Summary: The study suggests a correlation between endothelial cell aging and altered expression of lncRNAs, which may impair endothelial regenerative capacity and enhance inflammatory phenotypes.

Summary: In an investigation into signaling triggered by aging and hyperglycemia, researchers found that NADPH Oxidase (NOX) plays a crucial role in driving cell damage, inflammation, and cellular senescence. Inhibiting NOX1 can reverse age-related impairments in blood flow and angiogenesis, as well as disrupt proinflammatory signaling associated with senescence. Targeting the NOX1-SASP signaling axis is predicted to be an effective strategy for mitigating vascular and organ system senescence.

Summary: This study revealed that aging has an additive effect on insulin- and IGF-1-mediated endothelial dysfunction in SHRs, partly due to reduced NO production and antioxidant deficiency.

Summary: The study aimed to investigate the effect of estrogen replacement therapy in aged female mice, showing that estrogen can reduce arterial pressure, improve endothelial function, but cannot improve vascular and cardiac fibrosis.

Summary: This article outlines the functions of RhoA in the cardiovascular system and its corresponding cellular responses. RhoA plays a crucial role in cardiac remodeling through regulating actin stress fiber dynamics and cytoskeleton formation. However, its underlying mechanisms remain unclear and require further investigation.

Summary: Advanced age is associated with arterial dysfunction and a decrease in glycocalyx, which may be linked to reduced synthesis of high molecular weight-hyaluronan (HMW-HA). Manipulation of glycocalyx properties can alter arterial function. The study demonstrates that reducing hyaluronan synthase 2 (Has2) leads to a decrease in glycocalyx thickness and induces arterial dysfunction. However, glycocalyx-targeted therapy can enhance glycocalyx properties and improve arterial function in old mice.

Immunology

Summary: Recent studies have shown that the structural changes of secondary lymphoid organs (SLOs) with age are correlated with diminishing immune responses. The aged tissue microenvironment can contribute to decreased immune function, unrelated to intrinsic changes in hematopoietic cells with age. Stromal cells play an important role in maintaining immune homeostasis, but their roles in SLO maintenance with advanced age are still unknown.

Summary: This review explores the impact of aging on arterial stiffening, highlighting the lack of effective therapeutic strategies. It discusses common techniques to measure stiffness, observed stiffness values in atherosclerosis and aging, as well as the endothelial response to stiffening and potential interventions. Future research on endothelial contribution to stiffness-related cardiovascular disease may offer new targets for intervention in atherosclerosis.

Summary: The arterial wall is organized into layers, with each layer playing a specific role in clearing substances from the blood. The endothelium acts as a barrier, while the media layer is involved in taking up molecules and particles. The outer layers, including the adventitia and perivascular tissue, also contribute to the clearance functions. These clearance functions are essential for maintaining arterial health but can also contribute to pathologies.

Summary: Astragalus polysaccharides (APS) have a protective effect against senescence and mitochondrial dysfunction in rat aortic endothelial cells (RAECs), and this effect is mediated by modulating NCLX to reduce inflammasome activation and senescence.

Summary: Aging of the arteries is characterized by increased stiffness and impaired dilation, which can be ameliorated by deleting T cells. In this study, thymectomized mice showed similar T cell changes and arterial dysfunction as old mice, indicating that an aged-like T cell phenotype alone is sufficient to induce arterial dysfunction in young mice.

Summary: The study revealed an age-related increase in APP expression in vascular endothelium, which is believed to be an adaptive response aimed at protecting and maintaining eNOS function. Endothelial dysfunction was exacerbated in aged eAPP(-/-) mice compared to age-matched WT mice, suggesting a crucial role of APP in controlling endothelial function during aging.

Summary: The vascular endothelium is crucial in embryogenesis and aging, and it lines the blood vessels as a cell monolayer. It is recognized by the immune system as part of the body, so any abnormality in the endothelium exposes tissues to the immune system, leading to inflammation and vascular diseases like atherosclerosis. The endothelium's secretory role allows it to release vasoconstrictors, vasorelaxants, and cardio-modulatory factors that maintain proper circulatory system functioning. Adhesion molecules play a significant role in cardiovascular physiology and pathology by providing a seal for the monolayer.

Summary: Pin1 functions as a key regulator of vascular homeostasis by modulating nitric oxide bioavailability and influencing various pathways involved in vascular diseases. Understanding the role of Pin1 in vascular endothelium could provide new insights for potential therapeutic strategies in vascular pathologies and neurodegenerative diseases.
