Condition: Down Syndrome · Cognitive Decline · Alzheimer Disease, Early Onset · Sponsor: Nelly Pitteloud
Down syndrome (DS) is the most common chromosomal disorder; with the increasing life expectancy, about 80% of DS adults reach age 65 years old. Early Alzheimer's disease (AD) is the most common cause of death within this population. DS individuals already show AD neuropathology by the age of 30, while it becomes clinically recognized in their late forties. DS subjects also exhibit olfaction defects in adulthood. To date, there is no treatment available for the cognitive or olfactory defects in DS. The development of an effective treatment targeting cognitive dysfunction in DS adolescents/adults would be warranted. GnRH, a decapeptide secreted by hypothalamic neurons is the pilot light of reproduction in all mammals. Pulsatile GnRH acts on the gonadotrophs via the GnRH receptor (GNRHR) in the pituitary gland to stimulate LH and FSH, which themselves will act on the gonads to produce gametes and steroids. However, GNRHR are also expressed in cerebral cortex, hippocampus, amygdala, habenula, olfactory structures, and adrenal gland, suggesting that GnRH may have a role beyond reproduction. Recently, GnRH has been shown to be involved in the process of ageing and lifespan control. Notably, in murine models, GnRH acts as an anti-ageing factor, independent of sex hormones. While ageing is characterized by hypothalamic inflammation and diminished neurogenesis, particularly in the hypothalamus and the hippocampus, GnRH was able to promote adult neurogenesis. The regulation of GnRH…
