Area of Science:

  • Molecular Biology
  • Cell Signaling
  • Immunology

Context:

  • NF-kappaB, a transcription factor family, is crucial for cellular responses.
  • Normally inactive in the cytoplasm, NF-kappaB is released by inhibitor degradation upon cellular stimulation.
  • Its activation impacts immunity, inflammation, cell proliferation, and apoptosis.

Purpose:

  • To review diverse NF-kappaB activation mechanisms, including novel pathways.
  • To detail the IKK-mediated signal transduction pathway for NF-kappaB activation.
  • To discuss NF-kappaB's role in tumorigenesis and its potential in drug screening.

Summary:

  • NF-kappaB activation involves IkappaB degradation, enabling nuclear translocation and gene regulation.
  • Alternative pathways involving lymphotoxin and CD40 ligand are highlighted.
