Glycation potentiates α-synuclein-associated neurodegeneration in synucleinopat...
Miranda, Hugo Vicente; Szegő, Éva M.; Oliveira, Luís M. A.; Breda, Carlo; Darendelioglu, Ekrem; Oliveira, Rita M. de; Ferreira, Diana G.α-Synuclein misfolding and aggregation is a hallmark in Parkinson’s disease and in several other neurodegenerative diseases known as synucleinopathies. The toxic properties of α-synuclein are conserved from yeast to man, but the precise underpinnings of the cellular pathologies associated are still elusive, complicating the development of effective therapeutic strategies. Combining molecular genetics with targe...

shRNA-Based Screen Identifies Endocytic Recycling Pathway Components That Act a...
Gonçalves, Susana A; Macedo, Diana; Raquel, Helena; Simões, Pedro D; Giorgini, Flaviano; Ramalho, José S; Barral, Duarte C; Ferreira Moita, LuísAlpha-Synuclein (aSyn) misfolding and aggregation is common in several neurodegenerative diseases, including Parkinson's disease and dementia with Lewy bodies, which are known as synucleinopathies. Accumulating evidence suggests that secretion and cell-to-cell trafficking of pathological forms of aSyn may explain the typical patterns of disease progression. However, the molecular mechanisms controlling aSyn agg...
Copy-number variation of the neuronal glucose transporter gene SLC2A3 and age o...
Vittori, Angelica; Breda, Carlo; Repici, Mariaelena; Orth, Michael; Roos, Raymund A. C.; Outeiro, Tiago; Giorgini, Flaviano; Hollox, Edward J.Huntington's disease (HD) is a devastating neurodegenerative disorder which is inherited in an autosomal dominant manner. HD is caused by a trinucleotide CAG repeat expansion that encodes a polyglutamine stretch in the huntingtin (HTT) protein. Mutant HTT expression leads to a myriad of cellular dysfunctions culminating in neuronal loss and consequent motor, cognitive and psychiatric disturbances in HD patients...
The small GTPase Rab11 co-localizes with α-synuclein in intracellular inclusion...
Chutna, Oldriska; Goncalves, Susana; Villar-Pique, Anna; Guerreiro, Patrícia; Marijanovic, Zrinka; Mendes, Tiago; Ramalho, JoséAlpha-synuclein (aSyn) misfolding and aggregation are pathological features common to several neurodegenerative diseases, including Parkinson's disease (PD). Mounting evidence suggests that aSyn can be secreted and transferred from cell to cell, participating in the propagation and spreading of pathological events. Rab11, a small GTPase, is an important regulator in both endocytic and secretory pathways. Here, ...
Yeast as a model for studying human neurodegenerative disorders
Miller-Fleming, Leonor; Giorgini, Flaviano; Outeiro, TiagoProtein misfolding and aggregation are central events in many disorders including several neurodegenerative diseases. This suggests that alterations in normal protein homeostasis may contribute to pathogenesis, but the exact molecular mechanisms involved are still poorly understood. The budding yeast Saccharomyces cerevisiae is one of the model systems of choice for studies in molecular medicine. Modeling human...
