Unatoč dostignućima u razumijevanju važnosti moždanog izvanstaničnog matriksa (ECM, difuznog ili kondenziranog kao perineuronske mreže, PNN) za fiziološke i patološke procese u mozgu, on je još uvijek daleko manje prepoznat i istražen od staničnih elemenata. U cilju novih spoznaja o ključnim molekulama i razvojnim događajima u ECM-u, posebno onih koji su izraženi u ljudskom mozgu, istraživači sa HIIM-a u  Zagrebu i Tehničkog Sveučilišta u Dresdenu, s kliničarima-istraživačima s KBC Zagreb i AKH Sveučilišta u Beču će ujediniti znanstvene pristupe, modele (ljudski, štakorski i organoidi) i metodologije (histološke, molekularne, bihevioralne i magnetska rezonancija (MR) 3T i 7T) kako bi se odgovorilo na sljedeće znanstvene izazove: (1) otkriti značajne razlike u sastavnicama ECM-a između fetalnih zona, odjeljaka, aksonskih (strata) i kortikalnih (layers) slojeva; (2) otkriti vremensko-prostorne obrasce ekspresije molekula ECM-a telencefaličke stijenke i bazalnih ganglija u razvitku i definirati ključne vremenske točke ireverzibilnih promjena ekspresijskih obrasca prijelazom u zreli oblik ECM-a; (3) otkriti korelate fetalnih ECM obrazaca na slikovnim prikazima MR u zdravlju (čovjek i štakor) i nakon blage do umjerene perinatalne hipoksije (štakor); (4) otkriti molekularni fenotip, staničnu i prostorno-vremensku distribuciju PNN u razvitku (čovjek i štakor) i promjene istih nakon perinatalne hipoksije u štakora te (5) korelirati ove promjene s bihevioralnim posljedicama hipoksije. Očekujemo da će istraživanje omogućiti da procijenimo značaj i ulogu molekula, obrazaca i reorganizacijskih procesa moždanog ECM-a. Rezultati projekta bit će nove znanstvene spoznaje, publikacije, unapređenje edukacije i pozicioniranje za daljnje međunarodne projekte usmjerene na razvoj novih istraživačkih, dijagnostičkih i terapijskih strategija za neurorazvojne poremećaje kao što su kognitivni deficiti, epilepsija, autizam ili shizofrenija.

Despite recent advances in the understanding of the importance of the neural extracellular matrix (ECM,  diffused or condensed as perineuronal nets, PNN) for physiological and pathological processes in the brain, it is still widely less recognized and researched than different neural cellular elements. To combat the lack of knowledge on key ECM players relevant for human brain development, basic researchers (at CIBR, Zagreb, and TU, Dresden) and clinically oriented researchers (at CHC Zagreb, AKH Vienna) will unite scientific approaches, models (human, rat, and organoids) and methodologies (3T and 7T magnetic resonance imaging (MRI), histological, molecular and behavioral), to address the following scientific aims: (1) to detect major differences in ECM constituents among the fetal brain zones, compartments, axonal strata, and cortical layers; (2) to disclose the different ECM expression patterns in the developing brain and (3) define the crucial time points of ECM expression patterns irreversible up-turns in transition to mature ECM form; (4) to reveal the correlates of the fetal ECM patterns in high-resolution MRI in health (human, rat) and after mild to moderate perinatal hypoxia in rat; (5) to disclose molecular phenotype, neuronal and spatial-temporal distribution of the PNN in health (human and rat) and their charges after perinatal hypoxia in rat and (6) to correlate the changes with behavioral consequences of the hypoxic lesion. These will enable us to evaluate the significance and the role of ECM constituents, and ECM reorganization, for the developmental processes (proliferation, migration, axon growth, folding, and synaptogenesis) in the human brain, in health and disorders. The outcome of the project will be new knowledge, publications, advances in education, and positioning for joint international proposals towards ECM-based research, diagnostic and therapeutic strategies, for neurodevelopmental disorders as cognitive disabilities, epilepsy, autism or schizophrenia
