Neural Progenitor Cells (NPCs) are multipotent cells that are able to self-renew and differentiate into neurons. The size of the initial pool of NPCs during the brain development strongly affects the number of neurons that compose cortical multi-layer during development. Gonadal hormones can influence the balance between self-renewal and differentiation processes. Herein, we investigated the role of dihydrotestosterone (DHT), the active metabolite of testosterone, in the regulation of NPC stemness and differentiation.

The serpinopathies are human pathologies caused by mutations that promote polymerisation and intracellular deposition of proteins of the serpin superfamily, leading to a poorly understood cell toxicity. The dementia FENIB is caused by polymerisation of the neuronal serpin neuroserpin (NS) within the endoplasmic reticulum (ER) of neurons.
