Proliferation control in neural stem and progenitor cells

Key Points

  • Unlike in other organs, changes in cell numbers in the brain cannot be compensated by changes in cell size. This explains why the brain is particularly sensitive to defects in cell division and requires specific proliferation control mechanisms.

  • Drosophila melanogaster neural stem cells and mammalian cortical progenitors have emerged as the key model systems to study proliferation control in the brain.

  • In D. melanogaster, the segregating determinants NUMB, Prospero (PROS) and Brain tumour (BRAT) establish differential proliferation control in the two daughter cells of neural progenitors. In mammals, the asymmetric inheritance of apical and basal processes, asymmetry between the two centrosomes and interactions between the daughter cells through Notch signalling act redundantly to establish unequal cell fates.

  • D. melanogaster neural stem cells pass through distinct temporal stages, starting with their activation by insulin receptor signalling through the expression of a temporal transcription factor cascade to a switch in metabolic activity that ultimately triggers their shrinkage and differentiation.

  • In mammals, homologues of the D. melanogaster temporal cascade seem to act in conjunction with distinct events, such as the switch from neurogenesis to gliogenesis, which is dependent on the JAK–STAT (Janus kinase–signal transducer and activation of transcription) and Notch pathways.

  • Metabolic regulation plays a crucial role in proliferation control in both D. melanogaster neural stem cells and in adult mammalian neurogenesis.

  • Defects in proliferation control can lead to diseases such as microcephaly or megalencephaly.

Abstract

Neural circuit function can be drastically affected by variations in the number of cells that are produced during development or by a reduction in adult cell number owing to disease. For this reason, unique cell cycle and cell growth control mechanisms operate in the developing and adult brain. In Drosophila melanogaster and in mammalian neural stem and progenitor cells, these mechanisms are intricately coordinated with the developmental age and the nutritional, metabolic and hormonal state of the animal. Defects in neural stem cell proliferation that result in the generation of incorrect cell numbers or defects in neural stem cell differentiation can cause microcephaly or megalencephaly.

This paper shows that D. melanogaster NSPCs in the embryo-to-larva transition exit from quiescence in response to larval feeding. Larval feeding is sensed by the fat body, which then stimulates the production of insulin-like peptides by glial cells that in turn activate the TOR pathway in neuroblasts, inducing neuroblast growth and proliferation.
