Abstract
The genus Morbillivirus in the family Paramyxoviridae contains many pathogens, which are important for medicine or veterinary medicine. Because each morbillivirus has restricted host range and serologically monotypic, the virus infection and transmission is effectively controlled by vaccinations and surveillance. Rinderpest virus has been eradicated in 2011, and elimination of measles virus progresses worldwide. Recently, a new cell receptor for measles virus, nectin4 was identified. Both SLAM, a molecule expressing on immune cells, and nectin4, a molecule expressing on epithelial cells, are important to infectivity and pathogenicity of the virus.
