knockout of CD33 attenuated amyloid beta (Abeta) pathologyand improved cognition in 5xFAD mice, both of which were abrogated by additional TREM2 knockout. Differential gene expression in 5xFAD;CD33(-/-) microglia depended on the presence of TREM2, suggesting TREM2 acts downstream of CD33. Crosstalk between CD33 and TREM2 includes regulation of the IL-1beta/IL-1RN axis and a gene set in the "receptor activity chemokine"...

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.
