GFAP and Alzheimer disease: The colocalization analysis of ApoE and GFAP in the GW3965 treated 3xTg-AD mice in the GL of DG, showed that the major expression of ApoE did not colocalize with GFAP positive cells, and also the colabeled cells for both GFAP and ApoE were mainly found in the SGZ (subgranular zone) as indicated by the threshold colocalization analysis (Fig 6C).
