FFAR2 and Alzheimer disease: In contrast, GPR43-OE revealed a higher count of living neurons vs.AD (control:120.80 ± 13.22; AD:42.25 ± 3.35; GPR43-OE:73.25 ± 15.37; p < 0.05; Fig. 3E) in cortex and vs.AD (control:59.75 ± 3.71; AD:28.50 ± 2.18; GPR43-OE:43.50 ± 4.05; p < 0.05; Fig. 3F) in hippocampus by Nissl staining.
