Mouse embryonic stem cells – a new cellular system for studying the equine infectious anemia virus <i>in vitro</i> and <i>in vivo</i>

Abstract

The complexity of the pathogenesis and insufficient knowledge about the slow retroviral infections, which include equine infectious anemia, necessitates finding an adequate laboratory model for the study of the infection process and immunogenesis to create means of prevention and treatment of diseases. Data about strains and cellular tropism of the virus are discussed. It was shown that mouse embryonic stem cells (ESCS) exhibited unique properties and characteristics. In contrast to fibroblasts and other cell types, these cells can be considered as a new cell system for studying EIAV in vitro and in vivo. Under differentiation-inducing conditions they are able to reproduce in vitro embryogenesis cells and form cells of three germ layers. Differentiation of mouse ESCs in the direction of hematopoiesis could contribute new knowledge and understanding of viral tropism EIAV in vitro. ESC can be returned back to the early pre-implantation embryo. Once in the germ cell environment, they participate in the formation of tissues and organs of the developing fetus. Thus, the adaptation of the mouse ESC to the equine EIAV through genetic transformation makes it possible to get closer to the creation of a laboratory model for the study of the in vivo immune response in the lentiviral infection.
