PCSK9 stimulates Syk, PKCδ, and NF-κB, leading to atherosclerosis progression independently of LDL receptor
This study found that higher levels of a protein called PCSK9 in the blood are linked to higher activity of inflammation-related molecules in immune cells, even when cholesterol levels are taken into account — which is exactly what the claim says.
