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.

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.

As we leave World Colorectal Cancer Day 2024 behind, marked on March 31st, there have been significant highlights in cancer treatment, a field in which targeted therapies are playing a crucial role.

In this context, researchers from the Nanobiotechnology team, at the Institut de Biotecnologia i de Biomedicina from Universitat Autònoma de Barcelona, led by Prof. Antonio Villaverde, in collaboration with the Oncogenesis and Antitumor Drugs team led by Prof. Ramón Mangues at Institut de Recerca Sant Pau, have made a significant breakthrough in the treatment of colorectal cancer. Their innovative approach, facilitated by their respective Unit 1 and Unit 18 of NANBIOSIS, promises to revolutionize current treatment methodologies and improve patient outcomes.

“In a clinical context, the use of these materials in the treatment of colorectal cancer should greatly improve the drug’s efficacy and patient comfort while minimizing unwanted side effects.”
Prof. Antonio Villaverde, Strategy Director of Unit 1

“It is important to highlight that such accumulation is more effective than when the protein is administered into the bloodstream. This fact offers a new and unexpected way to ensure high local levels of the drug and better clinical efficacy, avoiding repeated intravenous administration regimens,” explains Prof. Villaverde. “In a clinical context, the use of these materials in the treatment of colorectal cancer should greatly improve the drug’s efficacy and patient comfort while minimizing unwanted side effects.”

The team’s groundbreaking research centers around the development of self-contained protein-only materials at the microscale, capable of delivering therapeutic polypeptides in a time-prolonged manner. These materials, resembling the organization of secretory granules within the human endocrine system, are engineered to release functional polypeptide nanoparticles. These nanoparticles can selectively target tumors and destroy specific types of cancer cells, offering a promising avenue for more effective and precise cancer treatment.

The publication:

Notably, the researchers thorougly explored the molecular structure and dynamics of the secretion process of these materials, both in vitro and in vivo. In preclinical trials using an animal model of colorectal cancer, the system demonstrated remarkable efficacy upon subcutaneous administration. This was thanks to the released protein nanoparticles accumulating efficiently in tumor tissues. Importantly, this accumulation was found to be more effective than traditional intravenous administration methods, offering a novel strategy to ensure high local drug levels while minimizing systemic side effects.

‘Magic Bullets’ Against Cancer: Unveiling the Potential of DNA Nanoparticles

DNA nanoparticles to selectively target tumor tissues through precise control of the synergies between transported drugs.

February 2024, IQAC-CSIC/CIBER-BBN, Barcelona. The team led by Drs. Carme Fàbrega and Ramón Eritja, in close collaboration with 3 units of the NANBIOSIS ICTS, has developed a new strategy to improve the efficacy and reduce the toxicity of anticancer drugs. They have chemically linked several cytotoxic drugs, currently used in the treatment of various types of tumors, to DNA nanostructures. These structures selectively target cancerous tissues through folate receptors. This tactic allows precise control of drug concentration and exploits their combined effect. The results of this study represent a significant step forward towards the development of more effective and safer cancer treatments. This year 2024, they published their study in the Nanomedicine journal by Elsevier.

“The ‘Magic Bullet’ of Dr. Ehrlich” is not the title of an old pulp magazine. Rather, it is the concept that the German physician and Nobel Prize winner coined to refer to an ideal therapeutic agent capable of acting specifically against a particular disease without affecting healthy cells.

In the case of cancer therapies, we are far from reaching that magic bullet. However, science is bringing us closer to it every day.

Many current anticancer drugs are designed to intercalate into the DNA of cells and alter their function, inducing cell death. One of the most significant problems with these therapies is their adverse effects, as these drugs can also affect non-tumor cells. One way to compensate for this is by combining multiple drugs, creating synergies between them. However, this often greatly hinders both drugs from reaching the target tissue at the appropriate concentrations to exert their synergy.

A strategy to approach the concept coined by the Nobel Prize involves selectively directing drugs towards cancerous tissues and releasing them in a controlled and localized manner. This increases their concentration in the tumor area, reducing the effect on the rest of the organs and tissues.

Thanks to the ability of many drugs to intercalate into DNA, one of the most promising vehicles are DNA nanostructures. These artificially constructed nanocarriers can retain the drug and, due to their enormous versatility, can be designed to selectively target the tumor. Once there, they release the drug in a controlled manner into the cancer cells, ensuring that healthy tissues are not exposed to a toxic concentration of the drug.

However, these DNA nanocarriers face several challenges: low internalization in diseased cells, low selectivity of the target tissues, or limited control over the amount of drug loaded inside and how it binds. Additionally, they only allow the transport of DNA intercalating drugs, limiting the range of applicable therapies.

In a recent study published in the Nanomedicine journal by Elsevier, the team led by Dr. Carme Fàbrega and Dr. Ramón Eritja, in close collaboration with 3 units of the NANBIOSIS ICTS, present a new approach [1]. Through a strategy to control the binding of the drug and its concentration within their DNA nanostructures, they have succeeded in increasing efficacy and reducing toxicity.

Instead of intercalating the drugs as usual, the researchers chemically conjugated each drug to a piece of the puzzle that would later form the nanostructure. They managed this way to precisely attach three anticancer drugs to their vehicles, each of them acting on a different anticancer mechanism and promoting a synergistic effect between them. Additionally, they achieved selective targeting by binding their nanostructures to folate receptors, expressed massively in a wide variety of tumor types.

