Extracellular vesicles as human therapeutics: A scoping review of the literature.

Extracellular vesicles (EVs) are released by all cells and contribute to cell-to-cell communication. The capacity of EVs to target specific cells and to efficiently deliver a composite profile of functional molecules have led researchers around the world to hypothesize their potential as therapeutics. While studies of EV treatment in animal models are numerous, their actual clinical benefit in humans has more slowly started to be tested.

Organ-specific biological clocks: Ageotyping for personalized anti-aging medicine.

Aging is a complex multidimensional, progressive remodeling process affecting multiple organ systems. While many studies have focused on studying aging across multiple organs, assessment of the contribution of individual organs to overall aging processes is a cutting-edge issue. An organ's biological age might influence the aging of other organs, revealing a multiorgan aging network.

Microplastics and Nanoplastics in Atheromas and Cardiovascular Events.

Background: Microplastics and nanoplastics (MNPs) are emerging as a potential risk factor for cardiovascular disease in preclinical studies. Direct evidence that this risk extends to humans is lacking.

Methods: We conducted a prospective, multicenter, observational study involving patients who were undergoing carotid endarterectomy for asymptomatic carotid artery disease.

The legacy effect of hyperglycemia and early use of SGLT-2 inhibitors: a cohort study with newly-diagnosed people with type 2 diabetes.

Background: A delay in reaching HbA1c targets in patients with newly-diagnosed type 2 diabetes (T2D) is associated with an increased long-term risk of developing cardiovascular diseases (CVD), a phenomenon referred to as legacy effect. Whether an early introduction of glucose-lowering drugs with proven benefit on CVD can attenuate this phenomenon is unknown.

Methods: Using data derived from a large Italian clinical registry, .

Evidence of an anti-inflammatory effect of PCSK9 inhibitors within the human atherosclerotic plaque.

Background And Aims: Preclinical evidence suggests that proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors hold anti-inflammatory properties independently of their ability to lower LDL-cholesterol (C). However, whether PCSK9 inhibitors exert anti-inflammatory effects within the atherosclerotic plaque in humans is unknown. We explored the impact of PCSK9 inhibitors, used as monotherapy, compared with other lipid-lowering drugs (oLLD) on the expression of inflammatory markers within the plaque, assessing also the subsequent incidence of cardiovascular events.

Weight variability and diabetes complications.

Body weight is a recognized risk factor for cardiovascular diseases (CVD). More recently, weight variability, i.e.

SIRT3 mediates the effects of PCSK9 inhibitors on inflammation, autophagy, and oxidative stress in endothelial cells.

: Proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors (i) are a class of lipid-lowering drugs suggested to hold a plethora of beneficial effects independent of their LDL cholesterol-lowering properties. However, the mechanism underlying such observations is debated. : Human aortic endothelial cells (TeloHAEC) were pre-treated with 100 µg/mL of the PCSK9i evolocumab and then exposed to 20 ng/mL of IL-6, a major driver of cardiovascular diseases (CVD), in both naïve state and after siRNA-mediated suppression of the NAD-dependent deacetylase sirtuin-3 (SIRT3).

Repurposing SGLT-2 Inhibitors to Target Aging: Available Evidence and Molecular Mechanisms.

Caloric restriction promotes longevity in multiple animal models. Compounds modulating nutrient-sensing pathways have been suggested to reproduce part of the beneficial effect of caloric restriction on aging. However, none of the commonly studied caloric restriction mimetics actually produce a decrease in calories.
