Project Summary The proposed study will investigate the role of endothelial progenitor cells in neurovascular dysfunction and cognitive decline among older adults with low levels of traditional vascular risk and normal baseline cognitive function. Specifically, we will study whether changes in endothelial progenitor cell proliferation and senescence are predictive of cognitive decline, vascular brain lesions and structural and functional brain connectivity. We will also study secretory factors from endothelial progenitor cell cultures to better understand how progenitor cell function relates to neurovascular dysfunction, brain injury and cognitive decline.

项目摘要 这项研究将探讨内皮祖细胞在神经血管功能障碍中的作用， 具有低水平传统血管风险和正常基线认知能力的老年人的认知能力下降 功能具体来说，我们将研究内皮祖细胞增殖和衰老的变化是否 是认知能力下降、脑血管病变以及脑结构和功能连通性的预测指标。我们将 我还研究了内皮祖细胞培养物中的分泌因子，以更好地了解祖细胞 功能障碍与神经血管功能障碍、脑损伤和认知能力下降有关。
