Nanomedicine in B·Debate Fighting Blindness by Unit 10 of NANBIOSIS

The recent published Newsletter of Institut of Màcula and the Barcelona Màcula Foundation: Research for Vision reported about the forum  B·Debate Fighting Blindness. Future Challenges and Opportunities for Visual Restoration, September 6-7 , that gathered more than thirty experts in the different areas related with blindness.

The second Session, about Nanotechnology and Nanomedicine, was chaired by Jose Luis Pedraz, Scientific Director of Unit 10 of NANBIOSIS and Gustavo Puras Ochoa, researcher  of the group Nanobiocel, which coordinates Unit 10 of NANBIOSIS gave a lecture “Non-viral gene delivery for the treatment of inherited retinal disorders” :

Many devastating blinding disorders that affect the retina in the developed world have a well-known genetic background. Despite gene therapy strategies have made major advances in recent years, many of the patients affected by inherited retinal diseases must live under impaired vision, even with the best medical treatment. Therefore, the development of effective gene carriers represents a major challenge for the scientific community. At present, viral and non-viral vectors are the most employed approaches to deliver genetic material to the retina. Although first promising clinical trials results with viral vectors offer reasonable hope to patients affected by some inherited diseases that cause irreversible blindness such as Retinitis Pigmentosa, Stargardt´s disease, Choroideremia and Age related Macular Degeneration, important concerns related to the risk of oncogenesis, immunogenicity, inflammatory responses, and the persistence of viral vectors in brain after intravitreal injection have garnered the interest to invest on non-viral gene transfer methods. Compared with their counterparts, non-viral vectors offer many important advantages, since are less limited by the size of the gene to transfect, do not raise major safety concerns, are easier and cheaper to produce, and are classified as drugs rather than as biologist by the regulatory authorities.

Micro and nano capsules that will increase the effectiveness and precision of medicine.

José Luis Pedraz, Scientific Director of Unit 10 of NANBIOSIS and members of NANOBIOCEL group, which coordinates Unit 10 of NANBIOSIS, explain for the TEKNOPOLIS program of EiTB, the first communication group in the Basque Country, the development of micro and nanocapsules, gels and scaffolds to solve the problems of administration of new drugs.

The new active principles – says Pedraz – that have emerged in recent years from studies of genetic engineering, the production of recombinant proteins and others, have generated new molecules whose characteristics are very different from the conventional active ingredients of chemical synthesis and have raised a series of problems with their administration that do not solve the classic pharmaceutical formulas of the type of tablets, capsules or injectables, this is the  reason why it is necessary to develop new systems of administration based on micro and nano technologies that can be administered in a correct and efficient way for patients. These devices can be used for transplantation and treatment of different diseases such as Parkinson, Alzheimer or Diabetes.

“It is necessary to increase our relationship with European research groups” by José Luis Pedraz – U10 of NANBIOSIS

Last Sunday, November 27, the Newspaper of Álava published a special supplement with the title “ALAVA 2020”. It contained an article by José Luis Pedraz (Scientific Director of Unit 10 of NANBIOSIS)

According to Dr. Pedraz, group leader of the CIBER-BBN NANOBIOCEL group, in the next future, important challenges with new technologies will allow a considerable advance in the treatment of diseases of genetic origins. In this context, it is crucial to increase the number of international contacts in order to be able to access new infrastructures more competitively. The opening of new lines of research and the creation of new research infrastructure through consortiums such as CIBER-BBN or the Unique Scientific and Technologic Infrastructure (ICTS) NANBIOSIS generate an advantageous situation to attract new investments and create new companies. Pedraz continues explaining that we must increase our relations with European research groups in order to build consortia with which participate in for European research calls.

The NANOBIOCEL Group, coordinator of Unit 10 of NANBIOSIS, currently participates in two European consortiums (DRIVE Project) and (BERENICE Project) .

Cationic nioplexes in supramolecular hydrogels as hybrid materials to deliver nucleic acids

Jose Luis Pedraz, Scientific Director of Unit 10 of NANBIOSIS and Ramon Eritja (CIBER-BBN) have participated in the entrapment of cationic nioplexes in supramolecular hydrogels and the use of these materials for transfecting cells.

