Inflammation 'on switch' also serves as 'off switch'

A study by NC State researchers found that a protein called TAB2 activates inflammation but also brings together molecules to turn it off. This finding challenges previous understanding of the protein's role in immune-system responses.

Team finds childhood clues to adult schizophrenia
