It focuses on a specific type of cells lining the wall of the third ventricle in the median eminence of the hypothalamus. This region acts both as a secretor of neuropeptides and as a sensor of the metabolic status of the periphery. These two functions imply a bidirectional physiological pathway: br...

Gonadotropin-releasing hormone (GnRH) neurons in the hypothalamus govern t...

Brief summary: Using a combination of expression studies in human embryos as well as functional studies in zebrafish and genetic sequencing of patient with congenital hypogonadotropic hypogonadism, this study identified a novel role for Jag1/Notch signaling in the development of GnRH neurons.GnRH neurons have a unique characteristic as they start life in the olfactory placode and then migrate into the hypothalamus during embryonic development, thanks to ...

Brief summary: This study identified a new role for GnRH in higher brain function using a rodent model of Down Syndrome. It reports for the first time an improvement of cognitive functions in patients with Down Syndrome treated with pulsatile GnRH.GnRH neurons are classically described as a population of neurons located in the hypothalamus and responsible for the activation and regulation of the hypothalamic-pituitary-gonadal axis. However, the recent de...

Brief summary: This study identified nitric oxide synthase 1 (NOS1) heterozygous missense variants in 6 patients with hypogonadotropic hypogonadism. Altered minipuberty and puberty as well as cognitive impairment were observed in NOS1 deficient mice.Nitric oxide (NO) is produced under the control of NO synthase in hypothalamic neurons. NO plays a crucial role in regulating gonadotropin-releasing hormone (GnRH) secretion, acting as a strong inhibitory sig...
