  • Patent number: 11332502
    Abstract: Adeno associated viral (AAV) particles are emerging as a useful vehicle for gene delivery to various organs and tissues, one of them being the retina. Provided here are variant AAV (e.g., variant serotype 2 (AAV2)) capsid proteins and variant capsid protein containing particles with enhanced ability to transduce retinal cells.

  • Publication number: 20210290771
    Abstract: Provided herein are compositions and methods related to targeted delivery of a therapeutic or diagnostic agent to a subject utilizing an engineered receptor-ligand system, such as an engineered dockerin-cohesin system. As described herein, previously-developed targeted delivery systems for delivering therapeutic and diagnostic agents to a tissue of interest have drawbacks that have not been addressed to date. For example, with respect to the blood-brain barrier (BBB) and the blood-cerebrospinal fluid barrier (BCSFB), both of which hamper delivery of agents to the brain, others have relied on the use of endogenously expressed receptors, like the transferrin receptor, to assist the agent across the barriers.
