NANBIOSIS contributes to innovative protein granules for new biomedical applications

Researchers from NANBIOSIS co-author a new study showcasing an innovative approach to protein-based biomaterials for drug delivery and regenerative medicine.

Barcelona, april 2025. A recent publication in the International Journal of Biological Macromolecules highlights the cutting-edge work of scientists from Unit 1 (Protein Production Platform, PPP) and Unit 18 (Nanotoxicology Unit) of NANBIOSIS, under the leadership of Prof. Antonio Villaverde and Prof. Ramón Mangues, respectively. The study, entitled “Surpassing protein specificity in biomimetics of bacterial amyloids” (DOI: 10.1016/j.ijbiomac.2025.139635), explores the development of artificial protein granules with promising applications in biomedicine.

A Novel Approach to Biomimetic Materials

The research introduces a His-Zn²⁺-based technology to produce artificial protein microgranules that mimic the properties of natural protein depots. By promoting protein–protein interactions through histidine residues and divalent cations like zinc, the team has developed stable yet dynamic microparticles that retain the functional properties of their constituent proteins.

This biomimetic strategy enables the spontaneous formation of hybrid granules by co-aggregating distinct polypeptides. Unlike previous methods, this approach does not require structural similarity among proteins, significantly expanding its potential for versatile biomedical applications.

Cross-Unit expertise and collaboration

The study leverages the protein engineering and production capabilities of NANBIOSIS Unit 1, based at the Institute of Biotechnology and Biomedicine (IBB), Autonomous University of Barcelona (UAB). The infrastructure within this Unit and scientific expertise enabled the design, expression, and purification of the recombinant proteins used in the study.

Meanwhile, NANBIOSIS Unit 18, part of the Institut de Recerca Hospital de la Santa Creu i Sant Pau (Sant Pau), contributed with advanced evaluation and nanotoxicological analysis, ensuring the functional and safe application of these newly developed biomaterials.

Potential applications in Drug Delivery and Regenerative Medicine

The artificial granules described in the paper function as multifunctional protein depots, opening new possibilities in the controlled release of therapeutic proteins and in regenerative medicine. Their hybrid nature allows for simultaneous delivery of multiple functional proteins, enhancing their potential as platforms for personalized medicine and advanced therapies.

Patent and funding

The researchers have filed a patent application to protect the novel His-Zn²⁺ aggregation technology, underlining the potential for translation to industry. The study was supported by multiple funding sources, including national and European research programs.

This research exemplifies the collaborative strength of the NANBIOSIS, where inter-Unit synergies lead to impactful discoveries in nanomedicine and biotechnology. In this case, the Protein Production Platform (Unit 1) and the Nanotoxicology Unit (Unit 18).

Innovative eye drops offer new hope for Retinitis Pigmentosa patients

NANBIOSIS Unit 10 helps develop eye drops with adalimumab for retinitis pigmentosa, showing promising results in preclinical models.

Vitoria, april 2025. A multidisciplinary team of researchers from the Centro de Investigación Biomédica en Red (CIBER), the Centro de Investigación Príncipe Felipe (CIPF), and the University of the Basque Country (UPV/EHU) has developed an innovative eye drop formulation as a potential treatment for retinitis pigmentosa, a hereditary retinal disease that currently lacks effective therapies for most patients. The findings have been published in the prestigious journal Biomedicine & Pharmacotherapy, as reported by CIBER.

The study was led by Regina Rodrigo (CIPF) with significant contributions from Prof. José Luis Pedraz and Dr. Idoia Gallego Garrido, leaders of Unit 10 of NANBIOSIS – Drug Formulation Unit, based at UPV/EHU. The NANBIOSIS platform provided key resources and technological support for the development and physicochemical characterization of the therapeutic formulation.

Therapeutic antibodies

The new approach involves non-invasive eye drops containing adalimumab-loaded nanostructured lipid carriers (NLC–ADA). Adalimumab is a monoclonal antibody that targets TNFα, a pro-inflammatory cytokine involved in retinal inflammation and degeneration. Chronic inflammation has been increasingly recognized as a contributing factor in the progression of retinitis pigmentosa, despite the genetic basis of the disease.

In this preclinical study, researchers assessed the formulation’s physicochemical properties, retinal and corneal safety, and its ability to reduce inflammation and retinal degeneration. The results were highly encouraging: NLC–ADA eye drops improved retinal function, reduced retinal degeneration, and significantly decreased inflammatory markers, all without inducing toxicity.

This strategy offers a non-invasive route of administration and a new avenue for tackling retinitis pigmentosa

Regina Rodrigo

“This strategy offers a non-invasive route of administration and a new avenue for tackling retinitis pigmentosa,” said principal investigator Regina Rodrigo. “It is independent of the genetic defects and could be potentially useful for treating other inflammatory eye diseases.”

