Large-scale study probes how cells fight pathogens

(PhysOrg.com) -- Scientists have deciphered a key molecular circuit that enables the body to distinguish viruses from bacteria and other microbes, providing a deep view of how immune cells in mammals fend off different pathogens. The new research, which appears in the September 3 advance online edition of the journal Science, signifies one of the first large-scale reconstructions of a mammalian circuit and offers a practical approach for unraveling the circuits that underpin other important biological systems.
