“…ApoA1 is the main protein component of HDL, and a biomarker of cardiovascular disease [31], while ApoB is the main protein including plasma chylomicrons, verylow-density lipoprotein (VLDL) and LDL [32], which can be used as a biomarker of schizophrenia [33]. On the one hand, numerous studies have observed the mixed changes in ApoA1 and ApoB levels in patients with schizophrenia, such as an increase in ApoA1 [31,34,35] or ApoB [33,36,37] and reduction of ApoA1 [37,38], or ApoB [35]. On the other hand, ApoA1 and ApoB levels may be associated with cognitive decline [39,40], which has been indirectly verified by a number of mouse experiments [41,42].…”