This work is focused on entrapping cationic nioplexes within supramolecular hydrogels based on N-protected phenylalanine. To modulate the supramolecular hydrogel diffusion properties, hydrogels were easily tuned with ĸ-carrageenan (≤ 1%). These materials were fully characterized using rheology. The niosomal liberation in solution through hydrogels was monitored by fluorescence and this release was controlled by diffusion mechanisms. The lack of toxicity of these materials allowed these materials to be used in cell culture. Preliminary transfection results confirmed the suitability of entrapping niosomal formulations in supramolecular hydrogels and the potential opening up of alternative strategies in therapy.

This study was published in RSC Advances:

Diabetes mellitus is a chronic disease characterised by high blood sugar (glucose).  If not treated carefully, diabetes causes several debilitating side effects including heart disease, damage to the eyes, kidneys and nerve endings (e.g. hands, feet) and can lead to premature death. The total number of people living with diabetes in Ireland is estimated to be over 225,000.  According to the international diabetes federation (IDF), 382 million people worldwide have diabetes and in 2013 an estimated 5.1 million deaths were attributable to the disease, representing 8.4% of global adult mortality. Blood glucose is high in diabetes because of the inability of the pancreas to produce sufficient insulin, a hormone that controls blood sugar. Currently the main treatment for diabetes is the daily injection of insulin. In patients where control is poor, transplantation of pancreatic cells (which contain insulin-producing β-cells) is possible. However there are challenges with this therapy including the short supply of donor pancreases, the need to use 3-4 pancreases to get enough β-cells for treatment and poor graft survival and retention at the transplant site.

The DRIVE consortium will address these challenges by developing a completely new system to deliver pancreatic β-cells effectively in a targeted and protected fashion. This will mean that fewer donor pancreases are needed for cell transplantation allowing more patients to avail of a more effective longer-lasting treatment with less demand on donor pancreases. Additionally, the consortium will investigate the combination of DRIVE’s technology with future stem cell-derived β-cells that will widen the availability of islet transplantation therapy to all insulin-dependent patients.

Dr. José Luis Pedraz, commented on the research funding: “We are delighted to participate in the DRIVE programme to translate new collaborative research for the benefit of patients with diabetes mellitus.  Regenerative medicine and stem cell therapies have the potential to revolutionise the treatment of patients who have diabetes, and through DRIVE we will develop new technologies to enhance stem cell therapies for these patients by increasing targeting and ease of delivery using advanced biomaterials.”

DRIVE’s β-System consists of a β-Gel, which contains the pancreatic β-cells within a pancreas mimicking gel; which itself is protected within a capsule called a β-shell. This is delivered using a specialised injection catheter, called β-cath, which offers a more minimally invasive surgical procedure than is currently used.

The current transplantation technique offers patients natural glucose control for 1-2 years. DRIVE’s β-system aims to provide control for up to 5 years by increasing the longevity of the β-cell transplant. The system offers further advantages through the slow release of immunosuppressant drugs by the β-shell, reducing the patient’s need for long-term anti-rejection medication, which has harmful side effects. The β-shell will also be retrievable, so it can be removed and replenished after the 5-year period. DRIVE’s 5-year work plan will include animal testing, with a view to human testing at the end of the project.

Professor Paul Johnson, Director of the Oxford Islet Transplant Programme and Professor of Paediatric Surgery at the University of Oxford, said: “Over the past 10 years, the transplantation of insulin-producing pancreatic cells known as islet cells (that can sense blood sugar levels and release insulin to maintain normal sugar levels) has achieved very promising results in adults who have developed the severest complications from insulin-dependent diabetes. The challenge is to now make sure that more people can benefit from this minimally-invasive treatment. Ultimately we would hope that it can be used to reverse diabetes in children soon after diagnosis. The DRIVE Consortium brings together some of the leading researchers in Europe in the fields of bioengineering, cell biology, and cell transplantation. The overall aim is to develop novel membranes to protect the transplanted islets from rejection ensure that islet transplantation can be undertaken without the need for the patient to take anti-rejection medication, with all the associated complications. This programme of research could be a real game-changer for people with Type 1 diabetes and the team in Oxford are very excited to be part of this state of the art research collaboration.”

The DRIVE Consortium represents a major interdisciplinary effort between stem cell biologists, experts in advanced drug delivery, research scientists, clinicians and research-active companies working together to develop novel therapeutics to address the challenges of treating diabtes. The researchers will optimise adult stem cell therapy using smart biomaterials and advanced drug delivery, and couple these therapeutics with minimally-invasive surgical devices.
