VEGFC and brain neoplasm: Developing a nano‐plumber that coencapsulates the microenvironment regulator pro‐DHA and the lymphatic‐specific growth factor VEGF‐C, Chen et al significantly improves the neurological function of rodents with traumatic brain injury through enhanced glymphatic‐lymphatic drainage, suppressed microglia and astrocytes activation.[31] Overexpression of VEGF‐C improves clearance of senescent astrocytes and mitigates neuroinflammation.[32] Notably, VEGF‐C also shines a light on brain tumors.
