Another post-mortem study of subjects with BD (n = 10), SCZ (n = 9), MDD (n = 11), and HC (n = 14) found a reduction in the density of GFAP immunoreactive astrocytes in the amygdala of the MDD group compared to all other groups; however, there was no difference between SCZ, BD, and HC [36]. Here, GFAP is linked to Behcet disease.
