We therefore hypothesized that encapsulating mNGF in nanoparticles would facilitate BBB transit, increase delivery to the brain parenchyma, and consequently improve the treatment of traumatic brain injury (TBI).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Nanoparticles were used to encapsulate the high\u2010molecular\u2010weight protein mNGF to improve its delivery. Traumatic brain injury (TBI) was induced in mice, which were then allocated to four groups, including a sham group. Intramuscular injections of mNGF\u2014either free or nanoparticle\u2010encapsulated\u2014were administered. To elucidate the mechanism of action, the aquaporin\u20104 inhibitor 2\u2010nicotinamide\u20101,3,4\u2010thiadiazole (TGN\u2010020) was additionally given to the nanoparticle group. Glymphatic function (cerebrospinal fluid influx and efflux) was quantified by immunofluorescence. Blood\u2013brain barrier integrity, peri\u2010lesional parenchymal structure, and axonal repair were examined using Evans blue extravasation, immunofluorescence, and Western blotting. Neuronal apoptosis and focal neurological damage were measured with TUNEL staining and Western blot analysis. Functional outcomes were assessed with the modified Neurological Severity Score, rotarod performance, and the Morris water maze.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Nanoparticle encapsulation markedly increased the amount of mNGF that reached the brain parenchyma relative to conventional administration. Enhanced delivery enabled substantially more exogenous mNGF to traverse the BBB in TBI mice than did uncoated mNGF. The treatment attenuated TBI\u2010induced neuronal apoptosis, up\u2010regulated genes involved in neurogenesis and myelinogenesis, restored glymphatic inflow and outflow, repaired BBB structure and function, and mitigated cognitive deficits. These benefits were abolished by the aquaporin\u20104 inhibitor TGN\u2010020, indicating that mNGF improves TBI outcome by correcting AQP4 dysfunction. To our knowledge, this is the first demonstration that nanocrystallized mNGF can cross the BBB efficiently after TBI and thereby foster neural repair and functional recovery.<\/jats:p>\n
