Azobenzénové deriváty ako potenciálne terapeutiká pre Alzheimerovu chorobu
Azobenzenes as potential Alzheimer\’s theranostic agents
Program: Mobility
Project leader: RNDr. Bednáriková Zuzana, PhD.
Annotation: Amyloid fibrils of amyloid β (Aβ) peptides are a neuropathological feature of Alzheimer\’s disease (AD). AD is one of the world\’s fastest-growing neurological diseases with substantial economic and societal impact, but no cure is currently available. Therefore, the exploration of novel treatment approaches is in high demand. The project\’s main objective is to study the ability of azobenzene molecules to affect targets associated with the amyloid cascade of AD pathogenesis. The project will employ the lever-like potential of azobenzene molecules to dissociate fibrillar aggregates of Aβ peptides and inhibit the proteolytic activity of β-secretase. We will integrate in vitro, in silico, and cells workflow to find a possible alternative therapy against this devastating disease. Moreover, this collaborative research partnership will present an excellent opportunity for both teams\’ young members to learn new techniques in the well-equipped laboratories at the Polish and Slovak Academies of Sciences and gain new experience by working in an international scientific environment.

ANOMATY – Interakcie amyloidných fibríl a nanočastíc pre biomedicínske, biochemické a inžinierske aplikácie
Interactions of nanoparticles with amyloid fibrils: from therapy to nanomaterials
Program: Bilateral – other
Project leader: doc. RNDr. Gažová Zuzana, DrSc.
Annotation: Nanoparticles represent a powerful platform with a large potential for biomedicine and engineering applications.The formation of amyloid aggregates is unfavorable in vivo as they are associated with the pathogenesis of many human diseases, yet, amyloid fibrils have the potential to be engineered into novel materials. However, there is still little known about the interactions between amyloid fibrils and nanoparticles that can provide new enhanced NPs functions. The project aims to investigate the interaction of amyloid fibrils formed from native globular proteins and nanoparticles to utilize or enhance the NPs applications as catalysts in engineering applications or possible disaggregation agents to treat amyloid-related diseases (Alzheimer´s disease, diabetes mellitus). We will determine the relationship between amyloid fibrils (formed from lysozyme, insulin, and α -lactalbumin) and Au-, Ag- and Pd –nanoparticles with different surface chemistry (size, charge, functionalization). Moreover, we will perform a systematic study of globular proteins\’ propensity to form amyloid fibrils with controlled properties. The proposed objectives will be achieved by combining experimental techniques with computational methods routinely used in respective scientific teams. Moreover, the data about fibrils\’ structural and physico-chemical properties might fill the empty spaces in a big biology puzzle – pathophysiology of amyloid-related diseases.

NGP-NET – Neglobulárne proteíny – od sekvencie ku štruktúre, funkcii a aplikácii v molekulárnej fyziopatológii
Non-globular proteins – from sequence to structure, function and application in molecular physiopathology
Program: COST
Project leader: doc. RNDr. Gažová Zuzana, DrSc.
Annotation: Non-globular proteins (NGPs) encompass different molecular phenomena that defy the traditional sequence-structure-function paradigm. NGPs include intrinsically disordered regions, tandem repeats, aggregating domains, low-complexity sequences and transmembrane domains. Although growing evidence suggests that NGPs are central to many human diseases, functional annotation is very limited. It was recently estimated that close to 40 of all residues in the human proteome lack functional annotation and many of these are NGPs. While a better understanding of NGPs is crucial to fully comprehend human molecular physiopathology, progress has been hampered so far by the lack of a systematic approach to their study.This Action Proposal aims to create a pan-European scientific network of groups that work on NGPs to strengthen, focus and coordinate research in this field. It proposes to develop a novel classification of NGPs by consensus among interested experts that will be showcased on a newly developed web site, along with meetings, training schools and scientific missions on NGP-related topics.

Objasnenie počiatočných štádií amyloidnej agregácie proteínov – od mechanizmu k terapii
Unraveling the early events of protein amyloid aggregation – from mechanism to therapy
Program: VEGA
Project leader: doc. RNDr. Gažová Zuzana, DrSc.
Annotation: Structural changes of poly/peptides leading to the formation of amyloid aggregates are associated with incurablediseases, like Alzheimer\’s disease or diabetes. While the general mechanisms of fibril formation and theircharacterization are well reported, the early events during poly/peptide fibrillation are still unclear. The project isfocused on understanding the early events mechanisms leading to the formation of pre-fibrillar (partially un/foldedintermediates, nuclei, oligomers) and fibrillar amyloid aggregates of selected globular and intrinsically disorderedproteins. Our focus will be the study of the kinetics of pre-fibrillar structures formation, their morphology, andcytotoxicity, under various experimental conditions, and in the presence of selected interacting partners (smallmolecules, nanoparticles). The obtained results will contribute to understanding the early events of amyloidaggregation and identifying the inhibitors with therapeutic potential for amyloid diseases.

Samousporiadanie poly/peptidov do amyloidných agregátov – mechanizmus, inhibícia a cytotoxicita
Self-assembly of poly/peptides into amyloid aggregates – mechanism, inhibition and cytotoxicity
Program: VEGA
Project leader: doc. RNDr. Gažová Zuzana, DrSc.
Annotation: Amyloid supramolecular complexes formed by poly/peptides are the most prevalent naturally occurring self-assembling systems. Formation of such complexes affects function of poly/peptides and is associated with more than 30 serious amyloid-related diseases such as Alzhemer’s disease or diabetes mellitus. The exactmechanism of amyloid self-assembly of poly/peptides is not known yet and no effective treatment of amyloidosis is established. The goal of the project is to study the mechanism of the amyloid aggregation of poly/petides with different native structures and identification of inhibitors of poly/peptide self-assembly since the inhibition of amyloid formation is one of the possible therapeutic approaches against amyloid-related diseases. We will focus on the determination of the correlation between the morphology of amyloid aggregates and their cytotoxicity as well as on the relationship between structure of the effective inhibitors and their anti-amyloid activity.
