NANBIOSIS enables new breakthrough study on Carotid Plaque vulnerability

NANBIOSIS Unit 26 identifies biomarkers of carotid plaque vulnerability, aiding stroke prevention with advanced NMR metabolomics and collaborative innovation.

Valencia, december 2024. NANBIOSIS Unit 26, one of our NMR Biomedical Applications Platforms, has once again demonstrated its essential role in cutting-edge medical research. A recent study, conducted in collaboration with multiple research institutions, identified key biomarkers associated with carotid plaque vulnerability, a critical factor in stroke risk.

A Collaborative Effort in Cardiovascular Research

The study analyzed metabolic differences between symptomatic and asymptomatic carotid plaques, aiming to predict which plaques are at higher risk of rupture. Using advanced nuclear magnetic resonance (NMR) spectroscopy, researchers studied 38 plaque samples and 70 serum samples to identify critical metabolites associated with plaque vulnerability.

The findings revealed that glutamate in plaques and threonine in serum are significant biomarkers for symptomatic cases, providing a foundation for new diagnostic and therapeutic strategies to prevent strokes.

NANBIOSIS Contribution

NANBIOSIS Unit 26, located at the Faculty of Medicine of the University of Valencia (UV) and part of the Centro de Investigación Biomédica en Red (CIBER-BBN), provided the RMN-600MHz required for this research, enabling high-resolution analysis of biological samples.

The Unit’s contribution included processing tissue and serum samples and applying metabolomic profiling techniques to identify and quantify metabolites, yielding robust and reproducible results. The high sensitivity and specificity of these analyses were pivotal to the study’s success.

Implications for Stroke Prevention

Carotid artery stenosis, caused by the accumulation of atherosclerotic plaques, is a leading cause of stroke. However, the risk depends more on plaque vulnerability than the degree of arterial narrowing. The discovery of biomarkers such as glutamate, myo-inositol, threonine, and histamine offers promising pathways for non-invasive diagnostics to assess plaque stability and stroke risk.

Looking Forward

This research highlights the value of metabolomics in understanding cardiovascular diseases and demonstrates NANBIOSIS’s role in fostering collaborative innovation. Future efforts will focus on validating these biomarkers in larger cohorts and exploring their clinical application for early diagnosis and prevention of stroke.

European Partnership Opens a New Era in Rare Disease Research

The European Rare Diseases Research Alliance (ERDERA) kicked off last month, with an estimated budget of 380 million euros and the aim of improving the lives of 30 million rare disease patients in Europe and beyond.

Paris, october 2024. The European Rare Diseases Research Alliance (ERDERA), a new initiative under Horizon Europe, has officially launched with an ambitious mission to improve the lives of 30 million people affected by rare diseases across Europe and beyond.

Backed by a budget of €380 million, ERDERA brings together more than 170 organizations from the public and private sectors, led by the National Institute of Health and Medical Research (INSERM) in France. This collaborative effort aims to advance research on prevention, diagnosis, and treatment for rare diseases, creating a robust infrastructure for innovation and patient support.

ERDERA’s focus is to build on the successes of previous projects, such as the European Joint Programme on Rare Diseases (EJP RD) and the SOLVE-RD project. It strives to create a seamless network of resources and expertise, fostering a globally competitive European research area for rare diseases.

NANBIOSIS participation in ERDERA

CIBER-BBN group led by Ramón Martínez, director of NANBIOSIS and Scientific Director of our Unit 26, together with Juan Antonio Bueren’s group (CIBERER), will participate in a work package aimed at accelerating key technologies in the field of advanced therapies. Specifically, these two CIBER areas will develop new gene and gene-editing therapies, both viral and non-viral, for rare diseases affecting hematopoietic, epidermal, inflammatory, and metabolic disorders. They will employ in vitro and in vivo approaches, as well as lipid nanoparticles for the encapsulation and controlled release of mRNA.

