Fig 7. Schematic illustration of the relative distribution of lipid droplets between glial cell types and the localization of Dfabp.

LDs are concentrated in large clusters in the perinuclear region of glial cells but are not present at all in neurons (N). Specialized superficial cortex glial cells (CG) insulating neuroblasts (NB) and their daughter cells (asterisks) accumulating the highest amount of LDs. Neighboring subperineurial cells (SPG) establish septate junctions (SJ), while SPG and superficial cortex glial cells are connected to each other through adherens junctions (AJ). The Drosophila fatty acid binding protein (Dfabp) is expressed in LD accumulating superficial cortex glial cells and subperineurial (SPG) cells, and is localized in the cytosol and in the nucleus. NL: neural lamella, PG: perineural glia, NG: neuropil glia, ax: axon.
