General description

Inositol phospholipid species are membrane-bound signaling molecules that have been implicated in almost all aspects of cellular physiology, including cellular growth, metabolism, proliferation, and survival.

Application

18:0-20:4 PI or 1-stearoyl-2-arachidonoyl-sn-glycero-3-phosphoinositol (ammonium salt) has been used:
  • as a negative control to evaluate the specificity of the interaction between cholesterol sulfate and receptor Mincle by surface plasmon resonance (SPR) experiment
  • as a test lipid in liposomes harboring candidate triggering receptor expressed on myeloid cells 2 (TREM2) ligands, to assess TREM2 stimulation
  • as a reference in liquid chromatography tandem mass spectrometry (LC-MS/MS) analysis to identify PI(18:0/20:4) in cancer tissue-originated spheroids (CTOSs) extraction

Sterile (noninfected) inflammation underlies the pathogenesis of many widespread diseases, such as allergies and autoimmune diseases. The evolutionarily conserved innate immune system is considered to play a key role in tissue injury recognition and the subsequent development of sterile inflammation;
