In a preprint* research paper recently uploaded to the bioRxiv server, researchers at Washington University investigated how the exposome can mediate immune function in house mice, probably the most widely used model systems for in vivo immunological experimentation. Mice were sequentially inoculated with six different viral pathogens from formative years (neonatal) stages, following which their […]
