Interleukin-18 (IL-18) is a cytokine with unique immune-polarizing effects. Recent advances reveal its complex roles in diseases, suggesting potential therapeutic applications for IL-18 or its antagonists.

Area of Science:

  • Immunology
  • Molecular Biology

Background:

  • Interleukin-18 (IL-18) exhibits potent immunomodulatory effects, uniquely inducing T helper 1 or T helper 2 polarization.
  • Elevated serum IL-18 levels are observed in numerous human diseases, implicating it in immune-mediated pathogenesis.

Purpose of the Study:

  • This review discusses recent key advances in the immunobiology of IL-18.
  • Focuses on novel insights into IL-18's structure, signaling, and modulation of immune cells.

Main Methods:

  • Review of recent laboratory data and scientific reports.
  • Analysis of IL-18's role in T cells, dendritic cells, and natural killer cell function.
  • Examination of IL-18's involvement in specific diseases like graft-versus-host disease, diabetes, and sepsis.

Main Results:

  • Recent findings elucidate IL-18 structure and signaling pathways.
  • IL-18 modulates T cells, dendritic cells, and natural killer cells.
  • Paradoxical roles of IL-18 are highlighted in acute graft-versus-host disease, insulin-dependent diabetes, and sepsis.

Conclusions:

  • Emerging data highlight the complex and sometimes paradoxical roles of IL-18 in immune responses.
  • A deeper understanding of IL-18 immunobiology may facilitate the development of novel therapeutic strategies targeting IL-18 or its antagonists for immune-mediated diseases.
