Benzene with Alkyl Chains Is a Universal Scaffold for Multivalent Virucidal Antivirals

Francesco Stellacci, Paulo Henrique Jacob Silva, Lixia Wei, Matteo Gasbarri, Yong Zhu, Heyun Wang

Most viruses start their invasion by binding to glycoproteins' moieties on the cell surface (heparan sulfate proteoglycans [HSPG] or sialic acid [SA]). Antivirals mimicking these moieties multivalently are known as broad-spectrum multivalent entry inhibito ...

A Synthetic Multivalent Lipopeptide Derived from Pam3CSK4 with Irreversible Influenza Inhibition and Immuno-Stimulating Effects

Armand Kurum, Francesco Stellacci, Quy Ong Khac, Bruno Emanuel Ferreira De Sousa Correia, Pablo Gainza Cirauqui, Li Tang, Lixia Wei, Yong Zhu, Francesca Olgiati

The activation of the host adaptive immune system is crucial for eliminating viruses. However, influenza infection often suppresses the innate immune response that precedes adaptive immunity, and the adaptive immune responses are typically delayed. Dendrit ...

Influence of structural dynamics on cell uptake investigated with single-chain polymeric nanoparticles

Francesco Stellacci, Arthur Eliot Bouchez, Lixia Wei, Suiyang Liao

Most nanoparticles' parameters affect their interactions with cells. To date, all the parameters studied are basically static (e.g., size, shape, ligands, and charge). This is unfortunate, because proteins have struc-tural dynamics that most nanoparticles ...

Protein Engineering for Personalized therapy and diagnosis

Lixia Wei

Protein Engineering, especially protein post-translational modification (PTM), ex-tends proteomes in a more complex way than one can expect from analysis of their encod-ing genomes. It can activate or deactivate certain catalytic functions, add new desired ...

Control and Characterization of the Compactness of Single-Chain Nanoparticles

Francesco Stellacci, Luciano Andres Abriata, Lixia Wei, Suiyang Liao

Polymers when self-cross-linked into single-chain nanoparticles bear some resemblance to folded proteins; yet proteins have clear energy landscapes that determine precisely folded structures, while single-chain polymer nanoparticles (SCNPs) have more undef ...
