METHODS FOR TREATING NETOSIS AND NEUTROPHIL ACTIVATION

Resumen de: US20260077028A1

Described herein are methods and compositions relating to methods of inhibiting neutrophils, e.g., inhibiting NET release or NETosis, by means of a DEspR inhibitor, e.g., an anti-DEspR antibody reagent. In some embodiments, the methods can relate to the treatment of a disease, e.g., cancer or a disease wherein neutrophils; NETs; or NETosing or NETting neutrophils contribute to pathogenesis, chronicity, or worsening of disease. In some embodiments, the DEspR inhibitor can be a bi-specific reagent or an antibody-drug conjugate.

Resumen de: US20260077038A1

The present disclosure provides for improved compositions of ionizable lipid nanoparticles for the delivery of therapeutic nucleic acids to cells. Anionic phospholipids, including phosphatidylserine and phosphatidylglycerol are included in the lipid nanoparticles to increase the transfection efficiency in human dendritic cells. The further incorporation of mono-unsaturated alkyl chain analogs in dimethylaminopropyl-dioxolane or heterocyclic ketal ionizable lipids in the formulation demonstrated high levels of transfection in human dendritic cells, compared to other ionizable lipids in the same family, and demonstrated good stability to oxidative damage. Finally, the use of an ammonium salt of phosphatidylserine allows for the efficient production of PS-targeted LNPs.
