MetabolomicsLipid-accumulated reactive astrocytes promote disease progression in epilepsy (Mice lipidomics)

Reactive astrocytes play an important role in neurological diseases, but their molecular and functional phenotypes in epilepsy are unclear. Here, we show that in patients with temporal lobe epilepsy (TLE) and mouse models of epilepsy, excessive lipid accumulation in astrocytes leads to the format...

MetabolomicsTargeted polyamine metabolomics of ATP13A4-deficient cellular and mouse models

ATP13A4 is a polyamine transporter enriched in astrocytes that regulates extracellular polyamine homeostasis. This study contains targeted LC-MS/MS metabolomics data from ATP13A4-deficient cellular and mouse models, including C8-D1A astrocytic cells, astrocyte-conditioned medium, mouse cortex, pl...

ProteomicsPerturbations of the proteome in primary astrocytes from the hSOD1(G93A) ALS mouse model
Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease whose pathophysiology is largely unknown. Despite motor neuron death is recognized as the key event in ALS, astrocytes dysfunctionalities and neuroinflammation were demonstrated to accompany and probably even drive motor ...

TranscriptomicsDIRECT CONVERSION OF FIBROBLASTS INTO FUNCTIONAL ASTROCYTES BY DEFINED TRANSCRIPTION FACTORS
Direct cell reprogramming has enabled the direct conversion of skin fibroblasts into functional neurons and oligodendrocytes using a minimal set of cell lineage-specific transcription factors. This approach has substantial advantages since it is rapid and simple, generating the cell type of interest...

TranscriptomicsToward a Better Understanding of Potential Roles of Astrocytes in HIV-1-associated Neurocognitive Disorders
We present a microarray analysis of primary mouse astrocytes exposed to HIV-1 in culture. Results are compared with previous genomic studies of HIV-1 effect in human astrocytes and human and macaque brains. Day-two neonatal mouse astrocytes were exposed in triplicates to cell-free HIV-1/NL4-3 at m.o...

TranscriptomicsA Transcriptome Database for Astrocytes, Neurons, and Oligodendrocytes
A Transcriptome Database for Astrocytes, Neurons, and Oligodendrocytes: A New Resource for Understanding Brain Development and Function Understanding the cell-cell interactions that control CNS development and function has long been limited by the lack of methods to cleanly separate astrocytes, neu...

TranscriptomicsRNA-seq of mouse astrocytes in monoculture and co-cultured with rat neurons (both inactive and active).
Neurons induce a dramatic transformation in developing astrocytes, causing them to develop a complex stellate morphology resembling their appearance in vivo. However, the transcriptional changes that accompany this transformation are not known, nor are the signalling mechanisms responsible. Similarl...

TranscriptomicsLysosomal and phagocytic activity is increased in astrocytes during the progression of amyotrophic lateral sclerosis
The aim of the present study is to combine LCM and microarray analysis to study how astrocytes in the spinal cord of transgenic SOD1 G93A mice and their non-transgenic (NTg) littermates respond to stimuli determined by the presence of the human mutant protein throughout the evolution of the disease ...

TranscriptomicsIn vitro caloric restriction induces protective genes and functional rejuvenation in senescent SAMP8 astrocytes
Astrocytes are key cells in brain aging, helping neurons to undertake healthy aging or otherwise letting them enter into a spiral of neurodegeneration. We aimed to characterize astrocytes cultured from senescence-accelerated prone 8 (SAMP8) mice, a mouse model of brain pathological aging, along with...
