The fight against rare respiratory diseases: New hope in detection and treatment

Researchers from IQAC-CSIC advance towards faster detection and treatment of cystic fibrosis and rare respiratory diseases, improving patient outcomes.

28 February 2024, IQAC-CSIC (Barcelona)

Cystic Fibrosis (CF) is a progressive autosomal recessive disease. It is caused by a mutation in the gene encoding the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein, disrupting its exocrine activity. While CF affects various organs, its impact on the lungs is particularly severe. This disease leads to the accumulation of thick, sticky mucus, obstructing airways and trapping bacteria, resulting in significant infections and extensive lung damage. Consequently, individuals with CF are highly susceptible to respiratory tract infections. In this regard, Pseudomonas aeruginosa and Staphylococcus aureus are among the most prevalent pathogens.

Early detection of P. aeruginosa and S. aureus in CF patients is crucial to eradicate these pathogens before the development of chronic colonization. Moreover, even after the chronic colonization occurs, proper control of the bacterial burden is necessary to minimize progressive lung deterioration. Currently, the gold standard for detecting these bacteria involves conventional bacterial culture methods. However, as in any infectious process, time is of the essence, and these techniques typically take 2 to 3 days to be confirmed. Hence, there is an urgent need to develop faster, more sensitive, and specific diagnostic methods.

In this context, the Nanobiotechnology for Diagnostics (Nb4D) group at the IQAC-CSIC, in which the Unit 2 of NANBIOSIS (CAbS) is integrated, focuses much of its research on bacterial communication systems, specifically Quorum Sensing (QS).

Quorum Sensing is a fascinating mechanism that allows bacteria to react to the presence of other bacteria. In other words, QS regulates bacterial gene expression in response to fluctuations in microbial population density. QS-sensitive bacteria produce and release signaling molecules called autoinducers (AIs). Just the detection of a minimum concentration of AIs triggers radical changes in gene expression, activating processes such as biofilm formation or virulence.

The QS system is well-characterized for both P. aeruginosa and S. aureus. This makes the detection of these AIs, or even QS-regulated virulence factors (VFs) (such as the aforementioned biofilm formation), a promising approach for bacterial identification. As a consequence, by knowing how AIs and VFs work, doctors can predict how an infection may progress. Much like a bacterial molecular fingerprint.

Thanks to their solid know-how, the Nb4D group has developed specific antibodies against AIs and VFs of both bacterial species. With that under their belt, this group has designed ELISA assays capable of detecting these molecules. Then, using this popular technique, they managed to run detection tests in approximately 2 hours, both in bacterial isolates and sputum human samples.

Additionally, our researchers are evaluating these antibodies as therapeutic agents using cell cultures, using their antibodies to block dangerous VFs and AIs. These studies are yielding promising results in mitigating the cytotoxic effects caused by the aforementioned VFs and AIs.

Detecting Alpha-1-antitrypsin protein

In addressing rare diseases related to the respiratory system, the Nb4D group is also involved in developing a device for detecting Alpha-1-antitrypsin protein. The genetic deficiency of this protein causes damage to the lungs and liver, affecting 1 in every 2500 individuals in Europe. Rapid and highly sensitive detection of Alpha-1-antitrypsin levels should enable immediate treatment initiation, thereby preventing potential complications.

This research line represents an example of clinical cooperation. It involves collaboration with clinical personnel from Hospital del Mar, Hospital Germans Trias i Pujol (Barcelona), and Hospital Son Espases (Mallorca). In addition, the interest has peaked to the point of attracting funding such as State ‘Plan Estatal de I+D+I’, as well as a grant from the ‘Fundació La Marató’ of TV3, among other sources.

Through innovative diagnostic and therapeutic approaches, the Nb4D group is dedicated to improving outcomes for individuals affected by rare respiratory diseases. This involves their work in cystic fibrosis among other conditions, pushing forward the understanding and management of these challenging diseases.

