This study provides evidence of lymphatic vessels in the mouse brain, specifically in the cortex, thalamus, and hippocampus. Using confocal microscopy, Western blotting, and real-time PCR, lymphatic vessels were identified by the expression of Lyve1, Prox1, and VEGFC, alongside endothelial markers CD31 and CD34. Paraffin-embedded brain slices from wild-type Balb/C mice were stained with antibodies against Lyve1, CD31, and CD34, revealing lymphatic vessels through 2D and 3D imaging. A coiled 3D structure of lymphatic vessels was observed in the hippocampus, indicating a complex drainage network. Western blot and real-time PCR analyses confirmed the presence of lymphatic and endothelial markers at the protein and mRNA levels. These findings demonstrate a lymphatic system extending from the meninges into deeper brain regions, offering insights into immune and waste clearance pathways in the central nervous system and potential therapeutic targets for neurological disorders.

The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
