Acute dietary methionine restriction triggers cell cycle arrest and reversible growth defects in the neocortex Molecular biology; Neuroscience

Last part of PhD is online now! All credit goes to #DAVY lab members and collaborators :)

Questions arising:
1. How a developing organ sets up metabolism-dependent growth pattern?
2. If developmental time and trajectories are plastic, who counts the neuronal numbers (expected) during neurogenesis?

First 🦋 post! Very excited to share our lab's latest work exploring the shared and divergent aspects of human astrocyte development and glioblastoma. This effort spans many fields from developmental #glial biology to #stem cells and #tumor biology. rdcu.be/d5ADz A 🧵

Sex-specific astrocyte regulation of spinal motor circuits by Nkx6.1 Astrocytes play essential roles in functioning neuronal circuits and are regulated by regional transcription factors (TFs). Bosquez-Huerta et al. found that the TF Nkx6.1 is specifically expressed in astrocytes of the ventral spinal cord and that its deletion results in sex-specific effects on astrocyte morphology and spinal motor circuits.

Very interesting stuff: sex differences intersect with region-specific transcriptional programs to regulate #astrocyte function www.cell.com/cell-reports...

some great starter packs for the #glia, #astrocyte, #oligodendrocyte, #microglia, #neuro researcher: gliasky, astrocytesky, microglia
But if you also like interactions between celltypes, please help this starter pack get started. Maybe someone can connect all of us in a feed?
