Autoaggressive T-cells specific for myelin proteins like proteolipid protein (PLP) and myelin basic protein (MBP) are thought to play a major role in the pathogenesis of demyelinating diseases of the central nervous system (CNS). 2',3'-cyclic nucleotide 3'-phosphodiesterase (CNPase) is the third most abundant myelin protein in the CNS. Due to lack of supply with enough CNPase of sufficient purity its immunologic properties have not been studied yet. We subcloned a human CNPase cDNA and expressed human recombinant CNPase (rh-CNPase) in E. coli. Purification of the protein was achieved by Ni2+-chelating chromatography. Furthermore we describe for the first time several rh-CNPase specific T-cell lines from a multiple sclerosis patient and a healthy control.
