Oral Bioinspired Peroxisome‐Engineered Probiotics for Modulating Gut Microbiota Homeostasis and Alleviating Cardiac Chemotherapy Toxicity

Advanced Science, EarlyView.
This study developed an oral bioinspired peroxisome‐engineered probiotic (BPEP) by anchoring lipid‐encapsulated ruthenium nanozymes onto Escherichia coli Nissle 1917, utilizing probiotics to deliver nanozymes to the intestinal barrier for reactive oxygen species/reactive nitrogen species elimination, tight junction restoration, and gut microbiota ...

Time‐Multiplexed Organic Electrochemical Transistor for Saliva‐Based Rapid Detection of Viral Proteins

Advanced Science, EarlyView.
A time‐multiplexed nanobody‐functionalized organic electrochemical transistor enables rapid and sensitive detection of three respiratory viral proteins from saliva. Sequentially addressed multi‐gate electrodes on a shared channel achieve around 1 fm detection within 15 min without sample preprocessing. Clinical validation demonstrates high specificity,

Redox‐Dependent Chaperoning of GBF1 Condensates Regulates Seed Germination in Arabidopsis

Advanced Science, EarlyView.
In dormant seeds (low ROS), GBF1 forms liquid condensates to repress the germination gene CathB3, and the chaperone GIP1 maintains condensate liquidity and repressive activity. Upon imbibition (high ROS), ROS oxidize GIP1 during germination, impairing its chaperone function.

Time-resolved measurements of sugar-binding-induced conformational changes in the melibiose permease from Escherichia coli

, 2008
The melibiose permease (MelB) of E.coli functions as a secondary-active symporter by using the electrochemical H+, Na+, or Li+ gradient to accumulate, e.g., melibiose [review in Pourcher et al. 1990a].

Enhancing CAR‐T Cell Efficacy in Solid Tumors by Inhibiting CCL5/VEGF‐Mediated Angiogenesis

Advanced Science, EarlyView.
This study reveals that CAR‐T cells in solid tumors produce CCL5, which paradoxically induces VEGF and angiogenesis to promote tumor growth. Blocking CCL5/VEGF signaling—through gene knockout, or the CCR5 inhibitor maraviroc—significantly enhances the antitumor efficacy of CAR‑T therapy (the diagram was created in Biorender).

A Chirality‐Converted Bacteriolytic Dodecapeptide Regulates Vibrio‐Induced Polymicrobial Infection and Ameliorates Invasion‐Associated Gut Microbiota Disequilibrium

Advanced Science, EarlyView.
Multidrug‐resistant Vibrio infections are rising rapidly and threaten coastal populations worldwide. This study introduces D‐zp37, a chirality‐engineered antimicrobial peptide with exceptional potency against resistant Vibrio species. D‐zp37 kills planktonic cells, blocks mixed‐species biofilms, disrupts essential bacterial stress responses, and shows ...

The BnTFL1‐BnJAM3‐BnSWEETs Module Orchestrates Seed Storage Reserve Accumulation in Brassica napus

Advanced Science, EarlyView.
BnaC03.TFL1 and BnaA01.JAM3 form a complex that facilitates the transport of soluble sugars from the seed coat to the embryo by directly activating the expression of BnSWEETs. Furthermore, BnaC03.TFL1 and BnaA01.JAM3 work cooperatively to promote soluble sugar and oil production while suppressing protein deposition.