The importance of bacterial Quorum Sensing (QS) research recognised in the Princesa of Asturias Awards

Today, Bonnie Bassler, Jeffrey Gordon, and Peter Greenberg are receiving the Princess of Asturias Award for their contribution to the knowledge of the role of the human microbiome and the bacteria Quorum Sensing.

Targeting Quorum Sensing allows understanding of bacteria behaviour and pathogenesis, but also developing new therapeutic and diagnostic strategies for infectious diseases.

Bonnie Bassler has shown how small chemical signals are involved in such a communication process.

Peter Greenberg was one of the first scientists who assigned the term Quorum Sensing (QS) to such a sophisticated system used by bacteria to communicate and synchronize behavior. He was involved on the discovery of the QS signalling pathways of important pathogens such as Pseudomonas aeruginosa and their implication on virulence and biofilm formation, key for the establishment of chronic and antibiotic-resistant infections

Jeffrey Gordon is a pioneer of microbiome research. These billions of bacteria living in our bodies have an extraordinary effect on our health, determining metabolic or even neurological disorders. His discoveries are tackling global issues such as childhood malnutrition.

The winners explained at the press conference the importance of this award:

“I couldn’t imagine that was going to be awarded the “Premio Princesa de Asturias” when I see those who have achieved it… they are icons, they are my idols in all kinds of fields!”, said Bonnie Bassler. Peter Greenberg explained that it is not only a recognition of the work done over many years in their research group but also of the work done by all the scientists in microbiology “This honor that has been granted to us is a recognition of how important microbiology and science in general is”.

From NANBIOSIS ICTS we want to congratulate the winners and thank the Princess of Asturias Foundation for the recognition of a piece of research which is of specific interest in our Unit 2-CAbS, research group Nb4D – from CIBER-BBN and IQAC-CSIC, led by M.

New method for the detection of RNA viruses such as SARS-CoV-2

Several CIBER-BBN groups at the University of Barcelona, the Institute for Advanced Chemistry of Catalonia (IQAC-CSIC), the Institute of Microelectronics of Barcelona (IMB-CNM-CSIC) and the Institute of Nanoscience and Materials of Aragon (INMA) —a joint institute of the CSIC and the University of Zaragoza (UNIZAR)— have developed a new method for detecting RNA viruses based on the technology of using probes that form triplex structures. This innovative methodology opens up new options to detect viruses such as SARS-CoV-2, the influenza A (H1N1) virus or the respiratory syncytial virus (RSV), a pathogen that affects newborns and requires differential diagnostic care.

This interdisciplinary work, published in the International Journal of Molecular Sciences, is led by Carlos J. Ciudad and Verónica Noé, from the Faculty of Pharmacy and Food Sciences and the Institute of Nanoscience and Nanotechnology (IN2UB) of the University of Barcelona ; Ramón Eritja, Anna Aviñó, Lluïsa Vilaplana and M.Pilar Marco, from IQAC-CSIC and CIBER-BBN; Manuel Gutiérrez, Antoni Baldi and César Fernández, from the IMB-CNM-CSIC, and Valeria Grazu and Jesús Martínez, CSIC researchers at the Institute of Nanoscience and Materials and Aragon INMA (CSIC-UNIZAR) and CIBER-BBN.

The research has counted with the expertise of two NANBIOSIS Units from CIBER-BBN and IQAC-CSIC; NANBIOSIS U2 Customized Antibody Service (CAbS), led by Pilar Marco and Nuria Pascual, and U29 Oligonucleotide Synthesis Platform (OSP), led by Ramón Eritja and Anna Avinó.

This research work was carried out in the context of the PoC4CoV project, led by M. Pilar Marco and César Fernández and financed through the Interdisciplinary Thematic Platform of Global Health of the CSIC. Subsequently, the research has continued as part of a project financed by La Marató de TV3 in 2020 to fight against COVID-19 in which experts from the Faculty of Chemistry of the UB also participate.

