Etat de l’art des ARN intérférents vectorisés par des nanoparticules lipidiques pour la reprogrammation des macrophages dans le cadre de l'immunothérapie du cancer
Etat de l’art des ARN intérférents vectorisés par des nanoparticules lipidiques pour la reprogrammation des macrophages dans le cadre de l'immunothérapie du cancer
Dans un article de revue publié dans Drug Delivery and Translational Research, des chercheurs de l’équipe INPACT de l’Institut Galien Paris-Saclay (IGPS, CNRS/UPSaclay, Orsay) font le point sur l’utilisation de nanoparticules dans les stratégies de reprogrammation des macrophages par interférence ARN dans le cadre de l'immunothérapie du cancer.   Les macrophages associés aux tumeurs (TAM) constituent le sous-type le plus abondant de cellules immunitaires présentes dans les tumeurs solides. Ils adoptent principalement un phénotype immunosuppresseur, contribuant ainsi à la progression tumorale. Une stratégie thérapeutique envisageable consiste à reprogrammer les TAM d’un état immunosuppresseur vers un état immunostimulateur en inhibant l’expression de protéines critiques au moyen d’ARN interférents (siRNA, miRNA et antagomirs). Cependant l’efficacité de cette approche reste limitée par la dégradation des ARN par les nucléases et par une pénétration cellulaire insuffisante. Ainsi cette revue décrit comment les nanoparticules lipidiques s’avérent très efficaces pour la vectorisation des ARN, notamment pour inhiber des médiateurs comme STAT6 et CSF-1R.   Malgré les résultats prometteurs des études précliniques, les auteurs analysent les différents obstacles qui doivent être surmontés pour permettre la transposition de cette approche à la pratique clinique. Il s'agit notamment de cibler efficacement les macrophages du microenvironnement tumoral, d'optimiser la pénétration intracellulaire des acides nucléiques et de minimiser les effets indésirables. Enfin, si l’injection intratumorale, utilisée dans la majorité des études, présente un intérêt certain, elle n’est pas adaptée à de nombreuses tumeurs. Dans ces cas, les auteurs soulignent l’importance de développer des stratégies de ciblage, notamment par l’utilisation de ligands spécifiques.   -> Contact : elias.fattal@universite-paris-saclay.fr / francois.fay@universite-paris-saclay.fr / juliette.vergnaud@universite-paris-saclay.fr

Quantum tunneling is the spooky phenomenon by which particles can cross through barriers that shouldn’t be surmountable. And it’s more than a textbook curiosity—photosynthesis relies on tunneling, as does nuclear fusion in the sun.
