La diversità microbica dell'Antartide è in gran parte inesplorata, ma i suoi microrganismi, adattati a condizioni estreme, possiedono un grande potenziale per applicazioni biotecnologiche. Questi estremofili hanno sviluppato strategie uniche, che includono modifiche nella regolazione genica e nelle vie metaboliche, rendendoli una preziosa fonte di molecole bioattive. Questo progetto di tesi tratta di ceppi fungini isolati da matrici antartiche, i quali hanno dimostrato un potenziale per le applicazioni terapeutiche. In particolare, alcuni funghi hanno mostrato la capacità di inibire la formazione di fibrille amiloidi di α-sinucleina, una proteina coinvolta nello sviluppo del morbo di Parkinson. Utilizzando saggi colorimetrici e tecniche cromatografiche accoppiate alla spettrometria di massa, alcuni prodotti sono stati estratti e testati in vitro al fine di caratterizzarne le proprietà biologiche. Data la necessità di trattamenti alternativi per le malattie neurodegenerative, i prodotti naturali potrebbero offrire punti di partenza essenziali per lo sviluppo di nuovi farmaci. Infatti, queste molecole per la loro intrinseca bioattività e diversità strutturale, potrebbero essere utilizzate come scaffold naturali e rappresentare candidati promettenti per lo sviluppo di terapie innovative per il morbo di Parkinson.

Abstract
Antarctica's microbial diversity is largely unexplored, but its microorganisms, adapted to extreme conditions, hold great potential for biotechnological applications. These extremophiles have evolved unique strategies, including changes in gene regulation and metabolic pathways, making them a valuable source of bioactive molecules. This thesis project deals with fungal strains isolated from Antarctic sources, which have demonstrated potential for therapeutic applications. In particular, some fungi have exhibited the ability to inhibit the formation of amyloid fibrils of α-synuclein a protein involved in the development of Parkinson’s disease. By using colorimetric assays and chromatography techniques coupled with mass spectrometry, some products were extracted and tested in vitro to characterize their biological properties. Due to the demand for alternative treatments of neurodegenerative disease, natural products could offer essential starting points for the generation of novel pharmaceuticals. In fact, these molecules, for their inherent bioactivity and structural diversity, could be used as natural scaffolds as promising candidates for the development of innovative treatments for Parkinson's disease| File | Dimensione | Formato | |
