Fig. 2: Levels of expression of glial markers and myelin characteristics in nonhuman primate and human.

Comparison of the expression levels of astrocytic markers (GFAP & S100β), microglial markers (IBA1 & BRCA1), the oligodendrocytic marker (CNPase), and myelin characteristics (thickness & g-ratio) in nonhuman primates and humans of both sexes at midlife and old age. The abbreviations used are: MM midlife males/men, MF midlife females, MW midlife women, OM old males/men, OF old females, and OW old women.
