En este vídeo Jose Francisco Guillen Caro, Responsable de garantía de calidad del CCMIJU presents the Jesús Usón Minimum Invasion Surgery Center in Cáceres and, especially, the UMISC units that integrate NANBIOSIS, as well as the services and tests they perform, which are certified as GLP
In this video, Jesús Izco Ex. Director of NANBIOSIS, presents NANBIOSIS as one of the 29 ICTS that currently make up the national ICTS map. It consist consists of 27 units grouped into five platforms which ofer their services under a single contact point and develops on demand projects and cutting edge biomedical solutions in different biomedical applications such as biosensors, live image, contrast agents, therapeutic agents, regenerative medicine, drug delivery, among others.
NANBIOSIS makes available its youtube channel with informative videos about the ICTS-NANBIOSIS and the activity of some of its research units and platforms, as well as its Cutting-edge Biomedical Solutions and Nanomedicines Cascade Characterizations
Jaume Veciana and Imma Ratera (NANBIOSIS U6 Biomaterial Processing and Nanostructuring Unit) have supervised Manuel Souto’s PhD thesis entitled “Multifunctional Materials based on TTF-PTM dyads: towards new Molecular Switches, Conductors and Rectifiers”.
The School for Doctoral Studies, together with UAB Alumni, organises an event every semester for the award of PhD degrees and PhD special prizes. With 66 PhD programmes, the UAB is one of the leading Catalan universities in the production of theses and generates approximately a third of the doctoral theses that are defended in the Catalan university system each year. The PhD special prizes confer value to theses which have received the qualification of excellence “Cum Laude” and which, having been proposed by the Admissions Committee of each academic programme, stand out for their contribution and advance in the different areas of our University.The prizes are awarded per academic year, in accordance with PhD regulations and with the criteria specified in each PhD programme.
Researchers of NANBIOSIS U7 Nanotechnology Unit are coauthors of the article “Involvement of Cellular Prion Protein in α-Synuclein Transport in Neurons” by Molecular Neurobiology
The cellular prion protein, encoded by the gene Prnp, has been reported to be a receptor of β-amyloid. Their interaction is mandatory for neurotoxic effects of β-amyloid oligomers. In this study, we aimed to explore whether the cellular prion protein participates in the spreading of α-synuclein. Results demonstrate that Prnp expression is not mandatory for α-synuclein spreading. However, although the pathological spreading of α-synuclein can take place in the absence of Prnp, α-synuclein expanded faster in PrPC-overexpressing mice. In addition, α-synuclein binds strongly on PrPC-expressing cells, suggesting a role in modulating the effect of α-synuclein fibrils.

Researchers of NANBIOSIS U7. Nanotechnology Unit, are coauthors of the article “Nanopatterns of Surface-Bound EphrinB1 Produce Multivalent Ligand–Receptor Interactions That Tune EphB2 Receptor Clustering” published by NanoLetters, ACC Publications.
The authors present a nanostructured surface able to produce multivalent interactions between surface-bound ephrinB1 ligands and membrane EphB2 receptors. They have created ephrinB1 nanopatterns of regular size (<30 nm in diameter) by using self-assembled diblock copolymers. Next, they have used a statistically enhanced version of the Number and Brightness technique, which can discriminate—with molecular sensitivity—the oligomeric states of diffusive species to quantitatively track the EphB2 receptor oligomerization process in real time. The results indicate that a stimulation using randomly distributed surface-bound ligands was not sufficient to fully induce receptor aggregation. Conversely, when nanopatterned onto our substrates, the ligands effectively induced a strong receptor oligomerization. This presentation of ligands improved the clustering efficiency of conventional ligand delivery systems, as it required a 9-fold lower ligand surface coverage and included faster receptor clustering kinetics compared to traditional cross-linked ligands.
In conclusion, nanostructured diblock copolymers constitute a novel strategy to induce multivalent ligand–receptor interactions leading to a stronger, faster, and more efficient receptor activation, thus providing a useful strategy to precisely tune and potentiate receptor responses. The efficiency of these materials at inducing cell responses can benefit applications such as the design of new bioactive materials and drug-delivery systems
Article:
The PRONANBIOSIS II Network of Excellence ICTS 2017 SAF2017-90810-REDI, granted by the Spanish Minitry of Science to NANBIOSIS, begins its activity planned for two years.
Networks of Excellence favor the development of networks of research groups aimed, in this case, to promote the general coordination of ICTS or Distributed ICTS, as is the case of NANBIOSIS.
This Network will give continuity to the previous PRONANBIOSIS Network, which ended on July 31st. The main purposes of the Network are:
– to consolidate its unified management model,
– to boost its internationalization and strategic positioning
– to promote a complete cascade service for nanomaterials characterization
