NANBIOSIS in the new poster of ICTS map published by Spanish Goverment.

ICTS underpins the Spanish reputation for research excellence.

In the picture: the new poster of the ICTS map in which NANBIOSIS facilities have been highlighed

The term Unique Scientific and Technical Infrastructure (ICTS) refers to facilities, resources, or services for the development of top-quality cutting-edge research, as well as the communication, exchange, and preservation of knowledge, the transfer of technology, and promotion of innovation. They are unique or exceptional in their fields, with a high cost of investment, maintenance, and operation, and are of a strategic importance that justifies their availability to all actors in the field of R&D&I. The ICTS share three fundamental characteristics; they are infrastructures with public ownership, unique and open to competitive access.

ICTS offer an opening capacity percentage of their essential services under ‘Competitive Open Access’ for the use by national and international public and private sector researchers, with the support of technical and administrative personnel of the ICTS. Infrastructures access is ruled by a public “Access Protocol” that describes the procedure and criteria for access to the infrastructure. The main features of ‘Competitive Open Access’ are that R + D + i quality of activities developed at the infrastructure should be proven and that requests for access should be prioritized on the basis of objective criteria.

The dissemination of ICTS and their capabilities is essential to provide Spanish and international researchers with access to a large base of quality services and facilities, a basic requirement for the development of excellent science.

The new posster pushised by the General Subdirectorate of Large
Scientific-Technical Facilities of the of the Sapanish Ministry of Science and Research Innovation helps to disseminate and understand the map of ICTS wich are located throughout the country

NANBIOSIS, is one of the five ICTS in the field of Health Sciences and Biotecnology

Antitumoral nanoparticles with multiple activities, a close reality.

Conventional chemotherapeutics used to fight cancer promote off-target damage in cells and organs that are not affected by the disease. This major drawback may be overcome with the development of tumor-targeted therapies, in which the antitumoral drugs are selectively delivered to tumoral cells using the efficient recognition between a receptor overexpressed in these cells and its ligand, without promoting off-side effects in the rest of the body.

The group of Nanobiotechnology (NBT) from the Institut de Biotecnologia i Biomedicina (IBB-UAB), led by Prof. Antonio Villaverde, develops a new concept of pharmaceuticals based on protein nanoparticles, in close collaboration with the group of Oncogenesis and Antitumor Drugs (GOA) from the Institut d’Investigació Biomèdica Sant Pau (IIB-Sant Pau) and the group of Nucleic Acids Chemistry from the Institute for Advanced Chemistry of Catalonia (IQAC-CSIC), respectively lead by Prof. Ramon Mangues and Prof. Ramon Eritja. This research is conducted in the frame of the Director plan of CIBER-BBN, an excellence center from the Instituto de Salud Carlos III, to which all the groups belong, being assisted by three Nanbiosis ICTS units (U1, Protein Production Platform; U18, Nanotoxicology Unit; U29, Oligonucleotide Synthesis Platform).

The generated pharmaceuticals are selective for metastatic stem cells, responsible of cancer propagation, recurrence and bad prognosis, that overexpress in their surface the CXCR4 receptor, present in 23 distinct human neoplasias. Using a precise protein engineering, we generate multi-functional protein nanoparticles that remain in the bloodstream for long times and selectively enter and destroy metastatic stem cells, thus contributing to stop cancer progression. In the last years, we have employed two main strategies in the development of antitumoral protein nanoparticles. On one side, current chemotherapeutics already used in clinics in non-targeted approaches, such as Floxuridine or Monomethyl Auristatin E, are chemically linked to targeted protein nanoparticles that serve as drug delivery systems and comprise an inert scaffold, a polyhistidine tag and a targeting peptide that directs their effect to the CXCR4-tumor. On the other side, the inert scaffold of our protein nanoparticles is replaced by toxins, venoms or other death-inducer proteins that confer the protein nanoparticle an intrinsic antitumoral activity, without the need of delivering chemical drugs. Both strategies are protected by intellectual property rights.

