Innovative Approach Reveals How Receptors Control G Protein State Equilibria

open access: yesAdvanced Science, EarlyView.
Using conformational specific trFRET biosensors of the Gi protein (depicted at the bottom), the authors show that receptor activation can not only release GDP from the inactive G protein, but can also release GTP from the activated G protein, leading to the reformation of the RG ternary complex.

Versatile Microgel Platform for Intervertebral Disc Degeneration Therapy: Targeting Pericyte‐Mediated Fibrosis and Protecting Nucleus Pulposus Cells

open access: yesAdvanced Science, EarlyView.
The engineered MMS@TRP microgel enables targeted, acid‐responsive delivery of a miR‐21 inhibitor to pericytes. It effectively suppresses disc fibrosis by inhibiting TGF‐β signaling while protecting nucleus pulposus cells via sustained, antioxidant tannic acid release.

Soil pH Amelioration Synergizes Carbon Accrual with Yield Gains Under Organic Substitution

open access: yesAdvanced Science, EarlyView.
Soil pH shifts towards neutrality in both acidic and alkaline soils under organic substitution. A global synthesis links pH amelioration to soil organic carbon accrual through enhanced microbial biomass after accounting for added organic carbon and its interaction with pH. This pH amelioration‐shared soil organic carbon accrual accounts for 5.1–8.6% of

PBRM1 Deficiency in Microglia Leads to Excessive Neurogenesis and Autism‐Like Behaviors via the CCL5‐CCR1/5‐β‐catenin Signaling Axis

open access: yesAdvanced Science, EarlyView.
Microglial PBRM1 deficiency drives excessive hippocampal neurogenesis by enhancing CCL5–CCR1/5 signaling, leading to autism‐like behaviors. A pro‐inflammatory IL1α+/TNFα+ microglial subset is identified as a key cellular contributor to this process. PBRM1 represses Ccl5 expression at the transcriptional level.

Determination of Gene‐Level Fitness Contributions Across the Mucin‐Utilization Network of Bacteroides thetaiotaomicron

open access: yesAdvanced Science, EarlyView.
Genome‐wide CRISPRi and RNA‐seq resolve how B. thetaiotaomicron converts host mucosal glycans into fitness. The study reveals a layered mucin‐utilization architecture in which capsular polysaccharides constrain surface access, extracellular CAZymes and peptidases show functional redundancy, and intracellular catabolic pathways create discrete metabolic

Orthogonal Light‐ and Enzyme‐Triggered and‐Gate Prodrugs for Senolytic Therapy

open access: yesAdvanced Science, EarlyView.
An orthogonal AND‐gate prodrug platform combines 390 nm near‐UV photocleavage with SA‐β‐gal activation to control payload release in senescent cells. Its modular architecture enables 4‐MU fluorescence, doxorubicin‐mediated cytotoxicity, and ARV‐771‐driven BRD4 degradation, supporting stimulus‐controlled senolytic design in cellular and organoid models.
