Intracellular trafficking of a dynein-based nanoparticle designed for gene delivery

Unit 1 of NANBIOSIS, Protein Production Platform (PPP) and the  Nanobiotechnology research group of CIBER-BBN in collaboration with the Universidade Estadual de Campinas and the Universidade de São Paulo have recently published, in the European Journal of Pharmaceutical Sciences, the results of the research devoted to the improvement of protein-only based nanoconjugates for gene therapy. The evaluated gene-therapy vehicle prototype  displayed a similar transfection efficiency to that of the commercial vector LipofectamineTM 2000.

Nanoparticles capable of bi-directional communication

The results of a research co-led by Ramón Martínez-Máñez, Scientific Director of Unit 26 of NANBIOSIS and CIBER-BBN have been published by Nature Communication last May 30th, showing how to prepare a nanoparticles chemical communication system using lactose. So far, his group had managed to establish communication between three nanoparticles but only in a unidirectional way. “We have managed to get a nanoparticle to send a chemical messenger to the second nanoparticle, who understands the message and sends another chemical messenger back to the first one. Upon receiving it, it performs an action, in this case releasing a dye,” explains Martínez-Máñezto Efefuturo.

This is a very important “basic” research due to the lack of proven results at the nanoscopic level. This research is the first step in getting the nanoparticles to work in a collaborative and coordinated way, anticipating a future of intelligent nanoparticle networks and advanced controlled release systems, drugs or complex systems based on nanotechnology.

The characterization of the system has been done with NMR unit of NANBIOSIS