Recently, we have explored the possibility of combining both strategies to generate intrinsically toxic nanoparticles loaded with conventional chemotherapeutics in a single pharmacological entity. This way, we seek to potentiate their antitumoral effect and face the appearance of resistances in the tumor. In this initial step, the concept proposed has been demonstrated as fully feasible, as stable nanoparticles that contain both the toxin and the loaded chemotherapeutics were generated. Although these novel nanomaterials do not improve toxic antitumoral activities in CXCR4+ tumor cell lines, this research has been crucial to identify the main bottleneck of the technology, that is achieving a precise control of the drug-binding site in order to maintain the antitumoral activity of targeted toxins, which must act at the same time as active principle and as anchoring site for chemical drugs.

This novel platform recruits in a single pharmacological entity different therapeutic actions and may open a broad investigation field in the design of antitumoral drugs. The current results of this project have been published in the scientific journal Acta Biomaterialia and presented in the international conference NALS2022 by Eric Voltà-Durán.

Induced pluripotent stem cells in disease modelling and experimental therapies: cardiovascular perspective

On the 20th of May, we will be receiving an international visit at the  Unversity of Zaragoza from Pr. Józef Dulak from Jagiellonian University, Kraków, Poland. The title of the talk will be “Induced pluripotent stem cells in disease modelling and experimental therapies: cardiovascular perspective“.

The invited lecture is programed within the framework of the European CISTEM project, in wich the University of Zaragoza participates through CIBER-BBN group TME lab – NANBIOSIS U13 Tissue & Scaffold Characterization Unit.

The event will take place at 12:00 in the I3A SEMINAR (2nd floor) of Campus Rio Ebro, of University of Zaragoza

Induced pluripotent stem cells (iPSC) are generated by genetic reprogramming of somatic cells and thanks to the ability to differentiate into almost all cells types of the organism they offer the enormous possibilities for investigating disease mechanisms, drug sensitivity and safety and for experimental regenerative approaches.  iPSC thus became the indispensable tools of current medial biotechnology and received additional input thanks to the development of the CRISPR/Cas9 gene editing.

In this lecture PR. Józef Dulak will review his research in which iPSC and CRISPR/Cas9 gene editing is applyed for investigating the iPSC-differentiation to cardiomyocytes, endothelial cells and other cell types linked with the disease affecting vascular system, heart and the skeletal muscles. The special attention will be on discussing the potential of iPSC for diabetes and Duchenne muscular dystrophy disease modelling.

Application of iPSC-derived cardiomyocytes offer the chance for effective cell therapy of heart failure and this will be addressed in regard to recently published studies.

OPEN SUBMISSION FOR JOURNAL SPECIAL ISSUE ON OLIGONUCLEOTIDE BASED THERAPIES

Dr. Ramon Eritja, Scientific Director of NANBIOSIS unit 29 of Oligonucleotide Synthesis Platform (OSP) and Dr. Santiago Grijalvo researcher at NANBIOSIS unit 12 of Nanostructured liquid characterization, from CIBER-BBN and IQAC-CSIC, together with Dr. Andreia F. Jorge, from Coimbra Chemistry Centre (CQC), acting as guest editors of journal Pharmaceutics, of MDPI Publisher, welcome authors to submit their articles on special issues on Recent Trends in Oligonucleotide Based Therapies.

In the past few decades, significant efforts have been made towards the clinical application of oligonucleotides. However, the potential of the therapeutic applications of RNA-based strategies have recently been spotlighted after the first approval of mRNA vaccines in response to COVID-19 pandemic. These molecules have the power to tackle targets that are usually considered to be “undruggable” by blocking the translation or transcription of a specific gene by stimulating the degradation of a particular messenger RNA.

This Special Issue aims to collect reviews, original research articles, and short communications covering innovative strategies in the design, synthesis, and characterization of therapeutic oligonucleotides as well as advances in their delivery based on nanotechnologies. Research concerning the study of sequence-specific protein–DNA/RNA interactions will be also considered.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form.

For all the informations and instructions about the Special Issue, please visit this MDPI page

Deadline for submissions: 31 December 2022
