基于siRNA的传递系统的合理设计,以有效治疗大脑疾病

Source: Ullah, I., et.al. A Positioning Device for the Placement of Mice During Intranasal siRNA Delivery to the Central Nervous System. J. Vis. Exp. (2019)This video demonstrates a precise intranasal administration technique for delivering neuron-targeting peptide-siRNA complexes to the mouse brain using a specialized positioning device. Anesthetized mice are secured in a head-down-and-forward position to optimize siRNA inhalation while preventing lung drainage. The targeting peptide...

The goal of this protocol is to use cationic/anionic liposomes with a neuro-targeting peptide as a CNS delivery system to enable siRNA to cross the BBB. The optimization of a delivery system for treatments, like siRNA, would allow for more treatment options for prion and other neurodegenerative diseases.

Delivery remains the main challenge for the therapeutic implementation of small interfering RNA (siRNA). This protocol involves the use of a multifunctional and biocompatible siRNA delivery platform, consisting of arginine and polyethylenimine grafted porous silicon...

Here, we present a protocol using a mouse positioning device that enables the appropriate placement of mice for the intranasal administration of a brain-targeting peptide-siRNA formulation enabling effective gene silencing in the central nervous...

An exosome is a new generation of drug delivery carriers. We established an exosome isolation protocol with high yield and purity for siRNA delivery. We also encapsulated fluorescently labelled non-specific siRNA into exosomes and investigated the cellular uptake of siRNA-loaded exosomes in cancer...

We present a technique for localized administration of drugs through the trans-tympanic route into the cochlea. Drug delivery through this route would not interfere with the anti-cancer efficacy of the chemotherapeutic drugs such as...
