We observed a conserved three-dimensional anatomy of MLVs in mice and humans that aligned with dural venous sinuses but not with nasal CSF outflow, and we discovered an extended anterior MLV network around the cavernous sinus, with exit routes through the foramina of emissary veins. Here, we used light-sheet fluorescence microscopy (LSFM) imaging of mouse whole-head preparations after OVA-A555 tracer injection into the cerebrospinal fluid (CSF) and performed real-time vessel-wall (VW) magnetic resonance imaging (VW-MRI) after systemic injection of gadobutrol in patients with neurological pathologies. Whether MLVs exist in the anterior part of the murine and human skull and how they connect with the glymphatic system and extracranial lymphatics remained unclear. more Meningeal lymphatic vessels (MLVs) were identified in the dorsal and caudobasal regions of the dura mater, where they ensure waste product elimination and immune surveillance of brain tissues.

We observed a conserved 3D-anatomy of MLVs in mice and humans, and we discovered an extended anterior network around the dural cavernous sinus including multiple capillary beds and exit routes through the foramina of emissa. In humans, we performed real-time magnetic resonance vessel wall imaging (MR-VWI) after systemic gadobutrol injections. Here, we generated three-dimensional (3D) maps of MLV drainage by light-sheet fluorescence microscopy (LSFM) imaging of mouse whole-head preparations following fluorescent OVA-A555 tracer injections into the CSF. ![]() Whether MLVs exist in the complex anterior part of the murine and human skull, and how they connect with the glymphatic system and extracranial lymphatic vasculature remained unclear.

Using mouse knockout models, we show that Sema3A is selectively required for lymphatic valve formation, via interaction with Nrp1 and PlexinA1. Methods and Results: We show that Sema3A mRNA is expressed in lymphatic vessels and that Sema3A protein binds to lymphatic valves expressing the Neuropilin-1 (Nrp1) and PlexinA1 receptors. Objective: We investigated if the repulsive axon guidance molecule Semaphorin3A (Sema3A) plays a role in lymphatic valve formation. How lymphatic valve formation is regulated remains largely unknown. Defective formation of lymphatic valves leads to lymphedema, a progressive and debilitating condition for which curative treatments are currently unavailable. Fluid transport depends on the presence of intraluminal valves within lymphatic collectors. more Rationale: The lymphatic vasculature plays a major role in fluid homeostasis, absorption of dietary lipids, and immune surveillance. Produced by Bob Thiele.Rationale: The lymphatic vasculature plays a major role in fluid homeostasis, absorption of dieta. Recording as a Leader Leon Thomas: SPIRITS KNOWN AND UNKNOWN-NEW VOCAL FRONTIERSįlying Dutchman 1969. In the liner notes for one early Leon Thomas album it is reported, "Of Leon Thomas' singing on Pharoah Sanders' KARMA, Will Smith in Jazz & Pop Magazine observed: 'The voice projection of the lyrics is good and full, and leads to a wordless yodel sounding not unlike an American Indian call-the moaning of spirits known and unknown.'" While Thomas had a lyrical side, his voice became an instrument unto itself. Of "The Creator Has A Master Plan", Thomas married his understandings of jazz and blues with an exploration of different African vocal traditions. The vocalist and co-author with Pharoah Sanders But none exemplified the creativity of the music like singer/percussionist Leon Thomas. Many vocalists of the early 1970s found themselves in the world of spiritual, roots-oriented, consciousness jazz: DeeDee Bridgewater, Jean Carn, Jeanne Lee, Sherry Scott, Andy Bey, and others. ![]()
