New model explains how immune cells recognize, destroy bacteria

The innate immune system serves as the body's specialized armed forces division, comprised of a host of defense mechanisms used to battle bacterial infections. Among the system's warriors are white blood cells including the specialized macrophages, which maintain constant surveillance for foreign intruders or pathogens, functioning as the body's first line of defense, poised to attack at barrier sites including the skin, lungs and intestines.
