Pterostilbene protects against lipopolysaccharide-induced inflammation and blood-brain barrier disruption in immortalized brain endothelial cell lines in vitro.

Brain microvascular endothelial cells are connected by tight junction (TJ) proteins and interacted by adhesion molecules, which participate in the selective permeability of the blood-brain barrier (BBB). The disruption of BBB is associated with the progression of cerebral diseases. Pterostilbene is a natural compound found in blueberries and grapes with a wide range of biological activities, including anti-inflammatory, antioxidant, and anti-diabetic effects.

Oxidative stress and apoptosis are highly engaged in development of diabetic nephropathy (DN). In monotherapy, dapagliflozin and pioglitazone positively modulate target organ damage even independently of their hypoglycaemic effect. This study evaluated whether a simultaneous PPARγ activation and SGLT cotransporter inhibition offer superior protection against DN-related oxidative and apoptotic processes in a T1DM rat model.

Glomerular endothelial cells (GECs) are pivotal in developing glomerular sclerosis disorders. The advancement of focal segmental glomerulosclerosis (FSGS) is intimately tied to disruptions in lipid metabolism. Sphingosine-1-phosphate (S1P), a molecule transported by high-density lipoproteins (HDL), exhibits protective effects on vascular endothelial cells by upregulating phosphorylated endothelial nitric oxide synthase (p-eNOS) and enhancing nitric oxide (NO) production.

Clinical Institute of Medical and Chemical Laboratory Diagnostics, Medical University of Graz, 8036, Graz, Austria.
Early depressive symptoms within the first days after acute myocardial infarction (AMI) are mainly manifested with performance parameters (lack of energy, concentration difficulties, reduction in physical functioning). Homoarginine (hArg), a non-proteinogenic amino acid, might increase the availability of nitric oxide (NO). NO controls vasodilatation, blood flow, mitochondrial respiration and improves performance.

Cancer photoimmunotherapy represents an intelligent and highly efficient therapeutic approach that harnesses the photothermal effect to precisely target and ablate tumor tissues, while simultaneously modulating the immune system to achieve tumor elimination. The integration of multifunctional therapeutic modalities for combined photoimmunotherapy requires advanced drug delivery systems. However, the design of a single nanoagent capable of serving as a multifunctional nanophotosensitizer remains a significant challenge.
