我们报告如何二聚体的细胞穿透肽达特,dfTAT,穿透活细胞逃逸内体,特别是高效率。通过介导内体渗漏,dfTAT还在简单的共孵育程序后将蛋白质递送到培养的细胞中。在培养物中的大多数细胞中实现胞质递送,并且仅相对少量的材料保持被捕获在内体内。递送不需要dfTAT和蛋白质之间的结合相互作用,可以一次递送多个分子,并且可以重复递送。值得注意的是,dfTAT介导的递送不会明显影响细胞活力、增殖或基因表达。这种新的递送策略对于基于细胞的测定、细胞成像应用和细胞的离体操作应该是非常有用的。
We report on how a dimer of the cell-penetrating peptide TAT, dfTAT, penetrates live cells by escaping from endosomes with a particularly high efficiency. By mediating endosomal leakage, dfTAT also delivers proteins into cultured cells after a simple co-incubation procedure. Cytosolic delivery is achieved in most cells in a culture and only a relatively small amount of material remains trapped inside endosomes. Delivery does not require binding interactions between dfTAT and a protein, multiple molecules can be delivered at once, and delivery can be repeated. Remarkably, dfTAT-mediated delivery does not noticeably impact cell viability, proliferation, or gene expression. This new delivery strategy should be extremely useful for cell-based assays, cellular imaging applications, and the ex vivo manipulation of cells.
