Pre‐Encoded IFN‐I Sensitivity Exacerbates Memory T Cell Senescence in Solid Tumors
Type I interferon (IFN‐I) signaling promotes p21‐dependent cell cycle arrest in senescent tumor‐specific memory T cells, resulting in poor proliferative responses and solid tumor regression during cancer vaccination. Conversely, IFNα/β receptor blockade reinvigorates T cell proliferation to regress solid tumors and is more effective with increasing ...

Engineering a Virus‐Derived X Family DNA Polymerase FvPolX for de novo DNA Synthesis
In this study, a Faustovirus‐derived polymerase (FvPolX) is engineered based on structural and sequence analysis of PolX enzymes. The optimal mutants demonstrate substantially enhanced catalytic activity toward dNTPs and 3′‐ONH2‐dNTPs compared to the wild‐type enzyme.

In anaerobic bacteria, tyrosine serves as an electron donor in the oxidative Stickland fermentation branch, generating p‐hydroxyphenylacetate, ATP and reduced ferredoxin for decarboxylation into p‐cresol. ABSTRACT The phenolic metabolite p‐cresol is a byproduct of tyrosine fermentation by certain strictly anaerobic bacteria, including the human gut ...

Severe Restriction of Glucose Import Enhances Recombinant Protein Production in Escherichia coli
Graphical Abstract and Lay Summary Producing recombinant proteins in Escherichia coli is often limited by the bacterium's tendency to consume glucose too rapidly. This excessive glucose uptake causes overflow metabolism, leading to the accumulation of acetate, a byproduct that can reduce cellular performance and protein production.

ABSTRACT Yeast sugar transporters have highly evolved for preferential glucose transport, a significant roadblock for utilizing non‐glucose sugars in renewable feedstocks such as lignocellulosic biomass. To enable simultaneous transport of multiple sugars, native hexose transporters were replaced by SWEET7p from Arabidopsis thaliana in engineered ...

Genetically Programmed Control of Overflow Metabolism
ABSTRACT Overflow metabolism is a highly undesirable phenomenon that occurs in virtually all cell factories. Although several schemes have been applied to avoid overflow metabolism, this problem remains far from being solved. In this study, a genetic sensor for detecting overflow metabolism was designed, and its substrate specificity and reversibility ...

Salt‐Driven Silk Fibroin Assembly for Solvent‐Free Multienzyme Co‐Immobilization
Salt‐induced silk fibroin assembly enables solvent‐free co‐immobilization of redox enzyme cascades in fully aqueous media without covalent modification. The protein matrix provides high operational stability and modulates cofactor accessibility, enhancing functional coupling within the confined microenvironment.

JN.1 vaccination induced strong, cross‐reactive CD4 and CD8 T‐cell responses and markedly boosted neutralizing antibodies, especially against omicron variants. Influenza vaccine coadministration did not impair immunogenicity. Prior SARS‐CoV‐2 infection was associated with higher baseline and postvaccine neutralizing activity, while cellular responses ...

In this study, the heme content and enzymatic activity of the RhDypB mutant strain RhDypB‐R80 were enhanced through optimized heme uptake and pathway integration. This engineered host presents a promising platform for hemoprotein engineering and holds potential for applications in controlling mycotoxin contamination in food products.
