Tom Dayspring, M.D., FACP, FNLA – Part III of V: HDL, reverse cholesterol transport, CETP inhibitors, and apolipoproteins (EP.22)

"Here's something that's going to shock you: in an average person, anywhere from 30 to 60 percent of the cholesterol in that LDL particle arrived via an HDL particle." –Tom Dayspring

In this five-part series, Thomas Dayspring, M.D., FACP, FNLA, a world-renowned expert in lipidology, and one of Peter’s most important clinical mentors, shares his wealth of knowledge on the subject of lipids. In Part III, Peter and Tom dig into why “reverse cholesterol transport” is a lot more nuanced than what most of us are taught, lipid transport, apolipoproteins, and more. In addition, this episode highlights the complexity of HDL and a discussion about the CETP inhibitor trials.


We discuss:

  • Reverse cholesterol transport [1:40];
  • Lipid transportation, apolipoproteins, VLDL, IDL, and LDL particles [11:00];
  • Remnant lipoproteins and apoC-III [16:45];
  • Particles having sex: lipid exchange [28:00];
  • Cholesteryl Ester Transfer Protein (CETP) and CETP inhibitors [40:45];
  • 2006 CETP inhibitor trial: torcetrapib (Pfizer) [54:45];
  • 2012 CETP inhibitor trial: dalcetrapib (Hoffmann–La Roche) [56:15];
  • 2017 CETP inhibitor trials: evacetrapib (Eli Lilly) and anacetrapib (Merck) [58:00]; and
  • More.