Unit 26 specializes in Nuclear Magnetic Resonance (NMR) technology, providing valuable capabilities for acquiring unique metabolic profiles from a variety of biological samples, including biofluids, cell lines, tissues, and animal models such as mice and rats.

This expertise is crucial in uncovering molecular markers that can help researchers better understand rare diseases, ultimately contributing to the development of more precise diagnostic and therapeutic strategies.

NANBIOSIS Unit 26’s NMR capabilities complement ERDERA’s clinical research network, which aims to accelerate diagnostics and increase clinical trial readiness for rare diseases. The alliance’s comprehensive support services, including a Data Services Hub and an Expertise Services Hub, will benefit from the detailed metabolic profiling provided by Unit 26, further strengthening the infrastructure available to researchers.

Daria Julkowska, ERDERA’s scientific coordinator, highlighted the alliance’s vision of integrating cross-disciplinary expertise under a unified mission: “We have a tripartite mission: One; to bring under one roof a broad range of high-value services, resources and cross-disciplinary expertise to support rare disease research; Two, to boost clinical research by enabling every consenting patient living with a rare disease to be findable and enrolled in a suitable clinical study and finally, to spur innovation and EU competitiveness, through investment but also by aligning regional, national and European research strategies, and fostering collaboration among all stakeholders at a global scale.”

ERDERA’s roadmap, presented during its launch event on 28 October 2024, underscores the importance of collaborations with specialized research infrastructures like NANBIOSIS. Together, these efforts aim to bridge gaps in diagnosis and treatment for rare diseases, transforming the landscape of patient care in Europe.

Ramón Martínez Máñez, Scientific Director of NANBIOSIS U26 obtains an ERC Advanced Grant

Ramón Martínez Máñez, researcher at the Polytechnic University of Valencia (UPV) and scientific director of the Bioengineering, Biomaterials and Nanomedicine area of ​​the CIBER (CIBER-BBN) and NANBIOSIS U26, has obtained an ERC Advanced Grant –the most prestigious grant from the European Research Council– endowed with 2.5 million euros for the development of the EDISON project (Engineered Particles for Chemical Communication).

This project focuses on the field of chemical or molecular communication. Its objective is the study, development and application of nanoparticles that are capable of communicating with each other and whose application would represent a revolution in the field of chemical research.

“Our goal is to advance the understanding of how abiotic micro/nanoparticles can communicate with the others and with living systems. In this context, one way to establish communication at the nanometric level is to mimic how nature communicates, that is, through the use of chemical messengers. If we are able to lay the foundations for communication between micro/nanoparticles and between them and cells, the future potential applications in the biomedical field, and in other fields such as the environment and industrial technology, are almost limitless”, highlights Ramón Martínez Máñez, who is currently deputy director of the Interuniversity Research Institute for Molecular Recognition and Technological Development (IDM) of the Universitat Politècnica València and the Universitat de València.

Unveiling the keys to the prevention and treatment of cancer
In the medical field, for example, these nanoparticles could help reveal the keys to the prevention and treatment of cancer, since they could act as nanotranslators that help connect cancer cells with cells of the immune system, regulating the interactions between them and , in general, to connect cells to each other that would not otherwise communicate. They could also be key in the development of new strategies to eliminate biofilms and resistant microorganisms, being able to detect the presence of chemical species used by bacteria to create the biofilm and inhibiting these signals.

The research proposed by EDISON will be carried out in the IDM, the CIBER-BBN and in the Mixed Units in which Ramón Martínez Máñez participates with the Príncipe Felipe Research Center and with the La Fe Hospital in Valencia.

5 years of work
The project, which began on October 1, will run for 5 years until September 30, 2027. In a first phase, the team from the IDM Institute of the Universitat Politècnica de València will create the basic components to study chemical communication; in the second, EDISON will focus on the development of systems capable of establishing communication between nanoparticles and living systems. Finally, the UPV researchers will work on the development of nanosystems that integrate stimulus-sensitive nanoparticles and electronics to create new hybrid communication structures.

