Nuclear factor kappa-B (NFkappaB) regulates inflammatory genes and is implicated in various diseases. This review explores NFkappaB

Area of Science:

  • Molecular Biology
  • Immunology
  • Cardiology

Background:

  • Nuclear factor kappa-B (NFkappaB) is a critical redox-sensitive transcription factor.
  • NFkappaB activation orchestrates inflammatory gene expression, impacting numerous pathological conditions.
  • Its role extends to apoptosis and cellular responses.

Purpose of the Study:

  • To review the fundamental regulation and activation mechanisms of NFkappaB.
  • To elucidate the cell biological effects and role of NFkappaB in apoptosis.
  • To discuss the involvement of NFkappaB in cardiovascular pathologies like ischemia-reperfusion injury, heart failure, atherosclerosis, and unstable coronary syndromes.

Main Methods:

  • Literature review of existing research on NFkappaB.
  • Analysis of NFkappaB's role in inflammation and apoptosis.

Related Experiment Videos

  • Examination of NFkappaB's involvement in cardiovascular disease pathophysiology.

    • Main Results:

    • NFkappaB activation drives pro-inflammatory gene transcription, including adhesion molecules, cytokines, and chemokines.
    • NFkappaB plays a dual role, inducing inflammation but also involved in endogenous myocardial protection via ischemic preconditioning.
    • Evidence links NFkappaB to the pathophysiology of ischemia-reperfusion injury, heart failure, atherosclerosis, and unstable coronary syndromes.

    Conclusions:

    • NFkappaB is a central regulator of inflammation and apoptosis with significant implications in cardiovascular diseases.
    • Despite its pro-inflammatory role, NFkappaB signaling is crucial for myocardial protection.
    • NFkappaB represents a potential therapeutic target for myocardial protection and treatment of related cardiovascular conditions.
