| Research Abstract |
The interaction between dystroglycan in Schwann cell and laminin in the basement membrane is crucial for the myelination of peripheral nerve. We generated LARGE transgenic mice in which this interaction is greatly enhanced. In the peripheral nerves of these mice, the expression of some genes related to myelination was altered. We crossed LARGE transgenic mice with dy2J mice, which exhibit dysmyelination of the peripheral nerve, however the defects in myelination were not ameliorated. Since the peripheral nerve affects the regeneration of the skeletal muscle via neuromuscular junction, we examined the regeneration of dy2J mice skeletal muscles. We demonstrated that the muscle regeneration was suppressed by the overexpression of LARGE in these mice.