“Every year hundreds of nano/microparticles are described but in practically all cases they are used as independent entities with no connection between them. The connection/communication between particles is the basis for developing more complex cooperative systems with new functionalities”, says Professor Martínez-Máñez, who will dedicate most of his time to the development of the EDISON project with the aim of laying the foundations for this new idea.

Obtaining this prestigious aid will allow the research group to focus on promoting a new form of communication at the nanoscale based on the use of chemical messengers that will facilitate the development of new applications at the nanometric scale beyond what is possible using information and communication technologies on the macroscale that we know today.

Is it possible to communicate microorganisms from different kingdoms? Yes, it is, using “Nanotranslators”

CIBER, March 28 2022

Researchers from the Polytechnic University of Valencia (UPV) and the CIBER-BBN has demonstrated, for the first time, the potential of using “translator” nanoparticles to facilitate communication between different types of cells or microorganisms. His study could have application in multiple fields, especially in the medical field for the prevention and treatment of cancer.

“We have shown that it is possible to communicate microorganisms from different kingdoms using nanoparticles as translators. The nanoparticles process a message produced by the first type of cells (bacteria) and transform it into an understandable message for the second type of cells (yeast) that respond to it. In this way, the information flows from the emitting cells (bacteria) to the nanodevice and from the latter to the receiving cells (yeast), which allows communication between two microorganisms that would not otherwise interact. This is an advance in the design of nanoscale communication systems and opens the door for the development of future applications”, says Ramón Martínez Máñez, researcher at the Institute for Molecular Recognition and Technological Development (IDM) at the UPV and scientific director of the CIBER-BBN and Scientific Director of NANBIOSIS U26,”Biomedical Applications II”.

Among these future applications, the UPV-CIBER-BBN team highlights the possible regulation of the interactions between bacteria and human cells, for example, to prevent infections, kill bacteria or modulate our intestinal microbiome, and for the treatment of diseases such as cancer. “In this case, it would help cells of our immune system to recognize cancer cells more efficiently, regulating the interactions between them,” says Antoni Llopis, a CIBER-BBN researcher at the IDM Institute.

It could also be useful for designing particles that make it possible for plants and fungi to communicate with each other, which could help develop new plant protection strategies. “We could establish communication between plant cells and other microorganisms in their environment in order to prevent pests or use them as a treatment to improve plant performance,” says Ángela Morellá, a researcher at the Institute for Molecular Recognition and Technological Development (IDM) and study co-author.

In any case, the UPV and CIBER-BBN team insist that the results obtained are incipient –“it is a proof of concept”, they emphasize-, although they open a path with great potential for the field of micro/ nanotechnology and synthetic biology.

“Perhaps the biggest challenge will be reading whether the communication between those two kingdoms has been successful or not. In our study, we have used the expression of fluorescent protein by receptor cells, which facilitated the monitoring of the process. The development of future applications will require more advanced methodologies to allow the monitoring of chemical communication processes in complex biological environments”, concludes Ramón Martínez Máñez.

New device for more efficient gluten detection

About 1% of the world’s population suffers from celiac disease, a complex and autoimmune disorder caused by ingestion of gluten and for which there is no treatment beyond its elimination from the diet. In Spain every May 27, the National Celiac Day is commemorated to publicize the disease and give visibility and support to people with celiac disease.

The detection of gluten becomes a key element for celiac patients to control the disease, as well as for the food industry, whose regulation requires declaring its presence in food. In this line, a team of researchers coordinated by the professor of the Polytechnic University of Valencia (UPV) and scientific director of the CIBER of Bioengineering, Biomaterials and Nanomedicine (CIBER-BBN), Ramón Martínez Máñez, are working on the development of intelligent methods for the gluten detection, to avoid the involuntary ingestion of this protein and also collaborate with the regulation and the fight against fraud in the food industry.

