These micrographs from layer 5 of the prefrontal cortex show microglia adjacent to oligodendrocytes from control brain (A) and from the SPPS subgroup (B–D). “Resting” microglia (A). Ameboid (activated) microglia (B). Dystrophic changes in microglia and oligodendrocytes: cytoplasm vacuolation, damaged mitochondria, accumulation of lipofuscin granules (C, D). Microglial cytoplasm contacts with oligodendrocyte nucleus (B, C, *). Focal lysis (L) of cytoplasm of oligodendrocytes adjacent to microglia (C, D). Mg, microglia; Ol, oligodendrocyte, m, mitochondria (arrows); V, vacuole (arrows), Lg, lipofuscin granule (arrows). (Scale bars = 1 µm).
