Lymphatic drainage pathway

The lymphatic drainage pathway is not a molecular target but refers to the network of lymphatic vessels and nodes responsible for collecting interstitial fluid, proteins, immune cells, and waste from tissues and transporting them back to the bloodstream[2][4][8]. These routes are essential for maintaining tissue fluid balance, supporting immune surveillance, and facilitating the absorption of dietary fats. Lymphatic drainage pathways are also important in pathophysiological contexts, such as tumor metastasis (via lymphatic dissemination of cancer cells), lymphedema (when drainage is impaired), and infection spread[2][4][7]. The development and function of these pathways depend on specialized lymphatic endothelial cells with molecular markers including LYVE-1, PROX1, PDPN, VEGFR3, and CCL21[1][5][6]. Despite their critical biological roles, "lymphatic drainage pathways" is a structural/anatomical descriptor and not a conventional therapeutic molecular target such as a receptor, enzyme, or transporter.
