Class 3 semaphorins in the control of GnRH neuron development and diseases

GnRH secreting neurons are hypothalamic neuroendocrine cells that control reproductive axis. During development, they are thought to originate in the nasal placode and migrate associated with the vomeronasal axons to reach their final positions in the hypothalamus.
Developmental defects may be at the origin of genetic disorders such as Hypogonaditropic Hypogonadism (HH) and Kallmann syndrome (KS) whom mutated loci are largely unknown. By applying genetically modified mouse models, cellular models and mutational analysis we found that class 3 semaphorins play essential roles during different phases of GnRH neuron development and are implicated in the pathogenesis of some forms of HH and KS.
