APOE4 and the history of human disease
Apolipoprotein E, discovered in 1973, is derived from a polymorphic gene called ApoE that encodes for a signaling protein on a class of fatty proteins that primarily carry cholesterol and other molecules around the body. We find ApoE primarily on VLDL, very low-density lipoproteins and HDL, High density lipoproteins. It primarily helps to shuttle cholesterol from the periphery of the body back to the liver. ApoE proteins are also involved in neuronal signaling, neuroinflammation and glucose metabolism making them especially critical for brain activity. This is becoming a critical part of the story for understanding dementia and neurodegeneration. (Williams T. 2020) ApoE is most famous for an isoform, APOE4/4, being highly associated with Alzheimer’s dementia in modernity. Unfortunately, as we do with many things in medicine, we have been focused on this genetic protein variant as a net negative in humans because we look at things as black and white. Either good or bad. A binary choice. Rubish! …..

High Density Lipoprotein – We are going to take a deep look at this very complex biological topic. Bear with me as in the end it will all make more sense as to why “good cholesterol” is not inherently good or bad as much as it just is. Our lifestyle decisions are in effect making a biological process good or bad. That is my scientific understanding at this time. We also look at COVID19 and the effects on the heart this week.

Cholesterol Lipid Hypothesis Part IV – Endothelial Dysfunction
How does an artery clog? Let us recap a little at this time. 1) Cholesterol and lipoproteins are significant and necessary for pathology to develop but not the only player in heart disease and atherosclerosis. I believe that inflammation is the root cause of the problem driving the lipid imbalance and plaque formation. 2) Lipoproteins are produced and recycled every day in order to deliver energy to tissues around the body via triglycerides and are a part of the ancient innate immune system. They are primed and ready to fight all systemic pathogens that are trying to hurt us. 3) Your genetic makeup may dictate whether you produce and/or recycle more cholesterol/lipoproteins than are advantageous in our current environment….Plus a discussion on acne.
