NANBIOSIS contributes to translational project developing protein-based therapy for brain hemorrhage recovery

NANBIOSIS supports IdiPAZ project to develop protein-based therapy from extracellular vesicles to improve recovery after brain hemorrhage.

Barcelona, September, 2025 — The Protein Production Platform (PPP, NANBIOSIS Unit 1) has joined an innovative translational research project led by the Neurology and Cerebrovascular Diseases Group at the Health Research Institute of Hospital Universitario La Paz (IdiPAZ).

The project, funded by the Instituto de Salud Carlos III (ISCIII) under grant PI23/00436, focuses on the development of a new protein-based treatment to improve recovery after brain hemorrhage. The strategy involves the administration of encapsulated therapeutic proteins, representing a novel approach to enhance functional outcomes in patients. The study is coordinated by Dr. María Alonso de Leciñana and Dr. María Gutiérrez.

Proteins derived from extracellular vesicles

The therapeutic concept stems from a promising clinical observation. Proteins of interest were identified by analyzing extracellular vesicles in the peripheral blood of patients with spontaneous favorable recovery after brain hemorrhage. Previous research by the IdiPAZ group demonstrated that these vesicles carry higher levels of proteins involved in cellular repair and regeneration, particularly in patients with better neurological outcomes.

Role of NANBIOSIS Unit 1 in protein production

The selected proteins are currently being synthesized at NANBIOSIS Unit 1, and the optimization of their purification in soluble and biologically active form is in progress. Unit 1 is specialized in protein production and purification services for biomedical research. These proteins will then be encapsulated using advanced formulations developed by Diversa Technologies, a Spanish biotech spin-off created from the Health Research Institute of Santiago de Compostela (IDIS).

From toxins to allies: A new tool to cross cellular barriers

Researchers use a bacterial toxin domain to boost drug delivery across skin barriers, opening new paths for non-invasive protein-based therapies.

Barcelona, april 2025. Researchers from NANBIOSIS Units at UAB and IR Sant Pau develop innovative strategy for transdermal protein drug delivery using recombinant proteins.

In a major advance in drug delivery research, scientists from NANBIOSIS Unit 1 and Unit 18 at the Universitat Autònoma de Barcelona (UAB) and the Institut de Recerca Sant Pau, affiliated with the CIBER-BBN network, have demonstrated a novel method to increase the permeability of epithelial tissues. By harnessing the non-toxic functional domain of a bacterial toxin, the team has opened new pathways for transdermal and transmucosal delivery of protein-based therapeutics.

The study, recently published in the prestigious journal Molecular Pharmaceutics (American Chemical Society, ACS), was led by Dr. Antonio Villaverde and Dr. Esther Vázquez, with significant contributions from Eric Volta-Durán and other members of NANBIOSIS, such as Ramón Mangues and Isolda Casanova. The research is part of the project PID2020-116174RB-I00, funded by the Agencia Estatal de Investigación (AEI).

Our findings pave the way for the use of recombinant proteins as vehicles in non-invasive transdermal therapies

—Dr. Antonio Villaverde

“Our findings pave the way for the use of recombinant proteins as vehicles in non-invasive transdermal therapies,” explains Dr. Villaverde. “The use of functional domains like c-CPE, derived from natural proteins, shows the power of biotechnology to transform nature’s molecular tools into biomedical innovations.”

c-CPE: From bacterial toxin to drug delivery enabler

The team focused on c-CPE, a functional domain of the Clostridium perfringens enterotoxin, known for its ability to bind tight junctions between epithelial cells. Through advanced protein engineering and characterization techniques, researchers developed highly pure and stable recombinant proteins containing this domain.

(…) c-CPE enables the passage of other proteins across epithelial monolayers, without inducing toxicity.

—Eric Volta-Durán

“Thanks to our expertise in recombinant protein design and purification, we created multifunctional proteins that efficiently bind to cell-cell contact regions,” says Eric Volta-Durán. “Using confocal microscopy, we confirmed that c-CPE enables the passage of other proteins across epithelial monolayers, without inducing toxicity.”

Interestingly, the study found that while c-CPE-fused proteins strongly attach to tight junctions and do not themselves cross the barrier, they act as trans-permeabilization agents—allowing other, non-modified proteins to pass through epithelial layers.

This paradoxical “trans-mediated, cis-inhibited” behavior of c-CPE suggests a promising mechanism for enhancing drug bioavailability in non-invasive therapeutic strategies, including topical applications, wound healing, and transmucosal treatments.

Cutting-edge nanobiotechnology for precision medicine

This breakthrough is a prime example of how NANBIOSIS supports the development of frontier biotechnological tools. The research benefited from the advanced capabilities of NANBIOSIS Unit 1 and Unit 18, located at UAB and IR Sant Pau respectivelly, including facilities for protein production, purification, characterization, and nanomedicine testing.

By converting a natural bacterial toxin into a helpful ally, the study highlights the transformative potential of biotechnology and nanomedicine for improving therapeutic delivery across complex biological barriers.

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).

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.

Knowdlege growth: A chart-guide for cloning, production, purification, and characterization of recombinant proteins from prokaryotic systems

The Nanobiotechnology Group and NANBIOSIS PPP have created a poster-guide for recombinant protein cloning, production, and purification in prokaryotic systems.

Barcelona, october 2024. The Nanobiotechnology Group, led by Prof. Villaverde, in collaboration with the NANBIOSIS Unit 1, Protein Production Platform (PPP), directed by Dr. Ferrer-Miralles, has created an in-depth guide in the form of a poster that compiles key strategies for cloning, production, purification, and characterization of recombinant proteins expressed in prokaryotic systems.

Drawing from their vast experience in the field, they have meticulously outlined techniques and best practices to address common challenges and optimize every stage of the process. The poster covers various aspects of recombinant protein workflow, including selecting the right expression vectors, optimizing culture conditions, purification strategies, and the essential steps for characterizing the final purified protein.

The poster is displayed at the PPP facilities for easy consultation by anyone interested and is also available in the platform website to provide wider support to scientists in overcoming common challenges in the recombinant protein field.

The development of this poster reflects the collective expertise of the Nanobiotechnology Group and PPP in the field of recombinant proteins, gained through years of hands-on research.

The development of this poster reflects the collective expertise of the Nanobiotechnology Group and PPP in the field of recombinant proteins, gained through years of hands-on research.
