1 -- The cell-mediated response has memory, and subsequent exposures to an antigen result in a more rapid and effective inflammatory response. This memory provides the basis for skin testing. A patient previously exposed to tuberculosis develops a more pronounced inflammatory response when minute amounts are injected under the skin. The other choices are characteristics of an antibody-mediated immune response.
