Developing methods for delivery of Oligonucleotide conjugates as therapeutics at Karolinska Institutet

Research description

Developing new methods for improving action of therapeutic modalities like oligonucleotides, peptides and bioconjugates is a fundament of my research at KI. I examine a range of scientific tools with the aim to improve targeting therapeutics to precise destination in the body, contributing to the discoveries of the future precise therapies. Many therapeutic approaches can be improved and unwanted side effects avoided. We should design therapeutics in such a way that they will be delivered and released precisely to the affected organ/tissue in the body (targeted delivery approach).

As a part of European network I am applying developed at KI methods for improvements of oligonucleotide based therapies (e.g. COST Action: Delivery of Antisense RNA Therapeutics). As a bioconjugation chemist I seek interdisciplinary collaborations with medicinal, biological and biochemical experts to explore the potential of the methods I developed to improve therapies. Some of the key collaborators include: Prof. Aartsma-Rus at the Leiden University Medical Center (LUMC), The Netherlands, and Shalini Andersson Chief Scientist New Therapeutic Modalities at AstraZeneca, Gothenburg.

After working on several projects developing more effective therapeutics I recognize the importance of finding solution to the general problem of their precise delivery. Methods that I developed at KI allows for efficient conjugation of receptor specific entities to oligonucleotides. That improves delivery of those molecules to the place of action. However, ligand-receptor interaction is usually weak, and current methods allow for conjugations of just several such ligands to oligonucleotide. On the other hand, exosomes that are 30-200 nm in diameter, can be equipped with several hundreds of copies (~ 600, depending of the EVs size) magnifying the targeting effect. This is the reason why bio-engineered EVs may be just the answer that scientists are looking for in targeted drug delivery and a main collaborative project at the moment.
