Targeting the PGRN‐BMP Lysosomal Axis With NPs@PGRN Reverses Immunometabolic Dysfunction in Chronic Septic Arthritis

open access: yesAdvanced Science, EarlyView.
Chronic septic arthritis involves intracellular bacterial persistence and lipid‐immune crosstalk via the PGRN‐BMP lysosomal axis. A dual‐targeting nanoparticle system (NPs@PGRN) restores lysosomal bactericidal function, reduces bacterial burden, and reprograms macrophage immunity, offering a novel therapeutic strategy. ABSTRACT Chronic septic arthritis,

The New Nitric Oxide Donor, FOR 911B, Induces Relaxation in Isolated Rat Aorta Involving the NO/sGC/cGMP Pathway and K+ Channels

open access: yesReceptors
Background: Nitric oxide (NO) is a gaseous molecule considered to be a protagonist in the dilation of blood vessels, and its property and/or bioavailability are reduced in pathophysiological conditions such as cardiovascular diseases.

Effects of novel muscarinic M3 receptor ligand C1213 in pulmonary arterial hypertension models. [PDF]

open access: yes, 2016
Pulmonary hypertension (PH) is a complex disease comprising a pathologic remodeling and thickening of the pulmonary vessels causing an after load on the right heart ventricle that can result in ventricular failure. Triggered by oxidative stress, episodes

Heme‐NO Dilates Arteries via Mobilization of NO Moieties From an Intracellular NO Store Within Vascular Smooth Muscle Cells

open access: yesAdvanced Science, EarlyView.
Nitrosyl heme emerges as an extracellular nitrodilator that dilates arteries without crossing the cell membrane. Instead, heme‐NO mobilizes NO moieties from a preformed intracellular NO store within vascular smooth muscle, providing both functional and chemical evidence for the NANOS model, revealing a previously unrecognized mechanism of arterial ...

Hydrogen Sulfide-Induced Vasodilation: The Involvement of Vascular Potassium Channels

open access: yesFrontiers in Pharmacology, 2022
Hydrogen sulfide (H2S) has been highlighted as an important gasotransmitter in mammals. A growing number of studies have indicated that H2S plays a key role in the pathophysiology of vascular diseases and physiological vascular homeostasis. Alteration in

A Radioresistant‐Tumor‐Targeted Nanoparticle for X‐Ray‐Controlled Nitric Oxide Release to Potentiate Radiotherapy

open access: yesAdvanced Science, EarlyView.
The PBTN targets GRP78 and, upon X‐ray irradiation, generates ONOO− to induce immunogenic cell death, thereby activating CD8+ T cells and establishing a systemic antitumor immune response. ABSTRACT Nitric oxide (NO) treated radioresistant tumors by relieving hypoxia and blocking DNA repair, but its nonselective toxicity has precluded therapeutic use ...

Vasodilation increases pulse pressure variation, mimicking hypovolemic status in rabbits

open access: yesClinics, 2010
OBJECTIVE: To test the hypothesis that pulse pressure respiratory variation (PPV) amplification, observed in hypovolemia, can also be observed during sodium nitroprusside (SNP)-induced vasodilation.

The GPR18 Agonist PSB-KD-107 Exerts Endothelium-Dependent Vasorelaxant Effects

open access: yesPharmaceuticals, 2021
GPR18 is an orphan GPCR that is activated by the cannabinoid tetrahydrocannabinol (THC). Emerging evidence indicates its involvement in the control of cardiovascular functions, including heart rate, contractility, vascular tone, as well as blood pressure.
