Intraventricular hemorrhage (IVH) is the most fatal form of brain injury, yet a therapy directed at ameliorating intraventricular clot is very limited. There is accumulating evidence that an augmentation of the meningeal lymphatic (MLVs) functions might be a promising therapeutic target for IVH. In particular, the photostimulation (PS) of MLVs could be promising for non-invasive therapy of IVH via PS of clearance of red blood cells (RBCs) from the brain via MLVs. Indeed, we uncover that PS has therapeutic effects on IVH in mice reducing the mortality, improving the emotional status, accelerating the RBCs evacuation from the ventricles and increasing the ICP recovery. Our findings strongly suggest that the PS-mediated stimulation of drainage and clearing functions of MLVs can be a novel bedside, readily applicable and commercially viable technologies for treatment of IVH. These pilot results open new horizons in a non-invasive therapy of IVH via PS stimulation of regenerative lymphatic mechanisms.
