Research on the Human Lymphatic Mononuclear Cells is essential to the study of the innate and adaptive immune system, lymphedema, lymphoma, autoimmune diseases (e.g., rheumatoid arthritis), metastatic cancer spread via lymphatics, and chronic inflammatory conditions. Lymph nodes are bean-shaped organs of the lymphatic system, distributed throughout the body but clustered in the neck, armpits, and groin. They consist of a capsule, cortex, and medulla, and contain a large number of lymphocytes. Lymph nodes are important parts of the human immune system, with their primary functions being to filter lymphatic fluid, remove pathogens, and activate immune cells to fight infections.
