Biomimetic Nanomedicine for Senescence‐Modulated Immune Activation Enhances Immunotherapy Efficacy in Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
A multifunctional mPDZM nanoplatform is developed in this study. mPDZM integrates chemotherapy‐induced senescence, selective senolysis, and STING‐mediated immune activation. mPDZM effectively clears senescent tumor cells, remodels the tumor immune microenvironment, and enhances antitumor T‐cell responses.

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 ...

Chytridiomycosis of marine diatoms : the role of stress physiology and resistance in parasite-host recognition and accumulation of defense molecules [PDF]

open access: yes, 2017
Little is known about the role of chemotaxis in the location and attachment of chytrid zoospores to potential diatom hosts. Hypothesizing that environmental stress parameters affect parasite-host recognition, four chytrid-diatom tandem cultures ...
