Characterization of encapsulated porcine cardiosphere-derived cells for cardiac regeneration.

Researchers of NANBIOSIS U10 Drug Formulation unit of CIBER-BBN and UPV/EHU and NANBIOSIS U14 Cell Therapy unit and U24 Medical imaging unit at CCMIJU have participated in a research that proposes the use of encapsulated cardiosphere-derived cells (CDC), obtained from heart tissue, as regenerative cell therapy.

The encapsulation of the cells has been carried out in NANBIOSIS Unit 10, as well as the characterization of the cells (both encapsulated and unencapsulated) for their application in regenerative medicine (cardiac regeneration); and unit 14 of NANBIOSIS has obtained the cell model used for the study “ – Explains Kaoutar Ziani Akrirout, research scientists of CIBER-BBN and NANBIOSIS Unit 10.

These cells are multipotent stem cells, which secrete growth factors capable of promoting revascularization and healing of infarcted tissue. However, the use of this therapy faces a great challenge, which is the survival and retention of these cells after their implantation in the infarcted area, since the heart is a tissue that is constantly contracting and expanding, which leads to the loss of these cells, as they are carried along by the bloodstream.

To solve the low retention of cells, members of the NanoBioCel research team, from the CIBER-BBN and attached to the Bioaraba Health Research Institute (IIS Bioaraba), in collaboration with researchers from the IIS Aragón and the CIBERCV, propose the encapsulation of the CDC of porcine origin within a three-dimensional alginate-poly-L-lysine-alginate matrix as a therapy for cardiac regeneration, since, thanks to this, the encapsulated cells will be able to remain adhered to the tissue for longer, giving them time to exercise their function. The final objective will be to verify its efficacy in swine infarction models.

The team has verified that the phenotypic characteristics, the gene expression profile, the ability to differentiate to other cell lines and the release of growth factors from these cells are not altered by the encapsulation process, essential aspects given that their preservation it is essential for cardiac regeneration. In addition, this procedure keeps them viable for a month, which would favor the possible regeneration of the tissue.

On the other hand, that a sustained release of growth factors is maintained in these cells suggests that the implantation of encapsulated CDCs will promote the formation of new blood vessels and, consequently, the regeneration of infarcted cardiac tissue.

The researchers suggest that encapsulated CDCs could be a highly interesting therapeutic alternative in the field of cardiac regenerative medicine.

Reversing pulmonary fibrosis has been achieved in murine models with peptide-loaded nanoparticles

A new study with participation of NANBIOSIS Unit 10 Drug Formulation unit of CIBER-BBN and UPV/EHU, has succeeded in preventing and reversing pulmonary fibrosis in experimental models with PLGA / PEI nanoparticles loaded with the GSE4 peptide. These results are the first step to study its possible antifibrotic effect in patients with idiopathic pulmonary fibrosis and other progressive fibrosing diffuse interstitial lung diseases that present altered telomere function.

NANBIOSIS unit 10 has been responsible for the design and manufacture of biodegradable nanoparticles loaded with the peptide.

The work is led by Rosario Perona and Leandro Sastre, researchers of CIBERER at the Biomedical Research Institute (CSIC/UAM), and Maria Molina-Molina, researcher at CIBERES and the Department of Pulmonology at the Bellvitge University Hospital. In addition, Guillermo Güenechea, from CIBERER at CIEMAT-IIS / FJD, and José Luis Pedraz, from CIBER-BBN and the University of the Basque Country have collaborated.

Idiopathic pulmonary fibrosis is a fatal fibrotic disease associated with aging with a median survival of 2 to 5 years. The disease usually appears around the age of 60, but there are familiar forms that can manifest at younger ages. Fibrosis appears as an aberrant healing response after alveolar damage and is characterized by the appearance of abnormal lung scarring, in which the restoration of epithelial integrity and tissue function is compromised. The mechanisms responsible for defective repair and regeneration are not well understood. However, recent studies suggest a possible role of accelerated aging and telomere shortening in the onset of the disease, mainly in familial forms.

The GSE4 peptide, of 11 amino acids, corresponds to an internal sequence of dyskerin, a protein that is part of the telomerase complex. GSE4 has protective effects on the cells of patients with the rare diseases dyskeratosis congenita and ataxia-telangiectasia, as it increases telomerase activity and cell growth and reduces DNA damage, oxidative stress and cell senescence.

The authors of the study, published in The FASEB Journal, used rat lung alveolar cells treated with a profibrotic agent, bleomycin, as a model. Expression of the GSE4 peptide or treatment with GSE4-PLGA / PEI nanoparticles causes a reversal of the inflammatory and fibrotic phenotype. There is an increase in telomerase activity, a decrease in DNA damage, and a decrease in inflammation and cell death. Furthermore, these cells show an inhibition in fibrosis.

