    Stabilization and structural analysis of a membrane-associated hIAPP aggregation intermediate

    Diana C Rodriguez Camargo, Kyle J Korshavn ... Ayyalusamy Ramamoorthy
    The ability of lipid nanodiscs to trap different types of amyloid intermediates, as successfully demonstrated in this study for human-IAPP, could become one of the most powerful approaches to dissect the complicated misfolding pathways of protein aggregation.

    Impaired retrograde transport of axonal autophagosomes contributes to autophagic stress in Alzheimer’s disease neurons

    Prasad Tammineni, Xuan Ye ... Qian Cai
    Amyloid-β oligomers associated with Alzheimer’s disease interact with dynein motors to impair retrograde transport of autophagic vesicles in neurons.

    LTP and memory impairment caused by extracellular Aβ and Tau oligomers is APP-dependent

    Daniela Puzzo, Roberto Piacentini ... Ottavio Arancio
    Oligomeric Amyloid-β and Tau, two proteins involved in Alzheimer's disease pathogenesis, require Amyloid Precursor Protein to enter neurons and exert their detrimental effect on synaptic plasticity and memory.

    Endoplasmic reticulum stress-independent activation of unfolded protein response kinases by a small molecule ATP-mimic

    Aaron S Mendez, Jennifer Alfaro ... Peter Walter
    A rationally designed small molecule ATP-mimetic activates IRE1 and PERK signaling in cells by inducing conformational changes that template the assembly of higher-order enzymatically active structures.

    Somatostatin binds to the human amyloid β peptide and favors the formation of distinct oligomers

    Hansen Wang, Lisa D Muiznieks ... Gerold Schmitt-Ulms
    The cyclic neuropeptide somatostatin binds to human Aβ1-42 through an interface that critically relies on a specific tryptophan, thereby blocking the propensity of Aβ to aggregate, a critical step in the pathobiology of Alzheimer's disease.

    Structural mapping of oligomeric intermediates in an amyloid assembly pathway

    Theodoros K Karamanos, Matthew P Jackson ... Sheena E Radford
    Solution NMR provides structural and kinetic information about oligomers on pathway to amyloid fibrils that are precisely structured but not cytotoxic.

    Structure-based inhibitors of amyloid beta core suggest a common interface with tau

    Sarah L Griner, Paul Seidler ... David S Eisenberg
    Aβ inhibitors effectively block its aggregation, while also reducing seeding of tau aggregation from Aβ, tau, and AD derived fibrils, suggesting the two share a structurally related disease relevant interface.

    An engineered monomer binding-protein for α-synuclein efficiently inhibits the proliferation of amyloid fibrils

    Emil Dandanell Agerschou, Patrick Flagmeier ... Alexander K Buell
    The high affinity α-synuclein-monomer binder AS69 converts into a strong sub-stoichiometric inhibitor of nucleation processes upon formation of the AS69-α-synuclein complex, achieving reduced aggregation in vitro and in vivo.

    McsB forms a gated kinase chamber to mark aberrant bacterial proteins for degradation

    Bence Hajdusits, Marcin J Suskiewicz ... Tim Clausen
    The McsB kinase is critical for protein quality control in Gram-positive bacteria, assembling a gated phosphorylation chamber during heat-shock conditions to selectively mark misfolded proteins for degradation.

    A Drosophila model of neuronal ceroid lipofuscinosis CLN4 reveals a hypermorphic gain of function mechanism

    Elliot Imler, Jin Sang Pyon ... Konrad E Zinsmaier
    Genetic analysis of a CLN4 Drosophila model suggests that the disease-causing alleles act as dominant gain of function mutations that cause CSPα oligomerization and impair secretory and prelysosomal trafficking.