This pioneering methodology is capable of attaching multiple drugs to DNA nanostructures, each at predetermined concentrations. This represents a leap forward in advancing towards the generation of that effective and harmless magic bullet that Dr. Ehrlich envisioned.

Good News! Protein Nanoparticles with a New Ligand Select and Destroy Tumor-associated Fibroblasts”

With the participation of two units of NANBIOSIS ICTS and the expertise of the scientists managing these units

The study, fruit of the collaboration between the Nanotechnology group of the Institute of Biotechnology and Biomedicine (IBB-UAB), led by Prof. Antonio Villaverde, and the Oncogenesis and Antitumor Drugs group of the Sant Pau Research Institute, led by Dr. Ramon Mangues, both members of CIBER-BBN, has made significant progress by identifying the natural ligand PDGFD as an effective tool to target protein nanoparticles to tumor-associated fibroblasts that overexpress the PDGFR-β receptor. Given the relevance of the discovery, this technology has been intellectually protected by a patent that is currently being processed (PCT/EP2023/081937).

The research, the details of which have recently been published in the journal Acta Biomaterialia, presents an innovative strategy focused on the development of protein nanoparticles that assemble autonomously and are capable of selectively recognizing and destroying tumor-associated fibroblasts with high levels of PDGFR-β. This cell type plays a fundamental role in the tumor microenvironment, providing mechanical and biological support for tumor growth and progression in various types of cancers.

Taking advantage of their solid experience in the development of tumor-targeting protein nanoparticles and their functional characterization in in vitro and in vivo models of different types of cancer, both groups set out on this occasion to design new nanoparticles targeting tumor-associated fibroblasts with PDGFR-β overexpression. Among the different ligands tested, PDGFD has been selected for its ability to induce selective penetration into target cells both in vitro and in vivo, using a murine model with a subcutaneous tumor. In these experiments, the PDGFD-GFP-H6 fusion protein, formed by the chosen ligand, the green fluorescent protein and a histidine tail with an important role in obtaining nanoparticles, accumulates precisely in tumor tissues, demonstrating its ability from being delivered in tumor.

By replacing GFP with a microbial toxin present in antitumor treatments approved for clinical use, a significant reduction in tumor volume growth is observed, without showing toxic collateral effects in mice. In this way, the PDGFR-β/PDGFD couple has been validated as a versatile tool for the targeted delivery of drugs to the tumor microenvironment. These promising results pave the way for future developments in nanomedicine and offer new hope in the search for more effective and less invasive treatments for cancer patients.

The research has been performed with the collaborative participation of two units of the ICTS “NANBIOSIS”, more specifically the units U1 of Protein Production Platform, PPP and U18, Nanotoxicology Unit, and is framed in the context of the intramural collaboration of the CIBER-BBN “FIBOLISM”, coordinated by Dr Lorena Alba Castellon.

NANBIOSIS has been represented at this edition by members of several of its units, among them we must highlight the set of four oral communication presented by members of the Nanobiotechnology group-Unit 1 of NANBIOSIS “Protein Production Platform (PPP)”, from CIBER-BBN and IIB-UAB the talks were delivered by:

Eloi Parladé: “Development of ion-dependent microscale secretory granules for nanomedical applications”

Carlos Martínez-Torró: “Design of a human GFP-like protein scaffold for targeted nanomedicines”

Eric Voltá Durán: “Antitumoral nanoparticles with multiple activities, a close reality”

Jan Atienza-Garriga: “Characterization of protein-only NPs containing amps and analysis of their protection with liposomes and micelles”

They summarized a wide area of the team activities on the design of protein-based protein materials for clinical uses, produced by means of diverse types of cell factories. In particular, antimicrobial peptides, cytotoxic proteins with antitumoral targeting and drug-carrying scaffold proteins are engineered to confer self-assembling properties as either microparticles or nanoparticles, that can be further functionalized with chemical drugs through covalent binding. Microparticles are of special interest as they can be used as slow drug delivery systems for nanostructured drugs upon subcutaneous administration. Alternatively, nanoparticles can be also presented as embedded in liposomes or other micellar structures that stabilize them for enhanced performance.

Three NANBIOSIS units supported the presented research, which has been executed in a highly cooperative way: namely U1 (Protein Production Platform), led by Tony Villaverde U18 (Nanotoxicology), led by Ramón Mangues and U29 (Oligonucleotide Synthesis Platform), led by Ramón Eritja.

Among all the excellent contributions by the team, it is worthy to stress that the prize for the best Oral Presentation was granted to Dr Eloi Parladé.

Other talk by researchers from NANBIOSIS were “Antioxidant-loaded polymeric NPs prepared by nano-emulsion templating for the management of neurological diseases” by Santiago Grijalvo, from NANBIOSIS U12 and “Exploiting GSH oxidation with nanocatalysts to promote cancer cell death” by Javier Bonet-Aletá from NANBIOSIS U9

On the other hand, Jesús Santamaría, Scientific Director of NANBIOSIS U9 was a Keynote Speaker in the Conference with the talk: “A change of paradigm in cancer therapy? Using catalysts to make drugs inside the tumor, rather than trying systemic chemotherapy”

NALS 2022 has been an excellent conference, with presentations covering a wide range of topics in nanomaterials for health, and a great opportunity for our researchers, especially for young’s, to let know their collaborative work, as well as make new connections on common research interests, thanks to the good socializing opportunities afforded by the scheduling of the organization conference.
