A Dynamic Gate Enables Regioselective Hydroxylation of Free Arginine by a Non‐Canonical Heme Enzyme

open access: yesAdvanced Science, EarlyView.
The YqcI/YcgG enzyme AglA employs a unique “sandwich” fold and a dynamic gating mechanism to selectively hydroxylate AMPn‐Arg at Nε. Site‐directed mutations reprogram regioselectivity or enable activity on free arginine by altering hydrogen‐bond networks, precisely positioning substrates.

Dual Disruption of the Immune Cytokine Spätzle Facilitates Fungal Infection of Diverse Insect Hosts

open access: yesAdvanced Science, EarlyView.
The Toll pathway is essential for insect defense against fungal pathogens. This works reports that fungal parasites employ two divergent virulent effectors to target the Toll receptor ligand Spätzle: a metalloprotease degrading it and a hairpin‐like effector hijacking it to block signal transduction. This dual strategy enables the fungus to kill a wide

Immunomodulatory Hydrogel Coating with SeNPs and Lithium Silicate Synergistically Promotes Osseointegration and Prevents Infection on Titanium Implants

open access: yesAdvanced Science, EarlyView.
This study introduces a multifunctional hydrogel coating (Lap‐CMCSMA/GelMA@SeNPs) that scavenges ROS, modulates immune responses, and shows strong antibacterial activity. It effectively restores the peri‐implant microenvironment. The coating exhibits excellent biocompatibility and promotes osteogenic differentiation.

Fibrates Inhibit PLTP‐induced M2 Macrophage Infiltration and Increase the Sensitivity of Hepatocellular Carcinoma to ICIs

open access: yesAdvanced Science, EarlyView.
Phospholipid transfer protein(PLTP) plays a critical role in forming a complex with kinase A (AURKA) and P65. This interaction facilitates phosphorylation of P65 at Ser536, leading to the activation of the NF‐κB signaling pathway. Ultimately, this leads to the upregulation of downstream cytokines, including IL‐6, IL‐8, and CSF‐1, which promotes M2 ...
