title: Mycobacterium leprae binds to a major human peripheral nerve glycoprotein myelin P zero (P0).
abstract: We have previously shown that a major phosphorylated 25-kDa glycoprotein of the human peripheral nerve binds to Mycobacterium leprae. In the present study, we confirm that the 25-kDa glycoprotein of the human peripheral nerve is myelin P zero (P0) by immunoprecipitation and Western blot experiments using monoclonal antibodies to myelin P0. Immunohistochemical studies on human nerve using these antibodies to myelin P0 exhibited a strong immunoreactivity to the myelin and Schwann cells. Myelin P0 is a peripheral nerve specific protein; therefore it could likely be one of the key target molecules for M. leprae binding/internalization or even contact-dependent demyelination. This finding of M. leprae binding to myelin P0 adds to the present understanding on neural predilection of M. leprae.
