"answer": "Recent discoveries regarding the impact of systemic factors, such as circulating microvesicles, on aging phenotypes include the following: 1. The importance of progeronic (aging-promoting) and antigeronic (aging-delaying) circulating factors in the development of vascular aging phenotypes has been discussed. This highlights the role of systemic factors in contributing to age-related vascular pathologies and suggests potential interventions to prevent or delay these conditions by targeting fundamental cellular and molecular aging processes [1]. 2. Studies using heterochronic parabiosis, which involves connecting the circulatory systems of young and aged mice, have demonstrated the impact of circulating factors on aging phenotypes. This research provides initial evidence that circulating factors can influence cerebromicrovascular density, which typically declines with advanced age [3]. These findings underscore the significant role that systemic factors, including circulating microvesicles, play in influencing aging phenotypes, particularly in the context of vascular aging and potential rejuvenation strategies.",
