| 产品描述: | LNP Lipid-8 (11-A-M) is an ionizable single-tail multi-head lipid that can be used as a lipid nanoparticle (LNP) to deliver siRNA to T cells without targeting ligands. LNP Lipid-8 is more selective for T cells than other cell types such as hepatocytes. LNP Lipid-8 selectively delivers siRNA/sgRNA to T cells (especially CD8+ T cells) through endogenous lipid transport pathways, and can enter cells and release RNA through endocytosis to achieve gene silencing. LNP Lipid-8 loaded with GFP siRNA (siGFP) significantly led to GFP gene silencing in mouse models. LNP Lipid-8 showed good efficacy and safety in both cells and animals, without obvious liver targeting and toxicity. LNP Lipid-8 can be used for RNA delivery research in the fields of tumor immunotherapy and T cell-mediated autoimmune diseases. |
