Human DNA shows traces of ancient battle between primate and pathogen
Salt Lake City UT (SPX) Dec 18, 2014
Examination of DNA from 21 primate species - from squirrel monkeys to humans - exposes an evolutionary war against infectious bacteria over iron that circulates in the host's bloodstream. Supported by experimental evidence, these findings, published in Science, demonstrate the vital importance of an increasingly appreciated defensive strategy called nutritional immunity. "We've known about nutritional immunity for 40 years," says Matthew Barber, Ph.D., first author and postdoctoral fellow in human ... read more
