Spleen is scene for bug-fighting immune cell

摘要

The body's response to bacterial infection may rely on a newly discovered type of immune cell. Innate response activator B-cells (IRA-B) release a chemical that rallies neutrophils, immune cells that start attacking and engulfing bacterial invaders. While neutrophils are at the vanguard of immune defence, the primary role of B-cells was thought to be in organising the later "adaptive" immune response.
