PY - 2017 T2 - The Big Picture: Histology AB - The immune system protects the body against invasion by microorganisms, removes tissues damaged by trauma, and eliminates malignant growths. Recognizing these problems requires detecting foreign or unexpected molecules, called antigens, against the background of self-molecules. This recognition is accomplished by membrane-bound antigen receptors on immune system cells. When antigen receptors bind an antigen, these cells initiate effector responses to manage the problems.