International patent application

Given the promising results, the participating institutions – CIPF, UPV/EHU, and CIBER – have jointly applied for an international patent, highlighting the global potential of this therapeutic innovation.

The study was supported by the Instituto de Salud Carlos III, the Generalitat Valenciana, and the ONCE Foundation, with the collaboration of the patient association RETINA Comunidad Valenciana.

Breakthrough Nanotherapy for Colorectal Cancer: Innovative Research Involving NANBIOSIS

Breakthrough nanotherapy targets MSS colorectal cancer, inducing pyroptosis and immune activation. NANBIOSIS Units 1 and Unit 18 played a key role.

Barcelona, march 2024. For this World Colorectal Cancer Day, researchers from Dr. Mangues’ group (CB06/01/1031), in which NANBIOSIS Unit 18 is integrated, have published just last month a groundbreaking study on a novel targeted nanotherapy for colorectal cancer. Conducted in collaboration with three CIBER research groups across two thematic areas (BBN and ER), this research highlights the potential of CXCR4-targeted nanotoxic therapy to combat microsatellite stable (MSS) colorectal cancer, a subtype known for its resistance to immune checkpoint inhibitors and its immunosuppressive tumor environment.

The study, recently published in the International Journal of Nanomedicine, demonstrates the efficacy of CXCR4-targeted cytotoxic nanoparticles in an immunocompetent mouse model of MSS colorectal cancer. This innovative nanomedicine approach selectively eliminates cancer stem cells (CSCs) expressing the CXCR4 receptor by inducing pyroptosis, a type of programmed cell death that triggers a strong immune response. Notably, the treatment leads to the recruitment and activation of eosinophils, key immune cells that contribute to tumor destruction.

The findings emphasize the potential of pyroptosis-inducing nanotherapies to reprogram the tumor microenvironment and enhance innate immune responses against colorectal cancer. The involvement of NANBIOSIS Unit 1 and Unit 18 was instrumental in developing and characterizing this cutting-edge cancer nanotherapy. This contribution involved, respectivelly, the production of a significant range of the proteins used in the study, as well as the entire histological and toxicity studies.

New breakthrough in preventing infections in biomedical implants

A new TPU surface modification with an antimicrobial protein prevents biofilm formation in implants, offering an alternative to antibiotics and metal coatings.

Barcelona, february 2025. Infections associated with medical implants are a serious health issue. A new study presents a chemical modification of thermoplastic polyurethane (TPU) with an antimicrobial protein that reduces the formation of biofilms of multidrug-resistant bacteria, offering an alternative to antibiotics and metal coatings in these devices.

A team of researchers has developed a new strategy to chemically modify TPU, a material widely used in medical devices, to endow it with antibacterial properties and prevent infections associated with biomedical implants. This innovation could represent a significant advancement in the safety and durability of medical implants. The study is part of a project funded by La Marató de TV3.

The study, led by Imma Ratera, researcher at the Nanomol-Bio group at ICMAB-CSIC and CIBER-BBN, and recently published in ACS Applied Bio Materials, describes how the chemical modification of the TPU surface and the self-assembled monolayer strategy are key to enabling the anchoring of the recombinant human α-defensin 5 (HD5) protein.

This specific surface functionalization promotes interaction with the antimicrobial protein, effectively inhibiting bacterial biofilm formation. The surface modification was achieved through a three-step process: activation of TPU with hexamethylene diisocyanate (HDI), interfacial reaction with polyethylene glycol (PEG) derivatives, and finally, a simple click reaction between the PEG-maleimide terminated assembled monolayer and the HD5 protein.

The material has been characterized using advanced surface science techniques, confirming its antibacterial efficacy. The results show a significant reduction in the formation of biofilms of resistant gram-positive and gram-negative bacteria, such as Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus (MRSA), and methicillin-resistant Staphylococcus epidermidis (MRSE).

This technology offers a promising alternative to antibiotics and metals like silver, addressing the issue of antimicrobial resistance in implantable medical devices. “This breakthrough could represent a paradigm shift in preventing infections in medical implants, reducing complications, and improving patient safety,” says Ratera.

This discovery opens new avenues for the development of antimicrobial surfaces in medical devices, with great potential to improve clinical outcomes and reduce healthcare costs associated with hospital-acquired infections.

The study was conducted by researchers from the Institute of Materials Science of Barcelona (ICMAB-CSIC) and the Biomedical Research Networking Center – Bioengineering, Biomaterials, and Nanomedicine (CIBER-BBN), in collaboration with the Institute of Agrifood Research and Technology (IRTA), the Hospital Clínic-Institute of Biomedical Research August Pi i Sunyer (IDIBAPS) with the Biomedical Research Networking Center on Infectious Diseases (CIBER-INFEC), and the Hospital Universitari Parc Taulí.

