Abstract
Formation of amyloid-beta (Aβ) oligomer pores in the membrane of neurons has been proposed to explain neurotoxicity in Alzheimer's disease (AD). Here, we present the three-dimensional structure of an Aβ oligomer formed in a membrane mimicking environment, namely an Aβ(1-42) tetramer, which comprises a six stranded β-sheet core. The two faces of the β-sheet core are hydrophobic and surrounded by the membrane-mimicking environment while the edges are hydrophilic and solvent-exposed. By increasing the concentration of Aβ(1-42) in the sample, Aβ(1-42) octamers are also formed, made by two Aβ(1-42) tetramers facing each other forming a β-sandwich structure. Notably, Aβ(1-42) tetramers and octamers inserted into lipid bilayers as well-defined pores. To establish oligomer structure-membrane activity relationships, molecular dynamics simulations were carried out. These studies revealed a mechanism of membrane disruption in which water permeation occurred through lipid-stabilized pores mediated by the hydrophilic residues located on the core β-sheets edges of the oligomers.

Abstract
The formation of amyloid-β peptide (Aβ) oligomers at the cellular membrane is considered a crucial process that underlies neurotoxicity in Alzheimer's disease (AD). To obtain structural information on this type of oligomers, we were inspired by membrane protein approaches used to stabilize, characterize, and analyze the function of such proteins. Using these approaches, we developed conditions under which Aβ42, the Aβ variant most strongly linked to the aetiology of AD, assembles into an oligomer that inserts into lipid bilayers as a well-defined pore and adopts a specific structure with characteristics of a β-barrel arrangement. We named this oligomer β-barrel Pore-Forming Aβ42 Oligomer (βPFOAβ42). Here, we describe detailed protocols for its preparation and characterization. We expect βPFOAβ42 to be useful in establishing the involvement of membrane-associated Aβ oligomers in AD.

Abstract
In recent decades, peptide blood-brain barrier shuttles have emerged as a promising solution for brain drugs that are not able to enter this organ. The research and development of these compounds involve the use of in vitro cell-based models of the BBB. Nevertheless, peptide transport quantification implies the use of large amounts of peptide (upper micromolar range for RP-HPLC-PDA) or of derivatives (e.g. fluorophore or quantum-dot attachment, radiolabeling) in the donor compartment in order to enhance the detection of these molecules in the acceptor well, although their structure is highly modified. Therefore, these methodologies either hamper the use of low peptide concentrations, thus hindering mechanistic studies, or do not allow the use of the unmodified peptide. Here we successfully applied a MALDI-TOF MS methodology for transport quantification in an in vitro BBB cell-based model. A light version of the acetylated peptide was evaluated, and the transport was subsequently quantified using a heavy internal standard (isotopically acetylated). We propose that this MALDI-TOF MS approach could also be applied to study the transport across other biological barriers using the appropriate in vitro transport models (e.g. Caco-2, PAMPA).

Abstract
Low effectiveness and resistance to treatments are commonplace in disorders of the central nervous system (CNS). These issues concern mainly the blood-brain barrier (BBB), which preserves homeostasis in the brain and protects this organ from toxic molecules and biohazards by regulating transport through it. BBB shuttles—short peptides able to cross the BBB—are being developed to help therapeutics to cross this barrier. BBB shuttles can be discovered by massive exploration of chemical diversity (e.g. computational means, phage display) or rational design (e.g. derivatives from a known peptide/protein able to cross). Here we present the selection of a peptide shuttle (HAI) from several candidates and the subsequent in-depth in vitro and in vivo study of this molecule. In order to explore the chemical diversity of HAI and enhance its biostability, and thereby its bioactivity, we explored two new protease-resistant versions of HAI (i.e. the retro-D-version, and a version that was N-methylated at the most sensitive sites to enzymatic cleavage). Our results show that, while both versions of HAI are resistant to proteases, the retro-D-approach preserved better transport properties.

Abstract
Peptides are experiencing a new era in medical research, finding applications ranging from therapeutics to vaccines. In spite of the promising properties of peptide pharmaceuticals, their development continues to be hindered by three weaknesses intrinsic to their structure, namely protease sensitivity, clearance through the kidneys, and immune system activation. Here we report on two retro-D-peptides (H2N-hrpyiah-CONH2 and H2N-pwvpswmpprht-CONH2), which are protease-resistant and retain the original BBB shuttle activity of the parent peptide but are much less immunogenic than the parent peptide. Hence, we envisage that retro-D-peptides, which display a similar topological arrangement as their parent peptides, will expand drug design and help to overcome factors that lead to the failure of peptide pharmaceuticals in pre- and clinical trials. Furthermore, we reveal requirements to avoid or elicit specific humoral responses to therapeutic peptides, which might have a strong impact in both vaccine design and peptide therapeutic agents.

Abstract
The modulation of protein–protein interactions (PPIs) is emerging as a highly promising tool to fight diseases. However, whereas an increasing number of compounds are able to disrupt peptide‐mediated PPIs efficiently, the inhibition of domain–domain PPIs appears to be much more challenging. Herein, we report our results related to the interaction between vascular endothelial growth factor (VEGF) and its receptor (VEGFR). The VEGF–VEGFR interaction is a typical domain–domain PPI that is highly relevant for the treatment of cancer and some retinopathies. Our final goal was to identify ligands able to bind VEGF at the region used by the growth factor to interact with its receptor. We undertook an extensive study, combining a variety of experimental approaches, including NMR‐spectroscopy‐based screening of small organic fragments, peptide libraries, and medicinal plant extracts. The key feature of the successful ligands that emerged from this study was their capacity to expose hydrophobic functional groups able to interact with the hydrophobic hot spots at the interacting VEGF surface patch.

Abstract
Drug delivery across the blood–brain barrier (BBB) is a formidable challenge for therapies targeting the central nervous system. Although BBB shuttle peptides enhance transport into the brain non‐invasively, their application is partly limited by lability to proteases. The present study proposes the use of cyclic peptides derived from venoms as an affordable way to circumvent this drawback. Apamin, a neurotoxin from bee venom, was minimized by reducing its complexity, toxicity, and immunogenicity, while preserving brain targeting, active transport, and protease resistance. Among the analogues designed, the monocyclic lactam‐bridged peptidomimetic MiniAp‐4 was the most permeable. This molecule is capable of translocating proteins and nanoparticles in a human‐cell‐based BBB model. Furthermore, MiniAp‐4 can efficiently deliver a cargo across the BBB into the brain parenchyma of mice.
