Serum SAP level increased in elderly patients with hyperlipidemia.
SAP deficiency reduced the plaque size in ApoE−/− mice.
SAP deficiency partially inhibited macrophage polarization toward M1 or M2 phenotypes and reduced TNF-α, IL-6, RANTES and ICAM1 expression.
Lack of SAP reduced the plaque size in ApoE−/− mice and foam cell formation by down-regulating CD36/FcγR-dependent pathway.
