Murine norovirus (MNV) infection can cause morbidity and mortality in immunocompromised mice, especially colonies in research laboratory. MNV also can infect and propagates in macrophages and dendritic cells which trigger atherosclerosis development through the accumulation of these cells followed by the formation of foam cells. Recently, MNV-4 infection was associated with an increase in aortic sinus lesion size in LDLR (low-density lipoproteins) and ApoE (Apolipoprotein E) mice, both are well established mouse models for atherosclerosis research. Therefore, this review is intended to summarize the impacts of MNV infection in these two mouse models of atherosclerosis. The findings from all the related studies are important in understanding the fundamental effect of MNV infection on atherosclerosis development. In addition, this information could provide insight to researchers on the evaluation to eliminate MNV infection in research facility to avoid any unintended effect in their research, particularly in-vivo studies involving mice.
