New research shows babies’ immunological weak spot and strength

Posted by in category: biotech/medical

A pair of new studies led by researchers at Columbia University explains why babies get so many common respiratory infections and identifies a specialized cluster of immune cells found only in babies that help them better cope with new pathogens.

“We know little about how the immune system develops throughout life, and most of what we know about immune system development in children comes from animal studies,” says Donna Farber, Ph.D., an expert in immune system development at Columbia University Vagelos College of Physicians and Surgeons who led the research. “But mice develop much more quickly than humans and their immune systems are a bit different than ours.”

Using a trove of tissue samples from deceased pediatric organ donors, Farber’s team was able to pinpoint aspects of development that distinguish babies from adults.
