Enhancing vaccine half-life as a novel strategy for improving immune response durability of subunit vaccines.

Vaccines are widely regarded as one of the most effective strategies for combating infectious diseases. However, significant challenges remain, such as insufficient antibody levels, limited protection against rapidly evolving variants, and poor immune durability, particularly in subunit vaccines, likely due to their short in vivo exposure. Recent advances in extending the half-life of protein therapeutics have shown promise in improving drug efficacy, yet whether increasing in vivo persistence can enhance the efficacy of subunit vaccines remains underexplored.

Genome-Wide Identification and Expression Analysis of Gene Family Members in Seashore Paspalum Under Salt Stress.

The gene family plays a crucial role in plant growth, development, and responses to biotic and abiotic stresses. , a warm-season turfgrass with exceptional salt tolerance, can be irrigated with seawater. However, the gene family in seashore paspalum remains poorly understood.

Metabolites in Serum Small Extracellular Vesicles Instead of Small Extracellular Vesicles-depleted Serum Have Better Diagnostic Value for Cancers at Early Stage.

Serum is one of the most commonly used biofluids for biomarker exploration. Some studies examine serum directly, while others focus on specific components like small extracellular vesicles (sEVs), which are lipid-bilayer encapsulated particles carrying a variety of molecular cargos. However, the diagnostic value of serum sEVs versus sEVs-depleted fractions (EV-free serum) for early cancer detection are unclear.

[Research progress of single-cell RNA sequencing in the immune microenvironment of spinal cord injury].

Spinal cord injury (SCI) represents a complex pathophysiological process involving the interaction of multiple cell types. Conventional sequencing methods can only detect the average gene expression level of the damaged local cell populations, which is difficult to reflect its heterogeneity. Therefore, new technologies are needed to reveal the intercellular heterogeneity and the complex intercellular interactions of the damaged lesions.

The SUMO (Singly Unoccupied Molecular Orbital)-LUMO (Lowest Unoccupied Molecular Orbital) Inversion Radicals.

Herein, SUMO-LUMO inversion (SLI) radicals - were designed by the combination of the tris(2,4,6-trichlorophenyl)methyl (TTM) radical and pyridinium derivatives (electron-withdrawing groups) for the first time. The energy of the LUMO lies below that of the SUMO, which deviated from the Aufbau principle as an alternative electronic configuration beyond the well-established SOMO-HOMO inversed system. Thus, for SLI radicals, the injection of one extra electron preferred to occupy the LUMO rather than the SUMO, giving diradicals, one of which had been fully confirmed by single crystal analysis, VT-NMR and VT-EPR experiments, as well as DFT calculations.
