Tumor necrosis factor (TNF) triggers cell-specific responses via distinct intracellular pathways. This review summarizes current knowledge of these TNF-induced signaling pathways.

Area of Science:

  • Immunology
  • Cell Biology
  • Molecular Biology

Background:

  • Tumor necrosis factor (TNF) is a key proinflammatory cytokine involved in numerous physiological and pathological processes.
  • TNF regulates immunological reactions, with its functions often being cell type-specific.
  • Cellular responses to TNF depend on the specific intracellular signaling pathways activated by the cytokine.

Purpose of the Study:

  • To review and synthesize current knowledge on intracellular signaling pathways activated by TNF.
  • To explore the mechanisms underlying TNF-induced cellular responses.
  • To highlight commonly activated TNF signaling pathways across different cell types.

Main Methods:

  • Literature review of existing research on TNF signaling.

  • Analysis of studies investigating cell type-specific responses to TNF.
  • Synthesis of information on identified intracellular signaling cascades.

    • Main Results:

    • Several intracellular signaling pathways commonly activated by TNF have been identified.
    • The specificity of TNF-induced cellular responses is linked to the activation of distinct signaling pathways.
    • While cell type specificity is not fully elucidated, common pathways are frequently observed.

    Conclusions:

    • Understanding TNF-induced signaling pathways is crucial for comprehending its diverse roles.
    • Further research is needed to fully elucidate how cell type specificity is controlled by these pathways.
    • This review provides a consolidated overview of current insights into TNF signaling.
