributed in the central and peripheral nervous systems, where they exert various physiological and behavioral effects.
NPFFR1 is expressed in a variety of tissues and organs, including the hypothalamus, amygdala, hippocampus, and liver. In the hypothalamus, NPFFR1 is involved in regulating appetite, energy expenditure, and glucose metabolism. In the amygdala and hippocampus, NPFFR1 is implicated in modulating emotional responses and memory formation.
Associated Diseases
Disruptions in NPFFR1 signaling have been linked to several human diseases, including:
- Obesity: NPFFR1 deficiency has been associated with increased food intake, weight gain, and obesity in animal models and humans.
- Anorexia nervosa: Reduced NPFFR1 expression has been observed in individuals with anorexia nervosa, a severe eating disorder characterized by excessive food restriction.
- Depression: Dysregulation of NPFFR1 signaling has been implicated in the pathophysiology of depression, a mood disorder characterized by persistent sadness and loss of interest.
- Schizophrenia: Altered NPFFR1 expression and function have been reported in individuals with schizophrenia, a severe mental illness characterized by hallucinations, delusions, and impaired social functioning.
Did you Know ?
A recent study found that individuals with obesity have a significantly lower expression of NPFFR1 in the hypothalamus compared to lean individuals, suggesting that NPFFR1 deficiency may contribute to the development of obesity.
