Differential effects of Tau on the integrity and function of neurons essential for learning in Drosophila

…, S Grammenoudi, K Papanikolopoulou… - Journal of …, 2010 - Soc Neuroscience
Tauopathies are a heterogeneous group of neurodegenerative dementias involving
perturbations in the levels, phosphorylation, or mutations of the microtubule-binding protein Tau. …

[HTML][HTML] Formation of amyloid fibrils in vitro by human γD-crystallin and its isolated domains

K Papanikolopoulou, I Mills-Henry, SL Thol… - Molecular …, 2008 - ncbi.nlm.nih.gov
Purpose Amyloid fibrils are associated with a variety of human protein misfolding and protein
deposition diseases. Previous studies have shown that bovine crystallins form amyloid …

[HTML][HTML] Amyloid fibril formation from sequences of a natural β-structured fibrous protein, the adenovirus fiber

K Papanikolopoulou, G Schoehn, V Forge… - Journal of Biological …, 2005 - ASBMB
Amyloid fibrils are fibrous β-structures that derive from abnormal folding and assembly of
peptides and proteins. Despite a wealth of structural studies on amyloids, the nature of the …

[HTML][HTML] Formation of highly stable chimeric trimers by fusion of an adenovirus fiber shaft fragment with the foldon domain of bacteriophage t4 fibritin

K Papanikolopoulou, V Forge, P Goeltz… - Journal of Biological …, 2004 - ASBMB
The folding of β-structured, fibrous proteins is a largely unexplored area. A class of such
proteins is used by viruses as adhesins, and recent studies revealed novel β-structured motifs …

Drosophila tau negatively regulates translation and olfactory long-term memory, but facilitates footshock habituation and cytoskeletal homeostasis

K Papanikolopoulou, IG Roussou, JY Gouzi… - Journal of …, 2019 - Soc Neuroscience
Although the involvement of pathological tau in neurodegenerative dementias is indisputable,
its physiological roles have remained elusive in part because its abrogation has been …

[HTML][HTML] Mical modulates Tau toxicity via cysteine oxidation in vivo

…, EMC Skoulakis, K Papanikolopoulou - Acta neuropathologica …, 2022 - Springer
Tau accumulation is clearly linked to pathogenesis in Alzheimer’s disease and other
Tauopathies. However, processes leading to Tau fibrillization and reasons for its pathogenicity …

The two cysteines of tau protein are functionally distinct and contribute differentially to its pathogenicity in vivo

…, M Samiotaki, K Papanikolopoulou - Journal of …, 2021 - Soc Neuroscience
Although Tau accumulation is clearly linked to pathogenesis in Alzheimer's disease and other
Tauopathies, the mechanism that initiates the aggregation of this highly soluble protein in …

Temporally distinct phosphorylations differentiate Tau-dependent learning deficits and premature mortality in Drosophila

K Papanikolopoulou… - Human Molecular …, 2015 - academic.oup.com
Abnormally phosphorylated Tau protein, the major component of neurofibrillary tangles, is
critical in the pathogenesis of Alzheimer's disease and related Tauopathies. We used …

Adenovirus fibre shaft sequences fold into the native triple beta-spiral fold when N-terminally fused to the bacteriophage T4 fibritin foldon trimerisation motif

K Papanikolopoulou, S Teixeira, H Belrhali… - Journal of molecular …, 2004 - Elsevier
Adenovirus fibres are trimeric proteins that consist of a globular C-terminal domain, a central
fibrous shaft and an N-terminal part that attaches to the viral capsid. In the presence of the …

An assessment of the translational relevance of Drosophila in drug discovery

K Papanikolopoulou, A Mudher… - Expert opinion on drug …, 2019 - Taylor & Francis
Introduction: Drosophila melanogaster offers a powerful expedient and economical system
with facile genetics. Because of the high sequence and functional conservation with human …
