Researchers Develop First Accurate Method to Assess Important Protein in MS, Other Diseases

Researchers at the University of Copenhagen and Rigshospitalet in Denmark have for the first time developed an accurate method to measure apolipoprotein M (apoM), a protein that is involved in several diseases like diabetes but also arteriosclerosis and sclerosis, disorders characterized by the stiffening of structures usually by replacement of the normal tissue by connective tissue. The study is entitled “Protein unfolding allows use of commercial antibodies in an apolipoprotein M sandwich ELISA” and was recently published in the Journal of Lipid Research.

The protein apoM circulates in the plasma attached to high-density lipoprotein (HDL) particles. ApoM is important for cholesterol metabolism and has been recently shown to transport the signaling lipid sphingosine-1-phosphate (S1P), which has been implicated in various inflammatory diseases such as rheumatoid arthritis and multiple sclerosis.

“We know that apoM is of importance to the development of arteriosclerosis and cardiovascular diseases. Previously, we have discovered that apoM carries a small fatty molecule, S1P, which plays a part in both diabetes and sclerosis. Whether or not apoM is of importance, remains to be seen, however, our new and secure measuring methods open up completely new perspectives on the research being conducted in these areas” said the study’s senior author Dr. Christina Christoffersen in anews release.
