SYMPATHETIC NERVOUS SYSTEM REGULATION OF CELL ADHESION

该子项目是利用该技术的众多研究子项目之一 资源由 NIH/NCRR 资助的中心拨款提供。子项目及 研究者 (PI) 可能已从 NIH 的另一个来源获得主要资金， 因此可以在其他 CRISP 条目中表示。列出的机构是 对于中心来说，它不一定是研究者的机构。 我们将研究 12 周运动干预和 12 周运动加饮食干预对 150 名目前未服用抗高血压药物的高血压（血压 >140/90 mm Hg 但 <179/109 mm Hg）和高血压前期（血压 >120/80 mm Hg 但<140/90 mm Hg）患者的炎症和细胞粘附的影响。在干预之前和之后，我们将评估静息和压力引起的（精神应激源和跑步机运动测试）CRP、IL-6、TNF-α、sICAM-1、sE-选择素循环水平的变化、白细胞上β2-整合素亚基CD11a和CD11b的表达、白细胞活化（伪足形成）和外周血单核细胞（PBMC）趋化性。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. We will examine the effects of a 12-week exercise intervention and a 12-week exercise plus diet intervention on inflammation and cell adhesion in 150 patients with hypertension (blood pressure >140/90 mm Hg but <179/109 mm Hg) and prehypertensive (blood pressure >120/80 mm Hg but <140/90 mm Hg) who are currently not on anti-hypertensive medication. Prior to and following the interventions, we will assess resting and stress-induced (mental stressor and treadmill exercise testing) changes in circulating levels of CRP, IL-6, TNF-alpha, sICAM-1, sE-selectin, expression of the ¿?2-integrin subunits CD11a and CD11b on leukocytes, leukocyte activation (pseudopod formation), and peripheral blood mononuclear cell (PBMC) chemotaxis.
