An intramuscular prime-intranasal boost strategy for mRNA-LNP vaccine induces mucosal immune response against SARS-CoV-2 in murine model

Journal of Translational Medicine
Background Mucosal immunity constitutes the primary defense against pathogens. Vaccination strategies aimed at inducing mucosal immunity are therefore crucial for preventing viral infections. Lipid nanoparticle (LNP) delivery systems enhance mRNA vaccine

A Robust Bio‐Supportive Hydrogel Patch for Full‐Thickness Repair of Gastroesophageal Defects

Advanced Science, EarlyView.
Gastroesophageal defect repair remains a formidable clinical challenge plagued by high leakage and life‐threatening complications. We develop a double‐disc, highly crystalline PVA‐based RBS hydrogel patch featuring suture‐free sealing, robust acid/enzyme resistance and mechanical durability.

Oral Recombinant Human Collagen III Protects Gastric Mucosa via G‐Quadruplex‐Mediated Activation of the Pla2g4a‐Prostaglandin Axis

Advanced Science, EarlyView.
Orally administered recombinant human type III collagen protects the gastric mucosa from ethanol‐induced injury by coordinating redox homeostasis, epithelial barrier repair, and arachidonic acid–prostaglandin metabolism. Gastric digestion releases the pentapeptide GPAEF, which interacts with the Pla2g4a promoter G‐quadruplex in a structure‐dependent ...

Gut Microbial Topology and Metabolic Signatures Associated With Colorectal Neoplasia

Advanced Science, EarlyView.
The gut microbiota organizes into two robust association patterns linked to colorectal neoplasia risk. Topological shifts in microbial networks are associated with metabolite alterations and may shape host responses during disease development. ABSTRACT Alterations of gut microbial communities impact health.

An Adenoviral‐Vectored Tp0326 Vaccine Elicits Robust Functional Antibodies to Prevent Treponema pallidum Dissemination in a Rabbit Model

Advanced Science, EarlyView.
Vaccination promotes cellular infiltration into primary lesions and effectively inhibits T. pallidum dissemination to distal organs. Notably, transfer of lesion tissue from immunized animals fails to establish infection in naive recipients, confirming specific protective immunity.

A Postbiotic‐Inducing Ganoderma applanatum Polysaccharide Repairs the Intestinal Barrier via a Phocaeicola vulgatus ‐ Tridecylic Acid Axis

Advanced Science, EarlyView.
This study identifies GAP2, a bioactive polysaccharide fraction derived from Ganoderma applanatum, as a postbiotic inducer that repairs intestinal barrier damage in a gut microbiota‐dependent manner. GAP2 enriches Phocaeicola vulgatus, which degrades GAP2 and promotes tridecylic acid production, triggering Rho/CDC42 signaling and tight‐junction ...

Intermittent Fasting Reduces Taurine Availability and Promotes Antitumor Immunity Through PERK Attenuation‐Associated Paraptosis‐Like Cell Death in Colorectal Cancer

Advanced Science, EarlyView.
This study identifies reduced taurine availability as a mediator of intermittent fasting in colorectal cancer and shows that taurine interacts with GRP78 to maintain PERK abundance post‐transcriptionally. It further shows that taurine depletion destabilizes PERK, induces immunogenic paraptosis, remodels the tumor microenvironment toward a CD8+ T cell ...