Recently published work in Analytica Chimica Acta presents a new system that enables rapid detection of gluten through a simple signaling process. As the authors state, it could be the basis for the development of portable, fast, sensitive and easy-to-use systems for the control of gluten in foods.

“The biosensor is composed of a nanoporous anodic alumina film loaded with a fluorescent dye and covered with an aptamer (DNA or RNA molecule) that specifically recognizes gliadin, which is the soluble protein of gluten” explains M. Carmen Martínez Bisbal, professor from the University of Valencia (UV) and researcher at the CIBER-BBN and the Interuniversity Institute for Research on Molecular Recognition and Technological Development (IDM UPV-UV) and one of the authors of the work. “In the presence of gliadin, the aptamer moves from the surface of the biosensor, resulting in the opening of the pores and the release of the signaling dye” adds Sara Santiago Felipe, researcher at the La Fe Health Research Institute, CIBER-BBN and the IDM UPV-UV and also author of the work.

The new sensor has been validated in real food samples, allowing the detection of gluten through a simple signaling process, with great potential for use in food control. “We have found that it has a detection limit of 100 µg kg-1 of gliadin, good selectivity and a detection time of 60 minutes,” explains Luis Pla, first signatory of the work and researcher at CIBER-BBN and IDM UPV-UV.

“Our results can be the basis for developing portable, simple, fast and sensitive systems for the detection of gluten, which can be easily adjusted through the use of different molecules, offering great potential for allergen testing” concludes the scientific director of the CIBER-BBN and NANBIOSIS Unit 26 Ramón Martínez Máñez.

A new biosensor will help for the early diagnosis of breast cancer

A team of Spanish researchers coordinated by the professor of the Polytechnic University of Valencia (UPV) and scientific director of the CIBER-BBN and NANBIOSIS unit 26, Ramón Martínez Máñez, and the Valencian oncologist, co-coordinator of the Research Group of Biology in Breast Cancer of the INCLIVA Health Research Institute, of the Hospital Clínico de València, Ana Lluch, also belonging to the CIBER de Cáncer (CIBERONC), has developed a prototype of a new biosensor to help detect breast cancer in its phases earlier. The work has been published in ACS Sensors magazine.

According to the latest data collected by the European Cancer Information System (ECIS), in 2020 a total of 34,088 new cases of breast cancer were diagnosed in Spain, this type of tumor being the most frequent among the women in our country.

Currently, mammography is the most widely used standard technique for diagnosis, but it has some limitations, such as radiation exposure, and lower sensitivity and specificity in young women with dense breast tissue. “For this reason, new diagnostic tools are necessary to help in the early detection of breast cancer. Our biosensor follows this line”, explains Ana Lluch.

The development of this prototype biosensor to aid diagnosis is part of the field of what is known as a liquid biopsy, which, through a blood test, helps detect the presence of cancer. In this case, the mesoporous biosensor developed by the UPV and INCLIVA team is simple to use, inexpensive and offers results in a very short time – between 30 and 60 minutes – from a patient plasma sample.

The biosensor is composed of a nanomaterial -a nanoporous alumina- that facilitates the detection in plasma of microRNA miR-99a-5p associated with breast cancer. Until now, this has been done with complex and time-consuming techniques, which means that they cannot be used as a diagnostic tool in the clinical setting.

Ramón Martínez Máñez explains how the alternative diagnostic system in which they work works: the nanopores of the biosensor are loaded with a dye -rhodamine B- and closed with an oligonucleotide. By interacting with the plasma sample, if it does not detect the presence of the microRNA, the pore doors remain closed; instead, in the presence of miR-99a-5p, those gates are opened and the dye is released. “The change in the release of the dye can be correlated with healthy patients or with breast cancer“, summarizes Martínez Máñez.

Researchers from the La Fe Health Research Institute (IIS La Fe) have also participated in the development of this biosensor, where tests have been carried out for the validation of the new biosensors, and the Cancer Network Biomedical Research Center (CIBERONC) .
