Vaccine Against PCSK9 Improved Renal Fibrosis by Regulating Fatty Acid β-Oxidation.

ABSTRACT: Background Defects in the renal fatty acid β-oxidation pathway have been implicated in the development of renal fibrosis. Our group has developed a therapeutic vaccine targeting PCSK9 (proprotein convertase subtilisin/kexin type 9), named PCSK9Qβ-003. In this study, we investigated the potential effectiveness of the PCSK9Qβ-003 vaccine on hypercholesterolemia with renal fibrosis. Methods and Results The low-density lipoprotein receptor^+/- male mice fed with a high-cholesterol (1%) Western diet were randomly assigned into 4 groups: the sham group (or the control group), the phosphate-buffered saline group, the Qβ virus-like particles group and the PCSK9Qβ-003 vaccine group. Mice of the PCSK9Qβ-003 group were injected with the PCSK9Qβ-003 vaccine (100 μg/time) every 2 or 4 weeks.
