Significant negative correlations were also found between the serum levels of AOPPs and the PL content of total LDL (LDL-PL/LDL-apoB) in the HVs and patients with MS, as well as the PL content of LDL subclasses 2–6 in HVs and subclasses 1–6 in patients with MS. This evidence concerns the gene APOB and myeloid sarcoma.
