AA-T3A-C12 is an anisamide ligand-tethered lipidoid (AA-lipidoid). AA-T3A-C12 mediates great RNA delivery and transfection of activated fibroblasts[1].
AA-T3A-C12/siRNA LNP 可增强 TGF-β 刺激的 3T3 成纤维细胞对 siRNA LNP 的摄取[1]。
AA-T3A-C12 LNP 可在活化的成纤维细胞中实现较强的基因敲低[1]。
AA-T3A-C12/siHSP47 LNP (siRNA 剂量为 5 μg/小鼠,静脉注射,每周两次,持续 2 周) 显着下调纤维化小鼠中的 HSP47 表达[1]。
| Animal Model: | CCl4-induced fibrotic mice[1] |
| Dosage: | siRNA dose of 5 μg/mouse |
| Administration: | i.v., twice weekly for 2 weeks |
| Result: | led to a 65% knockdown of HSP47 (in liver) compared to PBS treatment. |
