The DAP12 adapter protein, primarily on myeloid and natural killer (NK) cells, can both activate and suppress immune cell functions. This review explores its dual role in regulating immune responses.

Area of Science:

  • Immunology
  • Cell Biology
  • Molecular Biology

Background:

  • DAP12 is an adapter protein expressed on myeloid and natural killer (NK) cells.
  • It associates with various cell surface receptors, influencing immune cell activity.

Purpose of the Study:

  • To review the dual functionality of DAP12.
  • To present evidence for DAP12's role in both activating and suppressing NK cell functions.

Main Methods:

  • Literature review of existing studies on DAP12.
  • Analysis of experimental data demonstrating DAP12's regulatory roles.

Main Results:

  • DAP12 has been predominantly characterized for activating myeloid and NK cell effector functions.
  • Recent findings indicate DAP12 can also inhibit myeloid cell functions.

  • Evidence suggests DAP12 can suppress as well as activate NK cells.

    • Conclusions:

    • DAP12 exhibits dual functionality, acting as both an activator and suppressor of immune cells.
    • Understanding DAP12's complex roles is crucial for deciphering immune regulation and developing targeted therapies.
