Interleukin-18 (IL-18) is a key regulator of immune responses, found in chronic inflammation, autoimmune diseases, cancers, and infections. This review details IL-18 biology and its role in human diseases like autoimmunity and infection.

Area of Science:

  • Immunology
  • Molecular Biology
  • Cytokine Research

Background:

  • Interleukin-18 (IL-18) is a cytokine involved in immune regulation.
  • IL-18 is implicated in various conditions including autoimmune diseases, cancers, and infections.
  • IL-18 was initially identified as an interferon-gamma (IFN-gamma)-inducing factor.

Purpose of the Study:

  • To review the fundamental biology of Interleukin-18 (IL-18).
  • To examine the effector and regulatory functions of IL-18 in human diseases.
  • To explore IL-18's role in autoimmunity and infectious diseases.

Main Methods:

  • Literature review of IL-18's biological functions and disease associations.
  • Analysis of IL-18's molecular characteristics, including precursor and mature protein structures.

  • Comparison of murine and human IL-18 sequences.
  • Main Results:

    • IL-18 is a member of the IL-1 cytokine superfamily and a critical regulator of innate and acquired immunity.
    • IL-18 expression is observed in chronic inflammatory sites, autoimmune conditions, cancers, and infectious diseases.
    • Both murine and human IL-18 share significant sequence homology and possess unusual N-terminal leader sequences.

    Conclusions:

    • Interleukin-18 (IL-18) plays a significant role in immune responses and various human diseases.
    • Understanding IL-18's biology is crucial for investigating its therapeutic potential in autoimmunity and infection.
    • Further research into IL-18 mechanisms can inform disease management strategies.
