Chronic kidney disease and lipid metabolism receptors

Lipids are very important molecules in the human body. Different types of lipids include fats and some vitamins. Lipids form the membranes in and around cells, store energy, and signal between cells. Lipids, like fats and oils, do not dissolve in water. To get them around the body they form complexes with proteins. These complexes include LDL and HDL.

Your doctor may have requested blood tests for these. They are important in cardiovascular disease. To get lipids into cells receptors must bind the lipoprotein complexes. Sometimes rather than supporting the cell, lipid uptake can cause stress and inflammation. This is why doctors often check the levels of LDL and HDL.

CD36 is a receptor for lipoproteins. We investigated the role of CD36 in chronic kidney disease (CKD). Breaking this receptor by changing the DNA that creates it protected against CKD. Similar protection happened with a small peptide inhibitor. This is important because it is easier to help patients by giving them a drug than by trying to change their DNA.
