However, complications of prema-turity have barely changed in recent decades. Germinal matrix-intraventricular hemorrhage (GM-IVH) is one of the mostsevere complications of prematurity, and these children are prone to suffer short- and long-term sequelae, including cerebralpalsy, cognitive and motor impairments, or neuropsychiatric disorders. Nevertheless, GM-IVH has no successful treatment.VP3.15 is a small, heterocyclic molecule of the 5-imino-1,2,4-thiadiazole family with a dual action as a phosphodiesterase 7and glycogen synthase kinase-3β (GSK-3β) inhibitor. VP3.15 reduces neuroinflammation and neuronal loss in other neuro-degenerative disorders and might ameliorate complications associated with GM-IVH. We administered VP3.15 to a mousemodel of GM-IVH. VP3.15 reduces the presence of hemorrhages and microglia in the short (P14) and long (P110) term.It ameliorates brain atrophy and ventricle enlargement while limiting tau hyperphosphorylation and neuronal and myelinbasic protein loss. VP3.15 also improves proliferation and neurogenesis as well as cognition after the insult. Interestingly,plasma gelsolin levels, a feasible biomarker of brain damage, improved after VP3.15 treatment. Altogether, our data supportthe beneficial effects of VP3.15 in GM-IVH by ameliorating brain neuroinflammatory, vascular and white matter damage,ultimately improving cognitive impairment associated with GM-IVH PB Springer SN 1868-4483 YR 2024 FD 2024-01-17 LK http://hdl.handle.net/10498/31858 UL http://hdl.handle.net/10498/31858 LA eng DS Repositorio Institucional de la Universidad de Cádiz RD 10-nov-2026
