Abstract

Insights

Interleukin-1 receptor 2 (IL1R2) is upregulated in lung adenocarcinoma (LUAD) and associated with poorer patient prognosis. Targeting IL1R2 may offer new therapeutic strategies for LUAD.

Area of Science:

  • Oncology
  • Immunology
  • Molecular Biology

Background:

  • Interleukin-1 receptor 2 (IL1R2) is part of the IL-1 receptor family and regulates the IL-1 pathway, implicated in tumorigenesis.
  • Elevated IL1R2 expression has been observed in various cancers, suggesting a potential role in malignancy.

Purpose of the Study:

  • To investigate the role of IL1R2 in lung adenocarcinoma (LUAD).
  • To evaluate IL1R2 as a prognostic biomarker and potential therapeutic target in LUAD.

Main Methods:

  • Immunohistochemistry was used to assess IL1R2 expression in LUAD tissues.
  • Bioinformatic analyses utilized UALCAN, Kaplan-Meier plotter, TIMER, STRING, and Metascape databases.
  • Correlations between IL1R2 expression, patient prognosis, and immune infiltrates were analyzed.

Main Results:

  • IL1R2 expression was significantly higher in LUAD tumor tissues compared to normal tissues.
  • Lower IL1R2 levels correlated with better patient prognosis.
  • IL1R2 expression showed positive correlations with B cells, neutrophils, CD8+ T cells, and exhausted T cells.
  • Functional analyses linked IL1R2 to IL-1 signaling and NF-KappaB pathways.

Conclusions:

  • IL1R2 plays a role in the progression and prognosis of LUAD.
  • Further research is needed to elucidate the underlying mechanisms of IL1R2 in LUAD.
