Battling Infection With Microbes

Jessica Stoller-Conrad
In the recent study the researchers found that beneficial gut bacteria were necessary for the development of innate immune cells—specialized types of white blood cells that serve as the body's first line of defense against invading pathogens.

A Changing View of Bone Marrow Cells

Kimm Fesenmaier
Using a novel microfluidic technique, researchers at Caltech have shown that, rather than simply replenishing immune cells after they become depleted, blood stem cells sense danger signals directly and quickly produce new immune cells.
