  "id": "MLC-T-CHM-005173",
  "term": "Helper T lymphocyte",
  "field": "Chemistry",
  "definition": "A type of T lymphocyte that orchestrates the adaptive immune response by activating and directing other immune cells, such as B cells and cytotoxic T cells. Upon recognizing an antigen presented by an antigen-presenting cell, these lymphocytes proliferate and differentiate into specialized subsets, releasing cytokines to modulate the immune system's activity. Helper T lymphocytes are characterized by the presence of the CD4 protein on their cell surface.",
