Structure‐Guided Engineering of a Promiscuous O‐Methyltransferase for a SAM Regeneration Biocatalysis Platform of Methylated Pharmaceuticals

open access: yesAdvanced Science, EarlyView.
A substrate promiscuous and regioselective O‐methyltransferase, SmOMT, is functionally and structurally characterized. A double mutant, SmOMTE152A/I306A, exhibited enhanced catalytic activity. By coupling this mutant with a mutant halide methyltransferase, AtHMTV140T, for SAM regeneration, a superior artificial fusion enzyme, AtHMTV140T‐L95‐SmOMTE152A ...

Synthesis of Bispecific Conjugates by ADP‐Ribosyl Cyclases

open access: yesAdvanced Science, EarlyView.
Genetic fusion of a CD38 enzymatic domain to antibody scaffolds allows site‐specific conjugation of small‐molecule ligands. Using this approach, a PSMA ligand DUPA is conjugated with an anti‐human CD3 Fab antibody. The resulting bispecific anti‐CD3‐DUPA conjugate facilitates recruitment and activation of cytotoxic T cells against PSMA‐expressing ...

An Enzyme‐Like Catalyzed Nanosheets for Redox Stress Oscillation Therapy Against Bacterial Infections

open access: yesAdvanced Science, EarlyView.
Bacterial biofilms form a physicochemical barrier. Their dense network structure and redox homeostasis confer high resistance to antimicrobial treatments and immune‐mediated killing and clearance. In this study, SnSe nanosheets with enzyme‐like properties and piezoelectric catalysis can oscillate to regulate bacterial redox homeostasis and improve the ...

Endogenous Amplification of Apoptosis via p53 Regulation using a Cascade Nanocatalytic Medicine

open access: yesAdvanced Science, EarlyView.
An engineered MOF nanomedicine (MAL) triggers cascade nanocatalysis in tumors, converting H2O2 and L‐Arg into cytotoxic peroxynitrite. This induces DNA damage, activates the p53 pathway, and amplifies mitochondrial apoptosis via the BAX/Bcl‐2/Caspase‐3 axis, effectively inhibiting colorectal cancer growth with high biocompatibility.

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

open access: yesAdvanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome
