To understand Mycobacterium leprae-peripheral nerve interaction, we have investigated the binding of M. leprae to rat peripheral nerve proteins in an in vitro model using 32P-phosphorylated proteins of the peripheral nerve. Intact M. leprae binds to a major phosphorylated protein of 28-30 kDa and, to a minor extent, to a few proteins of molecular weight 45-55 kDa. This binding was more specific for M. leprae since only insignificant binding was observed with other bacteria, such as M. bovis or Escherichia coli. M. leprae did not show binding to several phosphorylated proteins of the rat brain. The 28-30-kDa binding protein of the rat peripheral nerve was found to be a glycoprotein by concanavalin A-Sepharose column chromatography.

D010525 Peripheral Nerves The nerves outside of the brain and spinal cord, including the autonomic, cranial, and spinal nerves. Peripheral nerves contain non-neuronal cells and connective tissue as well as axons. The connective tissue layers include, from the outside to the inside, the epineurium, the perineurium, and the endoneurium.
