L’ictus rappresenta la seconda causa di morte e la principale causa di disabilità in tutto il mondo, solitamente è responsabile di disabilità prolungata o permanente, a causa del danneggiamento del tessuto neurale. Data la scarsa capacità di autoriparazione del sistema nervoso, ci sono tecniche, in via di sperimentazione, per rendere possibile tale rigenerazione. In questi ultimi anni, la ricerca si è concentrata sull’utilizzo di organoidi, ossia masse di cellule e/o tessuti cresciuti artificialmente che assomigliano a un organo, al fine di trovare delle tecniche efficaci per la cura di malattie legate al deterioramento del tessuto nervoso. Questa tesi intende fornire una panoramica sull’utilizzo di organoidi con relative applicazioni al sistema nervoso centrale (SNC). Nella prima sezione viene presentata una descrizione del tessuto nervoso, illustrandone le componenti principali, le possibili lesioni e le cause dell’incapacità di autoriparazione. Viene poi fornita una spiegazione di cosa siano gli organoidi, le varie applicazioni e i limiti riscontrati nella loro realizzazione. Infine, viene spiegato più in dettaglio il loro utilizzo nella riparazione del SNC. In sintesi, le ricerche condotte negli ultimi anni hanno dimostrato che il trapianto di organoidi cerebrali è una potenziale terapia per la riparazione di circuiti neurali danneggiati, in maniera tale da cercare di ridurre o annullare la perdita di neuroni lesionati.

Abstract
Stroke is the second leading cause of death and the leading cause of disability worldwide, usually responsible for prolonged or permanent disability, due to damage to neural tissue. Given the nervous system's poor ability to repair itself, there are techniques being tested to make such regeneration possible. In recent years, research has focused on the use of organoids, i.e. artificially grown masses of cells and/or tissues that resemble an organ, in order to find effective techniques for the treatment of diseases related to the deterioration of nervous tissue. This thesis aims to provide an overview of the use of organoids with their applications to the central nervous system (CNS). In the first section, a description of nerve tissue is presented, illustrating its main components, possible injuries, and causes of the inability to self-repair. An explanation of what organoids are, the various applications and the limitations found in their production is then provided. Finally, their use in CNS repair is explained in more detail. In summary, research conducted in recent years has shown that brain organoid transplantation is a potential therapy for the repair of damaged neural circuits, in such a way as to try to reduce or cancel the loss of injured neurons.File | Dimensione | Formato | |
