Abstract: Disclosed herein are recombinant AAV variant (e.g., variant serotype 3B (AAV3B)) capsid proteins and variant capsid protein-containing viral particles with enhanced ability to transduce hepatic cells. Viral particles containing these capsid variants are capable of evading neutralization by the host humoral immune response. The recombinant AAV3B variant proteins and viral particles disclosed herein were identified from a variant AAV3B capsid library that was engineered by making substitutions in only the variable regions of the capsid. Some embodiments of the AAV3B capsid variants disclosed herein comprise the AAV3B-G3 variant and the AAV3B-E12 variant. Compositions of these variant AAV particles are provided that are useful for transducing and delivering therapeutic transgenes to cells, such as liver cells, and thus treat diseases and disorders pertaining to these cells.

Abstract: Systems and methods are provided for trapping and electrically monitoring molecules in a nanopore sensor. The nanopore sensor comprises a support structure with a first and a second fluidic chamber, at least one nanopore fluidically connected to the two chambers, and a protein shuttle. The protein shuttle comprises an electrically charged protein molecule, such as Avidin. The nanopore can be a Clytosolin A. A method can comprise applying a voltage across the nanopores to draw protein shuttles towards the nanopores. The ionic current through each or all of the nanopores can be concurrently measured. Based on the measured ionic current, blockage events can be detected. Each blockage event indicates a capture of a protein shuttle by at least one nanopore. Each blockage event can be detected through a change of the total ionic current flow or a change in the ionic current flow for a particular nanopore.

Abstract: The disclosure relates to methods and compositions for regulating expression of DUX4. Specifically, the disclosure provides a recombinant gene editing complex comprising: a recombinant gene editing protein; and, a nucleic acid encoding a guide RNA (gRNA) that specifically hybridizes to a target nucleic acid sequence encoding a D4Z4 macrosatellite repeat region, wherein binding of the complex to the target nucleic acid sequence results in inhibition of DUX4 gene expression. In some aspects, methods described by the disclosure are useful for treating a disease associated with aberrant DUX4 expression (e.g., facioscapulohumeral muscular dystrophy, FSHD).