Polypurine tweezers to capture viral RNA
The new methodology is based on the ability of polypurine tweezers (PPRHs) —designed by the UB cancer therapy group— to capture viral RNA and form a high affinity triplex. When this hybrid structure is connected to a molecular probe and is brought into contact with the affected patient’s sample, a viral agent detection signal is obtained. The method now presented in the scientific publication has been called the Triplex Enhanced Nucleic Acid Detection Assay (TENADA).

“PPRHs are unmodified single-stranded DNA hairpins that are made up of two mirror domains of antiparallel polypurines. These domains, connected to each other by a thymidine loop, are linked by intramolecular reverse Hoogsteen bonds. Molecular tweezers can specifically bind to polypyrimidine sequences in single-stranded (ssDNA), double-stranded (dsDNA) or RNA viruses through Watson-Crick bonds, thus forming an antiparallel triplex”, details Professor Carlos J. Ciudad, from the Department of Biochemistry and Physiology of the UB.

An effective and faster methodology than the PCR test
Among the advantages that it presents in the detection of viral RNA, it should be noted that the PPRHs methodology can be applied without the intervention of reverse transcriptase —the enzyme that converts RNA into DNA— or the thermocycler (the device that amplifies the material samples). DNA with polymerase chain reaction or PCR). In addition, it has a sensitivity and specificity equivalent to that of the PCR test and can provide results in less than an hour.

In the framework of the work, the team used the hybridization sandwich format in various biosensing devices. This approach uses two oligonucleotides: a triplex-forming PPRH hairpin to serve as the capture probe, and a labeled duplex-forming DNA oligonucleotide to serve as the detection probe.

“The triplex-forming PPRH hairpins were designed to bind to SARS-CoV-2 polypyrimidine sequences, while the detection probes were designed to complement a region near the polypyrimidine target site. Thus, the presence of SARS-CoV-2 RNA is detected by the formation of the ternary complex on the surface of the biosensor”, details Professor Verónica Noé (UB-IN2UB).

This methodology has been implemented in a compact electrochemical device that integrates an electrochemical cell with two electrodes on a chip —manufactured in the Micro and Nanofabrication White Room of the IMB-CNM-CSIC— and a paper fluidic component, and in a Lateral thermal flow implemented in nitrocellulose and using plasmonic nanoparticles and thermal paper that has been developed at the INMA (CSIC-UNIZAR).

TENADA: applications in biomedical research
PPRHs are described in the scientific literature as gene silencing tools for various genes mainly involved in cancer. In addition, they have also been incorporated as probes in biosensors for the detection of small RNA molecules (micro-RNA) to determine the state of DNA methylation and for the diagnosis of pneumonia caused by the fungus Pneumocystis jirovecii.

Now, the new TENADA methodology proves to be effective not only in the detection of viral particles. The high affinity of PPRHs for viral RNA is a property that can be applied to inhibit the virus replication process. For this reason, the antiviral properties of CC1PPRH and CC2PPRH polypurine clamps in cells of the VeroE6 lineage infected with SARS-CoV-2 virions are now also being studied.

In parallel, the work of the different groups involved has also been the basis of a technology that was patented and licensed in July 2022 through the participation of the UB Patent Center, the CSIC and the CIBER-BBN. In turn, this patent has been licensed non-exclusively to the Spanish company Nanoinmunotech through the management of the Bosch i Gimpera Foundation (FBG-UB) in the technology protection process and the company’s license agreement. .

Happy Day of Chemistry! The role of Chemistry in a sustainable research in health

Today, November 15 is a day of celebration for us, the Day of the Chemistry in Spain!

Chemistry is the science that studies matter, how it is composed, its properties and how its structures are transformed and, as matter is everything, including living beings and ourselves, we can say that chemistry is omnipresent and transversal in all areas surrounding us. Chemistry is everywhere, we ourselves are chemistry and our health and our life is chemistry.

“Everything around us is chemistry in the environment, foods, what we use and what we touch every day. Our own body is a sophisticated complex factory with an infinite number of chemical processes taking place on a perfect and synchronized manner”- points Pilar Marco, Scientific Director of NANBIOSIS U2 Custom Antibody Service (CAbS) from CIBER-BBN at IQAC-CSIC.

