A Solution to Chemical Pseudaminylation via Development of a Bimodal Glycosyl Donor to Enable Highly Stereocontrolled α- and β-Glycosylation

open access: yes, 2019
Bacterial pseudaminic acids (Pse) are present on the surface of many pathogenic bacteria. Herein, we report a robust methodology for the stereocontrolled chemical glycosylation of pseudaminic acid to afford both α- (axial) and β- (equatorial) glycosides ...

Encapsulated Leptin‐Producing Cells Facilitate Entrainment of Circadian Rhythms in Rodents and Nonhuman Primates

open access: yesAdvanced Science, EarlyView.
A clinically translatable cell line can be engineered to produce leptin, encapsulated in biomaterial and safely implanted to produce and deliver the metabolic regulating protein within the body. Implantation of these encapsulated cells decreases the time it takes for mice and non‐human primates to adjust to circadian disruptions similar to those ...

Switching Spike Plasticity Shapes ACE2 Engagement Across SARS‐CoV‐2 Variants

open access: yesAdvanced Science, EarlyView.
Conformational plasticity governs SARS‐CoV‐2 spike function and ACE2 recognition. Using high‐speed AFM and single‐molecule force spectroscopy, we analyzed the ancestral spike and nine variants, revealing progressive rigidification from Delta, variable plasticity in Omicron sublineages, and JN.1 compaction.

A Synthetic Platform for Antibody Junctional Diversification Beyond Natural Constraints

open access: yesAdvanced Science, EarlyView.
ARESEC is a synthetic platform that reconstructs functional V(D)J recombination in HEK293T cells. By introducing RSS elements and co‐expressing RAG1/2 and TdT across all three antibody CDRs, it enables programmable junctional diversification and direct generation of high‐affinity variants targeting PD‐1/PD‐L1, overcoming the evolutionary constraints of

Characterization of the glycosylation and signal peptide sequences within the vaccinia virus m2 protein and influence on ERK1/2 and NF-kB activation [PDF]

open access: yes, 2010
Activation of the NF-κB transcription factor during cellular infection establishes an anti-viral state via upregulation of proinflammatory proteins. Wild-type vaccinia virus (VV) strains subvert the immune response by expressing proteins that interfere ...

Stereocontrolled Synthesis of α-C-Galactosamine Derivatives via Chelation-Controlled C-Glycosylation

open access: yes, 2016
The samarium diiodide-promoted reduction of 2-deoxy-2-acetamidogalactosyl pyridyl sulfone α-5 with ketones or aldehydes under Barbier conditions led unexpectedly to the stereoselective synthesis of α-C-galactosamine derivatives in good yields.

An Engineered HR1‐Stem Helix‐HR2 Trimeric Platform for Developing Broad‐Spectrum Coronavirus Vaccines

open access: yesAdvanced Science, EarlyView.
Sun et al. report a self‐assembling trimeric subunit vaccine platform termed RHS, which integrates the JN.1 receptor‐binding domain (RBD) with the heptad repeat 1 (HR1), stem helix (SH), and heptad repeat 2 (HR2) regions. The SARS‐CoV‐2 RHS vaccine elicits variant‐reactive RBD‐specific antibodies and cross‐reactive SH‐specific antibodies against ...

An RNA‐Binding Protein RBMS1 Promotes Endothelial Cell Autophagy to Maintain Vascular Homeostasis and Suppress Deep Vein Thrombosis

open access: yesAdvanced Science, EarlyView.
RBMS1, an RNA‐binding protein, restores vascular endothelial homeostasis by enhancing ATG3‐mediated autophagy, thereby attenuating thrombus formation and suggesting a potential avenue for further therapeutic exploration in DVT. ABSTRACT Deep vein thrombosis (DVT) is a prevalent vascular disorder characterized by aberrant coagulation within the deep ...

A Novel model for Mucin-type O-glycosylation sites Prediction

open access: yes, 2010
Glycosylation, one of the most common protein post-translational modifications, is involved in a variety of important biological processes, including protein stability, solubility, secretion of signal, extracellular recognition, regulation of ...
