Results suggest that, via astrocytes, IL-17A could promote glutamate excitotoxicity in multiple terms: by decreasing the astrocyte ability to uptake extracellular glutamate, due to a reduced gene expression of glutamate transporters (GLAST and GLT-1); by decreasing intracellular glutamate conversion into non-toxic glutamine; by potentiating glutamate exocytosis in a Ca2+ dependent manner

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
