The HDL donates apolipoprotein C-II (APOC2) and apolipoprotein E (APOE) to the nascent chylomicron and, thus, converts it to a mature chylomicron (often referred to simply as "chylomicron").
Apolipoprotein E, a main apoprotein of the chylomicron, also studied for its involvement in Alzheimer's Disease risk.
In partnership with Abraham Kornzweig, Bassen identified Bassen-Kornzweig disease, a rare autosomal recessive disorder in which the body fails to produce chylomicrons, a low density lipoprotein (LDL) and very low density lipoprotein (VLDL).
