  "id": "MLC-T-CHM-002176",
  "term": "Cognate T cell",
  "field": "Chemistry",
  "definition": "A T lymphocyte that possesses a T-cell receptor capable of specifically recognizing and binding to a particular antigen when it is presented by an antigen-presenting cell (APC). This specific interaction is required to initiate an adaptive immune response against that antigen. For example, a cognate helper T cell provides activation signals to a B lymphocyte that has bound the same antigen, leading to antibody production.",
