By: N. Muthusamy n, L. Sommerville n, A. Moeser n, D. Stumpo *, P. Sannes n, K. Adler n, P. Blackshear *, J. Weimer *, H. Ghashghaei  n

author keywords: aging; barrier function; Clca3; cerebral cortex; ependymal cells; lipid droplets; mucin; oxidative stress
MeSH headings : Aging / metabolism; Animals; Ependyma / cytology; Ependyma / metabolism; Homeostasis; Intracellular Signaling Peptides and Proteins / deficiency; Intracellular Signaling Peptides and Proteins / metabolism; Lipid Metabolism; Membrane Proteins / deficiency; Membrane Proteins / metabolism; Mice; Mucins / metabolism; Myristoylated Alanine-Rich C Kinase Substrate; Oxidative Stress; Prosencephalon / metabolism
TL;DR: It is demonstrated that metabolic and barrier functions in ECs decline significantly during aging in mice, and this work constitutes a conceptually new paradigm in the potential role of ECs in the initiation of various conditions and diseases in the aging brain. (via Semantic Scholar)

2011 journal article

Specification of a Foxj1-Dependent Lineage in the Forebrain Is Required for Embryonic-to-Postnatal Transition of Neurogenesis in the Olfactory Bulb

JOURNAL OF NEUROSCIENCE, 31(25), 9368–9382.

By: B. Jacquet n, N. Muthusamy n, L. Sommerville n, G. Xiao n, H. Liang n, Y. Zhang *, M. Holtzman *, H. Ghashghaei  n

MeSH headings : Animals; Forkhead Transcription Factors / metabolism; Mice; Mice, Knockout; Neurogenesis / physiology; Neurons / physiology; Olfactory Bulb / embryology; Olfactory Bulb / physiology; Prosencephalon / embryology; Prosencephalon / physiology
TL;DR: For the first time, this study identifies the time- and region-specific activity of a perinatal progenitor domain that is required for transition and progression of OB neurogenesis from the embryonic-to-postnatal periods. (via Semantic Scholar)
