Subacute administration of cilostazol modulates PLC-γ/PKC-α/p38/NF-kB pathway and plays vascular protective effects through eNOS activation in early stages of atherosclerosis development.

Aims: Hypercholesterolemia is an important risk factor for development of cardiovascular disturbances, such as atherosclerosis, and its treatment remains challenging in modern medicine. Cilostazol is a selective inhibitor of phosphodiesterase 3 clinically prescribed for intermittent claudication treatment. Due to its pleiotropic properties, such as lipid lowering, anti-inflammatory, and antioxidant effects, the therapeutic repurposing of cilostazol has become a strategic approach for atherosclerosis treatment.

Reviewing Atrial Fibrillation Pathophysiology from a Network Medicine Perspective: The Relevance of Structural Remodeling, Inflammation, and the Immune System.

Atrial fibrillation (AF) is the most common type of sustained arrhythmia. The numerous gaps concerning the knowledge of its mechanism make improving clinical management difficult. As omics technologies allow more comprehensive insight into biology and disease at a molecular level, bioinformatics encompasses valuable tools for studying systems biology, as well as combining and modeling multi-omics data and networks.

Impact of Brazil Nut (, H.B.K.) Supplementation on Body Composition, Blood Pressure, and the Vascular Reactivity of Wistar Rats When Submitted to a Hypersodium Diet.

Endothelium integrity is a key that maintains vascular homeostasis but it can suffer irreversible damage by blood pressure changes, reflecting an imbalance in the maintenance of vascular homeostasis. The aim of this study was to investigate the impact of Brazil nut (Bertholletia excelsa, H.B.

Could cilostazol be beneficial in COVID-19 treatment? Thinking about phosphodiesterase-3 as a therapeutic target.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19) that has emerged and rapidly spread across the world. The COVID-19 severity is associated to viral pneumonia with additional extrapulmonary complications. Hyperinflammation, dysfunctional immune response and hypercoagulability state are associated to poor prognosis.

Cilostazol exerts antiplatelet and anti-inflammatory effects through AMPK activation and NF-kB inhibition on hypercholesterolemic rats.

This work presents a model of rats fed a high-cholesterol diet, receiving a long-term oral administration of cilostazol, a PDE3-inhibitor. The aim of this study was to evaluate the molecular mechanisms by which cilostazol interferes with platelets signaling pathways to avoid atherosclerosis early development. Male Wistar rats were divided into 3 groups: Control group received standard rat chow (C), hypercholesterolemic group (HCD), and HCD+CIL (cilostazol group) received hypercholesterolemic diet for 45 days.

Anti-atherogenic effects of a new thienylacylhydrazone derivative, LASSBio-788, in rats fed a hypercholesterolemic diet.

The compound LASSBio-788 (N-Allyl (2-thienylidene) 3,4-methylenedioxybenzoylhydrazine) is a thienylacylhydrazone derivative shown to have antiplatelet, vasodilatory, and anti-inflammatory properties in vitro. We hypothesize that LASSBio-788 may exert beneficial effects on atherosclerosis. Male wistar rats were divided into 4 groups: Control group received standard rat chow, hypercholesterolemic group (HC) and HC+788 (compound LASSBio-788 group) received hypercholesterolemic diet for 45 days.
