Q

How do PCSK9 inhibitors work?

A

In the liver…

  • Normally PCSK9 is secreted into the ECF, which then binds to the LDL-receptor on the cell surface.
  • The receptor is endocytosed by the cell and the PCSK9/LDL-receptor complex forces the LDL-receptor into the lysosome degradation pathway rather than the recycling pathway.
  • Binding to PCSK9 by PCSK9-inhibitors, therefore, increases the likelihood that LDL-receptors will be recycled, thus decreasing LDL serum concetrations.
