本文描述了一种方法,通过该方法将细胞不可渗透的分子封装在染料敏化的脂质纳米胶囊中,以通过内吞作用递送到细胞中。一旦进入细胞内部,这些分子就会从脂质纳米胶囊中释放到细胞质中,这是由远红(645 nm)激光发出的单个纳秒脉冲引起的。我们证明了这种方法与CHO-M1细胞中的第二信使IP 3的细胞内释放,并报告说,从细胞的钙反应从持续增加到瞬时尖峰时,IP 3释放的平均数量减少到低于50个分子/纳米胶囊。我们还证明了23 kDa AGT融合蛋白到Ba/F3细胞中的传递,以抑制凋亡途径中的关键球员BCR-ABL。我们发现,平均约8个分子的抑制剂足以诱导大多数Ba/F3细胞的凋亡。
This paper describes a method by which molecules that are impermeable to cells are encapsulated in dye-sensitized lipid nanocapsules for delivery into cells via endocytosis. Once inside the cells, the molecules are released from the lipid nanocapsules into the cytoplasm with a single nanosecond pulse from a laser in the far red (645nm). We demonstrate this method with the intracellular release of the second messenger IP3 in CHO-M1 cells, and report that calcium responses from the cells changed from a sustained increase to a transient spike when the average number of IP3 released is decreased below 50 molecules per nanocapsule. We also demonstrate the delivery of a 23 kDa AGT fusion protein into Ba/F3 cells to inhibit a key player BCR-ABL in the apoptotic pathway. We show that an average of ~ 8 molecules of the inhibitor is sufficient to induce apoptosis in the majority of Ba/F3 cells.