In a rat model with bleomycin-induced pulmonary fibrosis, treatment with GSE4-PLGA / PEI nanoparticles has also increased telomerase activity and decreased DNA damage in alveolar cells. In both preventive and therapeutic protocols, GSE4-PLGA / PEI nanoparticles have prevented and attenuated lung damage and inhibited fibrosis. Histological analysis of the lungs of rats treated with bleomycin and GSE4-PLGA / PEI nanoparticles shows less fibrosis and inflammation and greater regeneration of the alveolar tissue, indicating the therapeutic efficacy of GSE4-loaded nanoparticles in this experimental pulmonary fibrosis model. .

This study supports the possibility of further investigating a potential curative treatment for patients with pulmonary fibrosis.

(*) Explanation of the figure: Treatment with the profibrotic agent bleomycin decreases the number of cells that express the alveolar marker proSP-C (Bleo). Inoculation of GSE4-loaded nanoparticles into bleomycin-treated rats increases the number of cells expressing the marker, indicating alveolar regeneration.

Non-viral mediated gene therapy in human cystic fibrosis airway epithelial cells recovers chloride channel functionality

Researchers of CIBER-BBN Units of NANBIOSIS: U29 Oligonucleotide Synthesis Platform (OSP) at IQAC_CSIC, led by Prof. Ramón Eritja and U10 Drug Formulation, at UPV-EHU, led by Prof José Luis Pedraz, are coauthors of an article published by International Journal of Pharmaceutics.

Gene therapy strategies based on non-viral vectors are currently considered as a promising therapeutic option for the treatment of cystic fibrosis (CF), being liposomes the most commonly used gene carriers. Niosomes offer a powerful alternative to liposomes due to their higher stability and lower cytotoxicity, provided by their non-ionic surfactant and helper components. In this work, a three-formulation screening is performed, in terms of physicochemical and biological behavior, in CF patient derived airway epithelial cells. The most efficient niosome formulation reaches 28% of EGFP expressing live cells and follows caveolae-mediated endocytosis. Transfection with therapeutic cystic fibrosis transmembrane conductance regulator (CFTR) gene results in 5-fold increase of CFTR protein expression in transfected versus non-transfected cells, which leads to 1.5-fold increment of the chloride channel functionality. These findings highlight the relevance of niosome-based systems as an encouraging non-viral gene therapy platform with potential therapeutic benefits for CF.

How to delay vision loss in hereditary retinal dystrophies? Looking for the most effective and economical pharmacological nanotherapy

Researchers from the CIBER-BBN and NANBIOSIS are participating in a new project that aims to achieve the most effective, specific and economical pharmacological nanotherapy that allows delaying the death of retinal cells and subsequent loss of vision in hereditary retinal dystrophy. retinitis pigmentosa, regardless of the genetic defect causing the disease.

In this project, coordinated by the researcher Regina Rodrigo, the ONCE and the Prince Felipe Research Center (CIPF) of Valencia collaborate, together with researchers from the CIBER of Rare Diseases (CIBERER) and the Manises Hospital in Valencia. On behalf of the CIBER-BBN, the scientific director, Ramón Martínez Máñez, together with Elena Aznar from the IDM-UPV group of the Polytechnic University of València, José Luís Pedraz, Gustavo Puras and Idoia Gallego, from the group of the University of the Basque Country and Nanbiosis.

The NANBIOSIS participation in the project will be through the U10 Drug Formulation unit (from @CIBERBBN and @upvehu), led by NanoBioCell Group and Prof. José Luis Pedraz and U26 NMR: Biomedical Applications II , led by IDM-UPV-UV Group, led by Prof. Ramón Martínez Máñez. Elena Aznar, researcher of CIBER-BBN at IDM-UPV-UV explained “We use the unit to characterize the nanoparticles. Through a solid phase NMR confirms that the molecular gate has been correctly attached to the surface of the nanoparticles“.

Retinitis pigmentosa is a group of inherited retinal dystrophies characterized by progressive and irreversible loss of vision. Although it is considered a rare disease, it is the leading genetic cause of blindness in developed countries. So far there is no effective treatment, although there are various therapeutic approaches such as gene therapy, cell therapy, pharmacological therapy, optogenetics or electronic implants.

During the progression of the disease, an important inflammatory component has been observed that may contribute to its pathogenesis. In this sense, different anti-inflammatory strategies have been evaluated. The research group has successfully tested one of these strategies in preclinical models of retinitis pigmentosa. However, the implementation of this therapeutic strategy with nanocarriers as controlled release delivery systems would improve the mode of action of the administered drug, avoiding its degradation, increasing its half-life, stability or its availability in the retina. In this project, two types of nanocarriers will be used and their effect on the degenerative process in a murine model of retinitis pigmentosa will be evaluated.
