Area of Science:

  • Immunology
  • Molecular Biology
  • Oncology

Context:

  • Tumor necrosis factor (TNF) mediates biological activities via TNF-R55 and TNF-R75 receptors.
  • Intracellular signaling pathways for TNF-induced apoptosis are increasingly understood.
  • Identification of TNF receptor-associated molecules provides further insight.

Purpose:

  • To explore novel TNF mutants with improved therapeutic profiles.
  • To investigate the potential of TNF gene transduction for cancer therapy.

Summary:

  • Biogenetic clarification of TNF mutants with higher affinity for TNF-R55 and lower affinity for TNF-R75.
  • These engineered TNF variants exhibit diminished adverse effects and augmented antitumor activity.
  • TNF gene transduction into lymphocytes and tumor cells reduces tumorigenicity and enhances host immunogenicity.
