PtdSer-based delivery systems and their utility in various disease conditions
| Carrier | Therapeutic agent delivered | Functional effect or mechanism of action | Indication or target | Reference |
|---|---|---|---|---|
| Liposomes | Prototypical gene (GFP plasmid) | Fusogenic property of PtdSer for enhanced DNA delivery | Gene delivery to lungs | [55] |
| PtdSer | Clearance of HIV-bound particles | Antiviral (HIV infection) | [54] | |
| Phosphatidic acid (PA) or combination PA + isoniazid | Reduction of bacterial load | Mycobacterium tuberculosis (MTB) infection | [42] | |
| SapC-DOPS | Saposin C | Tumor cell apoptosis, lysosomal cell death | Pancreatic cancer, brain tumor imaging, glioblastoma, lung cancer, neuroblastoma | [46,127–132] |
| Poly(lactic-co-glycolic acid) | LXR agonist | Reduced inflammation and number of CD68+ macrophages | Atherosclerosis | [48] |
| Carbon nanotubes | Cytochrome C | Disruption of endosomes and activation of the caspase cascade, apoptosis | Alveolar macrophages | [133] |
