Meningeal lymphatics are reported to play a role in draining viruses from the central nervous system. The function of these lymphatics is being studied in relation to various conditions, including brain metastases, inflammatory diseases, and glioma management. Research suggests that the meningeal lymphatic system may be involved in both protective and detrimental processes, and its function may be affected by factors such as age and imbalance in the glymphatic-meningeal lymphatic system.
