Correlation between mature BDNF (or proBDNF) in the brain and liver. (a) There was a negative correlation (r=−2.70, P=0.037) between mature BDNF in the parietal cortex and mature BDNF in the liver in all the subjects (N=60). (b) There was a positive correlation (r=0.288, P=0.026) between proBDNF in the cerebellum and proBDNF in the liver in all the subjects (N=60). BD, bipolar disorder; BDNF, brain-derived neurotrophic factor; MDD, major depressive disorder; SZ, schizophrenia.
