Breg
n.— «In the past few years, researchers have discovered that certain B cells appear to share with regulatory T cells—fondly known as Tregs—the responsibility for keeping the immune system under control. Like Tregs, these B cells, which some experts have named regulatory B cells, or Bregs, release anti-inflammatory molecules and can forestall autoimmunity when infused into mice.» —“Take-Charge B Cells Create a Buzz” by Mitch Leslie Science July 10, 2009.