The crucial role of chemistry in everyday life is also evidence in the development of current technology and the economy. According the VCI Prognos Study, the Global growth forecast for Industrial Sectors, places the chemical industry in the fist position. As far as national picture, the INE Statistics on R+D Activities 2020 -last publish report-, chemical and pharmaceutical industry employs the 22,2 % of research staff recruited and the investment and expenditure on the chemical and pharmaceutical industry represents the 23,6% R+D and Innovation -above the motor vehicles industry.

Thanks to chemical and pharmaceutical research,

medicines, vaccines and health products have made great strides in fighting diseases and improving quality of life. Thanks to chemical and pharmaceutical medicine research, in few years, it will be possible, for example, to count on smart implants delivering personalised drugs only where cancer or infections are detected or biosensors circulating in our body to find diseases only one week after infection.

At the Institute of Advanced Chemistry of Catalonia, four NANBIOSIS units of CIBER-BBN use chemistry to deliver new therapeutic and diagnostic approaches that improve the quality of life of the society.

One of the research lines of the Nb4D group-U2 CabS at IQAC-CSIC (led by Pilar Marco and Nuria Pascual) focuses on the chemical signals that bacteria emit to communicate with each other and thus develop virulence mechanisms. Their knowledge will allow the development of new therapeutic and diagnostic strategies to mitigate the serious problem of antimicrobial resistance.

NANBIOSIS U3 Synthesis of Peptides Unit– MS4N group, led by Miriam Royo, explores the use of diverse types of chemical multivalent platforms (oligomers, dendrimers, polymers, micelles and lipid nanovesicles) for the development of drug delivery systems for cancer treatment, protein delivery systems for the treatment of lysosomal diseases and macromolecular compounds that have intrinsically therapeutic properties with application to central nervous system diseases.

Chemistry plays an essential role in helping society achieve Sustainable Development Goals (SDGs)

In 2015 the United Nations created a universal call to action to end poverty, protect the planet, and ensure that all people enjoy peace and prosperity by 2030. This framework, comprising 17 aspirational goals known as the Sustainable Development Goals (SDGs)

Chemistry is key to achieve the SDG 3: Good Health & Well-Being with the development of new technologies that will provide a deeper understaunding of human health, making posible better, cheeper and faster medical diagnosis and treatmens.

In this sense, Carlos Rodriguez Abreu, Scientific Director of NANBIOSIS Unit for the characterization of nanostructured liquids (U12) explains: “The goals of sustainable development are producing a shift towards surfactants not based on petroleum derivatives, but derived from other raw materials that are more biocompatible and that allow a circular economy that is less aggressive with the environment. Quality control is necessary with regard to the properties of the products that contain surfactants, such as the droplet size in emulsions, the particle size in suspensions, their colloidal stability over time, among others. Additionally, products must be precisely formulated to optimize the use of raw materials and obtain the desired properties. In this context, the NANBIOSIS U12, acredited with ISO 9001:2015 by AENOR, offers a wide range of advanced analysis techniques for the determination of different colloidal properties such as droplet size and particle size, colloidal stability, viscosity, surface tension, pore size distribution, and determination of phase behavior and structure for the tailor-made formulation of surfactant and colloid systems for pharmaceutical and biomedical applications.

The Nucleic Acid Chemistry group at IQAC-CSIC – NANBIOSIS U29 Oligonucleotide Synthesis Platform (OSP) is developing new compounds based in DNA and RNA to detect and treat diseases participating in several projects with several research and industrial partners such as La Marato de TV3 (Covid), Oligofastx, Caminan2, Osteoatx. These new drugs use the natural mechanisms for gene regulation to treat undruggable diseases such Muscular dystrophy and others. Importantly special attention is made to design novel synthetic protocols to produce less organic waste what contributes to the sustainable development.

We wish to all the family of chemistry professionals new projects and inspiration to achive humans Good Health & Well-Being and keep the world moving!

And Happy Chemistry Day, too, for all the chemistry enthusiasts!
