SPRTN Ubiquitin Binding and DPC Proteolysis
2026-09-16
The bioRxiv study identifies a ubiquitin-binding domain within the N-terminal catalytic region of SPRTN and shows that ubiquitin-chain recognition strongly stimulates proteolysis of DNA-protein crosslinks. Its central finding is that polyubiquitination is not merely a recruitment mark: it provides a specificity signal that increases SPRTN proteolytic activation by approximately 67-fold relative to unmodified crosslinks.

Ferritin Hybrid Vaccine for Influenza and SARS-CoV-2
2026-09-16
This study developed a ferritin-based hybrid protein particle that co-displays the influenza A M2e antigen and tandem SARS-CoV-2 S-protein epitopes. Production in Escherichia coli generated a multivalent particle with stronger antibody responses and functional antiviral activity than corresponding antigen-only or single-antigen ferritin constructs.

Ionizable and PEGylated Lipids in mRNA-LNP Potency
2026-09-15
This 2025 Journal of Controlled Release study shows that commonly used ionizable and PEGylated lipids can produce lipid nanoparticles with similar physical quality attributes but markedly different mRNA expression. Its combined HEK293-cell and mouse experiments demonstrate why particle size, dispersity, and encapsulation efficiency alone are insufficient predictors of in vivo potency.

Cy5 Hydrazide: A Quantitative Carbonyl Assay Framework
2026-09-15
Cy5 hydrazide enables sensitive carbonyl-reactive fluorescent dye workflows for distinguishing biomolecular oxidation from nanoparticle behavior. This article presents an interpretation-first framework for protein carbonylation labeling, controls, normalization, and translation of far-red fluorescence data.

CART–RNA Nanoparticles: Structure and Morphology
2026-09-14
The reference study defines how degradable Charge-Altering Releasable Transporter (CART) amphiphiles organize RNA into coacervate nanoparticles with disordered bicontinuous interiors. By combining cryogenic microscopy with small-angle neutron and X-ray scattering, it connects polymer architecture and RNA cargo identity to internal domain spacing, offering structural guidance for polymer-based RNA delivery design.

From ARCA mRNA to Immune Architecture
2026-09-11
Spleen-targeted neoantigen vaccination shows how mRNA chemistry, delivery biology, and immune-cell organization must be engineered together. This thought-leadership guide translates those findings into practical synthesis, validation, and development strategies using ARCA-capped, polyadenylated mRNA.

Carboxylesterase and Mitochondrial H2O2 Assays
2026-09-11
The reference study shows that carboxylesterase can convert Amplex Red to resorufin without hydrogen peroxide, horseradish peroxidase, or oxygen, creating a major confounder in mitochondrial ROS measurements. Its controls and proposed corrections provide a practical framework for distinguishing genuine H2O2 release from matrix-driven probe conversion.

Axon Trafficking Limits TIA1 Aggregation
2026-09-10
This bioRxiv preprint identifies Annexin A7 (ANXA7) as an adaptor that connects TIA1-containing ribonucleoprotein complexes to cytoplasmic dynein for retrograde axonal transport. The study proposes that persistent calcium elevation or ANXA7 loss uncouples this pathway, allowing pathological TIA1 aggregation and contributing to axonopathy and neurodegeneration.
