Brain ischemia in young mice increased at day 4 the microglial mRNA expression of Adipophilin (Plin2), Perilipin (Plin3), Hypoxia‐Inducible Lipid Droplet‐Associated (Hilpda), granulin precursor (Grn), Abhydrolase Domain Containing 5, Lysophosphatidic Acid Acyltransferase (Abhd5), Synaptosome Associated Protein 23 (Snap23), and lipoprotein lipase (Lpl; Fig 2A). The gene discussed is GRN; the disease is brain ischemia.
