  "id": "MLC-T-CHM-010609",
  "term": "Secondary challenge",
  "field": "Chemistry",
  "definition": "The re-exposure of an organism to an antigen after an initial priming exposure, leading to a more rapid and potent immune response. This subsequent encounter stimulates memory lymphocytes, which proliferate and differentiate quickly to produce a heightened immune reaction. The secondary response is characterized by a faster onset and higher antibody titers than the primary response.",