The luminescence characterization of the modified TPU surfaces was carried out at Unit 6 of the ICTS Nanbiosis, specializing in the preparation and characterization of nanostructured biomaterials.

Advancing new treatments for Retinitis Pigmentosa within NANBIOSIS

NANBIOSIS Unit 10 develops lipid-based nanoparticles for gene and drug delivery, aiming for cost-effective, non-invasive treatments for retinitis pigmentosa.

Vitoria, february 2025. Retinitis pigmentosa (RP) is a congenital rare disease that leads to progressive and irreversible vision loss. Both genetic mutations and inflammation contribute significantly to the progression of the disease. Researchers from the Drug Formulation Unit (U10) of NANBIOSIS, based at the University of the Basque Country (UPV/EHU), are pioneering innovative strategies to combat this condition. Their work focuses on developing lipid-based nanovehicles for gene and drug delivery, aiming for cost-effective and non-invasive treatments for RP patients.

Gene Therapy: A Novel Approach to Address Retinal Mutations

Unit 10 is engineering lipid-based nanoparticles to deliver genetic material to the retina effectively. In collaboration with the research group of Eduardo Fernández Jover, at Universidad Miguel Hernández (CIBER-BBN), they are testing these nanoparticles by delivering plasmids encoding the green fluorescent protein (GFP) to retinal layers. This strategy allows researchers to assess gene delivery efficiency at different retinal depths. Since over 200 gene mutations have been identified at the outer retinal layer that contribute to severe retinal diseases, reaching these layers is crucial for therapeutic success. The next phase of research involves incorporating therapeutic genes such as RPE65, one of the most frequently mutated genes in RP, to evaluate their potential clinical benefits.

Anti-Inflammatory Drug Delivery: Enhancing Retinal Protection

Alongside gene therapy, the team is exploring the use of lipid-based nanoparticles to deliver anti-inflammatory agents. In collaboration with the research group of Regina Rodrigo, at Centro de Investigación Príncipe Felipe (CIBER-ER), they aim to encapsulate therapeutic compounds in these nanocarriers, protecting them from degradation and enabling controlled release into the retina. Notably, they have achieved successful non-invasive administration via eye drops, culminating in the application for a PCT patent (PCT/EP2024/052232). The next steps involve expanding this technology to treat additional retinal inflammatory conditions and investigating the encapsulation of other anti-inflammatory compounds.

“We aim to face retinitis pigmentosa by a multidisciplinary strategy using lipid nanoparticles to target the retina as potential cost-effective and non-invasive treatments for patients.”

Idoia Gallego Garrido, Scientific Coordinator of Unit 10.

A Multidisciplinary and Translational Strategy

The combined gene and drug delivery approaches spearheaded by Unit 10 offer a promising outlook for RP patients. By leveraging lipid nanoparticles, the researchers aim to develop cost-effective and non-invasive therapeutic solutions.

This research aligns with the commitment of NANBIOSIS to bridging scientific innovation with translational medicine, fostering collaborations between academia and industry to accelerate the development of advanced therapeutic solutions.

New Dendritic Platinum Nanocatalysts for Selective Activation of Anticancer Drugs

PEGylated dendritic platinum nanoparticles enable targeted drug activation, reducing tumors in vivo. Developed with NANBIOSIS Unit 9, they enhance cancer therapy.

Zaragoza, february 2025. A recent study published in Angewandte Chemie International Edition (see reference at the end of the article) introduces a novel approach in cancer treatment through the development of PEGylated dendritic platinum nanoparticles. These nanoparticles exhibit high biocompatibility and selectively activate anticancer drugs within cancer cells.

The study was co-led by members of the Nanostructured Films and Particles (NFP) group, Dr. Jose I. Garcia-Peiro, Dr. Jose L. Hueso and Prof. Jesus Santamaria (Group Leader) that belong to CIBER-BBN, the Institute of Nanoscience and Materials of Aragon (INMA-CSIC), the Department of Chemical and Environmental Engineering at the University of Zaragoza and the Instituto de Investigacion Sanitaria de Aragon (IISA).

Dr. M. Carmen Ortega-Liebana, Dr. Catherine Adam as two of the main leading contributors and Dr. Alvaro Lorente-Macias, Dr. Jana Travnickova and Dr. Elisabeth Patton were also participants from Unciti´s group in Edinburg. In addition, Paula Guerrero and Prof. Jose Manuel Garcia-Aznar from the Aragon Institute of Engineering Research (I3A-University of Zaragoza) validated the results with 3D model culture studies.

Interestingly, the study demonstrates the viability and efficacy of the combination of the prodrug pro-SN38 with dendritic platinum heterogeneous nanocatalysts in two-dimensional (2D), three-dimensional (3D) cell cultures, as well as in vivo zebrafish models. This study also paves the way to novel platinum formulations beyond classical platinum-based chemotherapeutics with higher toxicity and higher deactivation in tumor environments.
