Abstract

Hybridization studies with [32P]cDNA probes revealed detectable amounts of mRNA for the low density lipoprotein (LDL) receptor in the central nervous system (CNS) of rabbits. mRNA levels were highest in the medulla/pons and spinal cord, which were the most heavily myelinated regions that were studied. Lower, but detectable levels were present in cerebral cortex, hypothalamus, thalamus, midbrain, and cerebellum. In the medulla/pons and spinal cord, the levels of receptor mRNA were in a range comparable to that detected in the liver. The levels of receptor mRNA in whole brain were constant from 3 days of age to adulthood and, thus, did not vary in proportion to the rate of myelin synthesis. LDL receptor mRNA in the CNS was produced by the same gene that produced the liver and adrenal mRNA as revealed by the demonstration of a deletion in the neural mRNA of Watanabe-heritable hyperlipidemic (WHHL) rabbits identical to the deletion in the LDL receptor gene of these mutant animals. Using antibodies directed against the bovine LDL receptor, we showed that LDL receptor protein is present in the medulla/pons of adult cows. The cell types that express LDL receptors in the CNS and the functions of these receptors are unknown.
