abstract = {Advances in neonatology have significantly reduced mortality rates due to prematurity. However, complications of prema-
turity have barely changed in recent decades. Germinal matrix-intraventricular hemorrhage (GM-IVH) is one of the most
severe complications of prematurity, and these children are prone to suffer short- and long-term sequelae, including cerebral
palsy, 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 7
and 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 mouse
model 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 myelin
basic 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 support
the 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},
