Immunohistochemical Localization of 2′,3′‐Cyclic Nucleotide 3′‐Phosphodiesterase and Myelin Basic Protein in the Central Nervous System of the Jimpy and the Normal Mouse

Abstract
We describe the immunohistochemical localization of 2′,3′‐cyclic nucleotide 3′‐phosphodiesterase (CNPase) and myelin basic protein (MBP) in CNS of the jimpy mutant mouse which is characterized by dys‐ and demyelination. In controls, the CNPase and MBP were localized exclusively in white matter in the CNS. The jimpy mutant mice were severely affected: A very weak reaction was observed in the white matter. Very few CNPase‐ and MBP‐positive myelin sheaths were observed, and some degradation products were also observed after reaction with antisera against both CNPase and MBP. The immunohistochemical reaction in the jimpy mice showed a similar localization in both CNPase and MBP.
