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.

NANBIOSIS lecturers in B-Debate Imaging for Life. From Molecules to Diagnostics and Therapy

Last November took place in CosmoCaixa, Barcelona, the B-Debate Days Imaging for Life. Molecules from Diagnostics and Therapy.

The event, organized by B·Debate (an initiative of Biocat and “la Caixa” Foundation), IBB and LJS, was focussed on Biomolecular Imaging, with emphasis on molecular, cellular, tissular and small animal research, as well as biomedical applications, including noninvasive diagnostics, image guided surgery, multimodal imaging and theranostics.

Scientists of NANBIOIS Unit 20 and 25 were invited to participate as guest lecturers:

-Simó Schwartz, Scientific Director of Unit 20: New bioluminescent models to target cancer stem cells with nanomedicine.

-Ana Paula Candiota, Scientific Coordinator of Unit 25: Unravelling therapy response in preclinical glioblastoma using MRSI-based molecular imaging and source analysis.

As Professor Candiota explained “Characterization of Glioblastoma (GB) response to treatment is a key factor for improving patient survival and prognosis. Magnetic Resonance Imaging and Spectroscopic Imaging (MRI/MRSI) provide morphologic and metabolic profiles of GB but usually fail to produce unequivocal surrogate biomarkers of response. Ideally, we would like to provide clinicians with early therapy response follow-up and an improved time frame for changing or adapting therapy schemes”. Her talk focussed in the capability of advanced pattern recognition techniques, such as semi-supervised signal source extraction, to produce nosological images with robust recognition of response to temozolomide (TMZ) in preclinical GB (GL261 tumour-bearing in immunocompetent C57BL/6 mice) through the information contained in MRSI grids. These techniques have a clear translational potential and could improve future patient management and care. The acquisition of mice MRSI data used for pattern recognition strategies development and evaluation was performed in the Biospec 7T scanner from U25.
