An Expanded Toolbox for Versatile Chemical Editing of Adeno‐Associated Virus

Angewandte Chemie, EarlyView.
We describe technology to introduce diverse non‐natural chemical functionalities site‐specifically into the capsid of adeno‐associated virus through genetic code expansion, and using them to engineer this leading vector for human gene therapy for enhanced tissue specificity and reduced immunogenicity Abstract Site‐specific incorporation of noncanonical

Identifying optimal capsid duplication length for the stability of reporter flaviviruses

Emerging Microbes and Infections, 2020
Mosquito-transmitted flaviviruses cause widespread disease across the world. To provide better molecular tools for drug screens and pathogenesis studies, we report a new approach to produce stable NanoLuc-tagged flaviviruses, including dengue virus ...

ICTV Virus Taxonomy Profile: Chrysoviridae [PDF]

, 2019
Members of the family Chrysoviridae are isometric, non-enveloped viruses with segmented, linear, dsRNA genomes. There are 3–7 genomic segments, each of which is individually encapsidated.

Physical properties of the HIV-1 capsid from all-atom molecular dynamics simulations

Nature Communications, 2017
Human immunodeficiency virus type 1 (HIV-1) infection is highly dependent on its capsid. The capsid is a large container, made of ∼1,300 proteins with altogether 4 million atoms.

Alphaviral Capsid Proteins Inhibit Stress Granule Assembly via Competitive RNA Binding With G3BP1

Advanced Science, EarlyView.
Stress granules exert antiviral functions. This study illustrates a conserved function of alphaviral capsid proteins in modulating stress granules. Oligomerization mediated by a helical motif coupled with a positively charged intrinsically disordered region (IDR) directly competes with G3BP1 for RNA binding, thereby disrupting G3BP1‐RNA liquid–liquid ...

A Nonviral Neo‐Nucleocapsid for Cell‐Specific RNA Delivery Developed by Pseudo‐Cyclic Peptide Grafting and Directed Evolution

Angewandte Chemie, EarlyView.
Nonviral neo‐nucleocapsids developed from a repurposed bacterial protein cage, and macrocyclic peptide pharmacophores via protein‐protein ligation, bacteria‐based directed evolution, lasso‐grafting, and mammalian cell‐based directed evolution enabled cell specific RNA delivery.

Engineered Small Extracellular Vesicles Targeting Tumor‐Associated Endothelial Cells to Effectively Remodel the Glioma Microenvironment

Advanced Science, EarlyView.
This study developed a novel drug delivery platform that overcomes the blood‐brain barrier in glioblastoma. By fusing IGFBP7 with small extracellular vesicles, the platform specifically targets tumor vasculature. It effectively delivers temozolomide, suppressing tumor growth at low doses.

Programmable Antigen‐Specific Immunity via Self‐Adjuvanting Nanovaccines Co‐Delivering Immune Modulators

Angewandte Chemie, EarlyView.
The self‐adjuvanting vaccine—comprising a covalent conjugate of antigen and adjuvant—was formulated into cationic lipid nanoparticles smaller than 100 nm to facilitate uptake by immune cells, with supplemental adjuvants incorporated to modulate immune responses.

Structural and mechanistic bases for resistance of the M66I capsid variant to lenacapavir

mBio
Lenacapavir (LEN) is the first-in-class viral capsid protein (CA) targeting antiretroviral for treating multi-drug-resistant HIV-1 infection. Clinical trials and cell culture experiments have identified resistance-associated mutations (RAMs) in the ...

Exposure to wild-type AAV drives distinct capsid immunity profiles in humans

Journal of Clinical Investigation, 2018
Recombinant adeno-associated virus (AAV) vectors have been broadly adopted as a gene delivery tool in clinical trials, owing to their high efficiency of transduction of several host tissues and their low immunogenicity. However, a considerable proportion
