The primary interest of Dr. Yan Xiang's laboratory is host-pathogen interactions, with poxviruses as our model systems. Variola virus and molluscum contagiosum virus (MCV) are the only two members of poxvirus family that exclusively infect humans and cause human diseases. Variola virus is the causative agent of smallpox. A closely related poxvirus, vaccinia virus, serves as the vaccine for smallpox. 

However, the vaccination causes a relatively high level of immunization complications. MCV is still prevalent throughout the world. Unlike smallpox virus, MCV causes small, benign skin lesions in children and young adults and a more extensive disease only when there is a concurrent immunodeficiency such as AIDS. We are trying to understand the molecular mechanisms of poxviral pathogenesis by uncovering the functions of various poxviruses virulence factors.
