General description
1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-diethylenetriaminepentaacetic acid (18:0 PE-DTPA) comprises synthetic phospholipid derivative of ethanolamine.
This chelate is used for preparing MRI contrast agents.
Application
18:0 PE-DTPA (1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-diethylenetriaminepentaacetic acid (ammonium salt)) has been used to chelate liposome-based cationic adjuvant formulation (CAF01). It has also been used in the liposome preparation for imaging studies
Biochem/physiol Actions
1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-diethylenetriaminepentaacetic acid (18:0 PE-DTPA) or PE-DTPA binding and interaction with the Toll-like receptor-2 regulates immune response . PE-DTPA acts as a lipopolysaccharide antagonist and elicits rescue functionality in sepsis by blocking nuclear factor κ -light-chain-enhancer of activated B cells based transcription.

Specific targeting of inflammation remains a challenge in many pathologies, because of the necessary balance between host tolerance and efficacious inflammation resolution. Here, we discovered a short, 4-mer peptide which possesses antagonist properties towards CC chemokine receptor 2 (CCR2), but

The development of effective therapies for stroke continues to face repeated translational failures. Brain endothelial cells form paracellular and transcellular barriers to many blood-borne therapies, and the development of efficient delivery strategies is highly warranted. Here, in a mouse model

Toll-like receptor 2 (TLR2) initiates potent immune responses by recognizing diacylated and triacylated lipopeptides. Its ligand specificity is controlled by whether it heterodimerizes with TLR1 or TLR6. We have determined the crystal structures of TLR2-TLR6-diacylated lipopeptide, TLR2-lipoteichoic acid, and TLR2-PE-DTPA
