Furthermore, in this study, Zhang et al. (2022) revealed that a biomarker panel of 13 lipids, Cer(d18:1/16:0), Cer(d18:1/24:1), Cer(d40:1), Cer(m18:0/20:0), Cer(m34:0+O), DG(21:5), LPE(18:1), LPE(20:4), PC(16:1/16:0), PE(P-16:0/22:6), PE(P-20:0/18:2), PE(37:2), and PE(8:0p/12:3), could provide reliable discrimination between BD and MDD patients [65]. Here, CBLN1 is linked to major depressive disorder.
