Neurocutaneous Syndrome Related Research Tools

Neurocutaneous syndromes represent a heterogeneous group of genetic disorders characterized by abnormalities of the cutaneous and nervous systems. Neurofibromatosis type I (NF1), Tuberous sclerosis complex (TSC), and Sturge-Weber syndrome (SWS) are the three prototypical neurocutaneous disorders in which genetic mutations in the pathways regulating cell growth cause developmental dysfunctions of the brain, skin, and other organs. Possible contributors and molecular pathways involved in the three common neurocutaneous disorders are shown in Fig.1.

Fig.1 The scheme of the RAS/MAPK and mTOR pathways. (Stafstrom, 2017)

The mTOR signaling pathway begins at the cell membrane, where the receptors respond to growth factors and nutrient/energy molecules. Phosphatidylinositol triphosphate 3-kinase (PI3K) activates protein kinase B (AKT), a serine/threonine-specific protein kinase, and potent pro-survival and pro-oncogenic proteins. AKT directly phosphorylates TSC2 and inhibits its function. TSC2 inactivation by AKT reduces Ras homolog enriched in brain (Rheb). Overexpression of Rheb due to aTSC1 or TSC2 mutation leads to increased mTOR activation and excessive cell growth and proliferation.

Summary of the Popular Objects in Neurocutaneous Syndromes

Based on both unique molecular pathways for each syndrome and commonalities among syndromes, targeted therapies are emerging from the understanding of neurocutaneous disorders at the molecular level. Some key factors that may lead to neuronal hyperexcitability in these neurocutaneous disorders are listed in the table below.
