Description:
|
Lymphatic vessels periodically contract and relax to actively pump lymph, transport immune cells, and are critical for organ health. Lymphatic endothelial cells (LECs) regulate pump function by releasing vasoactive factors, nitric oxide (NO) and prostaglandins, in response to altered lymph flow and composition. It is understood that enhanced LEC NO production induces lymphatic pump failure and leads to organ dysfunction. Although recent radiation studies have reported loss of lymphatic function regarding high-dose radiation, effects of low-dose ionizing radiation on LECs have yet to be investigated thoroughly. Therefore, the goal of these studies to investigate the mechanisms by which low-dose ionizing radiation induces LEC dysfunction. Findings from these studies are expected to form the basis for the development of novel therapeutic strategies to treat organ dysfunction in radiotherapy patients. |
