Many viruses including mouse hepatitis virus, corona, measles, and sidbis viruses are known as causative virus of inducing demyelination which means destruction of myelination in nervous system of mice. The purpose of this study is to investigate processing of myelination by co-culture of Schwann cells and neuronal cells and demyelination induced by infection of sindbis virusin rat. Schwann cells and neuronal cells from dorsal root ganglion (DRG) in embryos (E16) of rat were cultured in vitro respectively. The purified neuronal cells with anti-mitotic agents and purified Schwann cells were co-cultured. After that, infection of sindbis virus into this myelinated co-culture system was performed. Myelination and demyelination process were observed using antibody of myelin basic protein meaning presence of myelination.We identified myelination and demyelination processing using antibody of peripheral myelin protein 22 (PMP 22) meaning presence of myelinated neuron. This study was supported by the Basic Research Program through the National Research Foundation (NRF) funded by the Ministry of Science, ICT & Future Planning (NRF-2015R1C1A1A01053484 and 2017R1A2B3005753).

The dorsal root ganglion (DRG) was isolated from mouse embryos and Schwann cells and neuronal cells were cultured in vitro. The neurons and Schwann cells were cultured separately and the two kinds of cells were cultured together for three weeks. Generation of myelination was confirmed by transmission electron microscope and confocal microscope using a myelinaion protein, myelin protein zero (MPZ) antibody. The sindbis virus was infected for three days in the myelinated culture cells and then demyelination was carried out. The process of demyelination was also confirmed by transmission electron microscopy and confocal microscopy using myelin protein zero (MPZ) antibody. The study was supported by a Basic Research Program through the National Research Foundation (NRF) funded by the Ministry of Science and Technology, ICT and Future Plans (NRF-2016R1A2B4016552 and 2017R1A2B3005753).
