Advances in formal Slavic linguistics 2017
2020, zbornik recenziranih znanstvenih prispevkov na mednarodni ali tuji konferenci

Opis: Advances in Formal Slavic Linguistics 2017 is a collection of fifteen articles that were prepared on the basis of talks given at the conference Formal Description of Slavic Languages 12.5, which was held on December 7-9, 2017, at the University of Nova Gorica. The volume covers a wide array of topics, such as control verbs, instrumental arguments, and perduratives in Russian, comparatives, negation, n-words, negative polarity items, and complementizer ellipsis in Czech, impersonal se-constructions and complementizer doubling in Slovenian, prosody and the morphology of multi-purpose suffixes in Serbo-Croatian, and indefinite numerals and the binding properties of dative arguments in Polish. Importantly, by exploring these phenomena in individual Slavic languages, the collection of articles in this volume makes a significant contribution to both Slavic linguistics and to linguistics in general.

Dissecting the role of REEP1 in preventing Tau-mediated neurodegeneration in a D.melanogaster Alzheimer's disease model
Alessio Guglielmi, 2019, doktorska disertacija

Opis: Tau is natively an unfolded protein that promotes the assembly and the stability of the axonal microtubules in the central nervous system. Increased formation of Tau protein aggregates has been causatively implicated in several neurodegenerative diseases called tauopathies. In the present study, we used the Drosophila melanogaster system to express the longest isoform of human Tau (2N4R) in the nervous system of adult flies, recreating the main features of the human pathology. Herein, this Tau-mediated neurodegeneration model was used as a platform to perform genetic screenings to identify putative modifiers of Tau toxicity. Our strategy exploited the modulation of genes considered as risk factors of Alzheimer’s disease (AD), Frontotemporal Dementias and other neurodegenerative diseases by RNA interference in vivo. This approach allowed us to identify a new gene which participates in the neuronal response against Tau induced neurotoxicity in Drosophila: D-Reep1, homologue of human REEP1 gene (h-Reep1). D-Reep1 knockout flies showed no apparent phenotypes in physiological growing and developmental conditions, however, they showed peculiar sensitivity to stress conditions. In addition, D-Reep1 knockout enhanced the neurodegeneration mediated by Tau expression in Drosophila eyes. On the contrary, the overexpression of UAS-D-Reep1 and UAS-h-Reep1 abolished the typical rough eye phenotype induced by the presence of Tau. The Co-expression of D-Reep1 in Tau backgrounds did not alter the phosphorylation pattern of this protein while, the presence of D-Reep1 seemed to prevent the formation of Tau aggregates in vivo. Thus, the data support the idea that D-Reep1 exerts a protective role on Tau induced toxicity which is independent of its phosphorylation status. In this work, I analysed the mechanisms behind the neuroprotective role of D-Reep1 and, in particular, I found that REEP1 is involved in the regulation of the unfolded protein response (UPR) through the PERK-ATF4 cascade within the ER. By the activation of this pathway, the neurotoxic aggregates of Tau are removed from Drosophila neuronal tissues rescuing the normal characteristics of the affected tissues. Evidences also suggest that the activation of autophagy was behind the removal of Tau aggregates, providing new molecular information about the physiological role of D Reep1 in the nervous system.
