Conformational Snapshots of CydDC in a Native Lipid Bilayer Coupling Heme Transport to Antibiotic Resistance

Advanced Science, EarlyView.
Phylogenetic and biochemical analyses of the heme transporter CydDC reveal its functional conservation throughout bacterial evolution and demonstrate its unique asymmetric allosteric mechanism. Furthermore, impairment of CydDC function directly affects bacterial antibiotic resistance and likely compromises antibiotic efficacy through drug efflux.

Clinical trial simulation of antiviral drugs

Journal of Virology
Antiviral clinical trial simulation (CTS) is a type of mathematical modeling that couples viral- immune dynamics (VID) unique to each human viral pathogen, with mechanistic, pharmacokinetic (PK), and pharmacodynamic (PD) drug characteristics.

ZNF33B Promotes Japanese Encephalitis Virus Infection by Regulating the Stability of M6A‐Modified Trim25 to Control the Autophagy Process

Advanced Science, EarlyView.
Upon JEV infection, ZNF33B recruits METTL14 to stabilize the METTL3‐METTL14 m6A methyltransferase complex, leading to increased m6A modification of host transcripts, including Trim25 mRNA. ZNF33B selectively binds m6A‐modified sites on Trim25 mRNA and accelerates its decay, resulting in reduced TRIM25 protein abundance.

Preferential amplification of CD8 effector-T cells after transcutaneous application of an inactivated influenza vaccine: a randomized phase I trial

, 2010
Background: Current conventional vaccination approaches do not induce potent CD8 T-cell responses for fighting mostly variable viral diseases such as influenza, avian influenza viruses or HIV.

Antigen Spreading via Localized Administration Enhances Adoptive TCR‐T Cell Therapy in Pancreatic Cancer

Advanced Science, EarlyView.
Cancer vaccines face limitations in pancreatic cancer due to insufficient tumor antigens. This ionic liquid ILvax via local tumor delivery triggers robust cDC1‐dependent systemic anti‐tumor immunity. It boosts endogenous CD8+ T cells and optimizes adoptive TCR‐T function, providing a promising synergistic therapeutic strategy.

Defining the impact of flavivirus envelope protein glycosylation site mutations on sensitivity to broadly neutralizing antibodies

mBio
Antibodies targeting an envelope dimer epitope (EDE) cross-neutralize Zika virus (ZIKV) and dengue virus (DENV) and have thus inspired an epitope-focused vaccine design. There are two EDE antibody subclasses (EDE1, EDE2) distinguished by their dependence

Cholesterol Laundry of Cell Membrane and Fatty Liver by Detergent Liposomes to Improve Anti‐Cancer Drug Responsiveness of Patient Liver Tissues

Advanced Science, EarlyView.
Cholesterol‐enriched plasma membranes in hepatocellular carcinoma impede drug penetration. Cholesterol (+)‐liposomes act as membrane‐specific detergents, extracting cholesterol and reducing barrier function without cytotoxicity. Following endocytosis, cholesterol transfers from endosomes to liposomes and is metabolized in the ER.

Nanomaterials for Allergy Diagnosis and Treatment: Advances, Opportunities and Translational Challenges

Advanced Science, EarlyView.
Nanomaterials offer dual applications in allergy management. For diagnosis, nanomaterials enhance analytical sensitivity and improve detection in specific IgE and functional assays such as the basophil activation test (BAT). For allergen‐specific immunotherapy, nanomaterials enable allergen masking and controlled release, and effectively modulate the ...
