Engineering nanotechnology to unleash RNA therapeutics’ full potential

Dr. Roy van der Meel,
Assistant Professor in the Precision Medicine group. Institute for Complex Molecular Systems en Biomedical Engineering, TUE

Abstract

Nucleic acid therapeutics harbor great potential for silencing, expressing, or editing genes. However, nucleic acid-based drugs require chemical modifications and sophisticated nanotechnology to prevent their degradation, reduce immunostimulatory effects, and ensure intracellular delivery [1].

Lipid nanoparticle (LNP) technology is the current gold standard delivery platform technology that has enabled the clinical translation of the first siRNA drug Onpattro [2] and the COVID-19 mRNA vaccines [3].

Nevertheless, currently approved LNP systems are mostly suited for vaccine purposes following local administration or hepatic delivery following intravenous administration [4].

To unleash RNA therapeutics’ full potential, nanotechnology with tuable biodistribution needs to be established that enables safe and delivery of nucleic acid drugs following systemic administration.

During this talk, I will discuss LNP delivery technology and focus on important aspects that have enabled its clinical translation such as development of ionizable cationic lipids. In addition, I will provide examples of therapeutic applications and highlight developments beyond the-state-of-the-art including engineering nature-inspired nanoplatform technology for systemic nucleic acid delivery to immune cells using apolipoproteins [5].

CV

Roy van der Meel is a biomedical engineer specialized in nanomedicine and RNA therapeutics.

After obtaining a PhD from Utrecht University under guidance of prof. dr. Wim Hennink and prof. dr. Gert Storm, and a postdoc appointment at the University Medical Center Utrecht in prof. dr. Raymond Schiffelers’ lab, he secured Marie Skłodowska-Curie and Dutch Research Council (NWO) Veni funding to move to prof. dr. Pieter Cullis’ lab at the University of British Columbia in Vancouver, Canada.

During his 3.5-year postdoctoral tenure, he gained extensive experience with developing lipid nanoparticle (LNP) technology that enabled the approval of the first siRNA therapeutic and the COVID-19 mRNA vaccines. 

In 2019, he was recruited to the Eindhoven University of Technology by prof. dr. Willem Mulder and appointed Assistant Professor in the Precision Medicine group. 
His current research is supported by NWO Vidi funding and focuses on establishing platform nanotechnology for delivering RNA therapeutics to specific immune cells. 

He has co-authored over 50 publications in leading nanotechnology-focused journals including Nature Nanotechnology, Nature Biomedical Engineering, and ACS Nano.

Nieuwe Locatie

Vanaf 1 september 2023 zullen onze bijeenkomsten plaatsvinden in Avans Hogeschool, Onderwijsboulevard 215, 5223 DE ‘s-Hertogenbosch.

Omdat het Rode Kruisgebouw, waar we tot nu toe onze bijeenkomsten hielden, sinds dit jaar in de verkoop staat, is het bestuur op zoek gegaan naar een geschikte nieuwe locatie.

Dat is Avans Hogeschool geworden;

  • omdat er een link is met onze activiteiten m.n. de opleiding chemie
  • een centrale ligging heeft, 10 minuten lopen vanaf station Den Bosch Centraal
  • Avans heeft mooie ruimtes ter beschikking met goede presentatiemiddelen.

    Zie ‘Locatie‘ voor plattegrond en looproute.
