Asymmetric Structure‐Driven Functional Synergy: A Multistimuli‐Activated Janus Nanomotor for Self‐Amplifying NO Cascade Therapy

Advanced Science, EarlyView.
The Janus nanomotors leverage an “asymmetric structure‐driven functional synergy” strategy to orchestrate spatiotemporally coordinated catalytic functions, in situ self‐amplifying NO generation, and deep tumor penetration, thereby enabling controllable, sustained, and uniform NO generation within the tumor microenvironment.

A Hepatocyte‐to‐Stellate Cell Axis Couples Alternate‐Day Fasting to Liver Fibrosis Resolution via ATG7 S‐Nitrosylation

Advanced Science, EarlyView.
Alternate‐day fasting suppresses mitochondrial complex II assembly via SDHAF4 to upregulate hepatocyte eNOS. The resulting nitric oxide S‐nitrosylates ATG7 at C184 in hepatic stellate cells, restraining autophagic flux and preventing their profibrotic activation.

Assembled Hyaluronic Acid Therapeutics for Targeting M1 Macrophages and Regulating Immune Homeostasis for Ulcerative Colitis Treatment

Advanced Science, EarlyView.
An orally administered, drug‐free hyaluronic acid nanoassembly, uhNAs‐OA, accumulates in the inflamed colon and is preferentially internalized by M1‐like macrophages via HA‐CD44 interactions. uhNAs‐OA scavenges excess ROS, suppresses NF‐κB signaling and remodels the colonic immune landscape, resulting in robust therapeutic efficacy in acute, chronic ...

Astrocytes Coordinate Neurovascular Coupling During Prolonged Sensory Demand via AQP4/TRPA1/BEST1/D‐Serine Signaling

Advanced Science, EarlyView.
Neuronal activation leads to astrocytic transient volume changes, activating transient receptor potential ankyrin 1 (TRPA1) channels, leading to Ca2+ influx. Activation of TRPA1 causes the release of D‐serine through BEST1. Finally, the augmented extracellular levels of D‐serine boost neuronal activity by binding GluN1‐containing NMDARs, leading to CBV

Nitric oxide as a mediator of inflammation?—You had better believe it

Mediators of Inflammation, 1995
Nitric oxide has enigmatic qualities in inflammation. In order to appreciate the precise contributions of nitric oxide to a pathophysiological process, one must account for enzyme source, coproduction of oxidants and antioxidant defences, time, rate of ...

Programmable Self‐Heating Microneedle Patch for on‐Demand Postprandial Glucose Management

Advanced Science, EarlyView.
A programmable self‐heating microneedle patch enables on‐demand, timed‐sequence insulin delivery via user‐triggered quadrant activation. Each activation generates localized heat that melts a phase‐change barrier, accelerating drug release. In diabetic rats, sequential quadrant activation counteracts four meal‐mimicking glucose spikes over 24 h without ...

ERα–PADI4–CXCL8 Axis Drives MDSC‐Mediated Immune Evasion in Anaplastic Thyroid Carcinoma

Advanced Science, EarlyView.
MAPK‐driven ligand‐independent ERα activation drives PADI4 transcription and translation. This enzyme then modifies CXCL8 chemokines through citrullination, generating a potent chemoattractant gradient specifically for myeloid‐derived suppressor cells.

Bioenergetic Materials for Tissue Regeneration: Modulating Metabolism to Promote Cellular Anabolism

Advanced Science, EarlyView.
Bioenergetic materials (BEMs) modulate cellular metabolism to promote tissue regeneration. Their principal mechanisms of action include metabolic substrate supplementation, metabolic enzyme modulation, organelle transfer, electrical current regulation, redox homeostasis modulation, and oxygen tension modulation.

molecular docking, DFT, and toxicity studies of potential inhibitors derived from against human inducible nitric oxide synthase

Journal of Chemical Research
Inducible nitric oxide synthase is known as a potential biological target that plays a crucial role in regulating the release of nitric oxide and is responsible for the amount of nitric oxide released during the inflammation process.

Molecular Signatures of HIV‐Induced Neuroinflammation and Neurodegeneration in Human Cerebral Organoids: Identification of Therapeutic Targets for NeuroHIV

Advanced Science, EarlyView.
HIV preferentially infects microglia, activating IL‐17A‐driven IFN‐γ/STAT1, CEBPB, and NF‐κB signaling that converges with cGAS‐STING and Notch–NEURL1 pathways, promoting neuroinflammation, mitochondrial dysfunction, and synaptic impairment. cART suppresses viral replication, attenuates inflammatory signaling, and at least partially restores ...
