Atomic resolution map of the soluble amyloid beta assembly (Aβ<sub>n</sub>) “toxic surfaces” that facilitate early pathogenic events in Alzheimer's disease (AD).
Abstract With the advent of polymyxin B (PmB) resistance in bacteria, mechanisms for mcr -1 are crucial importance design novel therapeutics. The phenotype is known to decrease membrane charge and increase packing by modification bacterial outer membrane. We used X-ray diffraction, Molecular Dynamics simulations, electrochemistry, leakage assays determine location PmB different membranes assess damage. By varying lipid tail independently, we show that increasing surface promotes penetration...
Signaling events at membranes are often mediated by membrane lipid composition or physical properties. These properties could act either favoring the binding of downstream effectors modulating their activity. Several proteins can sense/generate curvature (i.e. shape). However, modulation activity enzymes a membrane's shape has not yet been reported. Here, using cell-free assay with purified diacylglycerol kinase ɛ (DGKɛ) and liposomes, we studied acyl-chain specificity an enzyme...
In the brain, α-synuclein (aSN) partitions between free unbound cytosolic and membrane bound forms modulating both its physiological pathological role complicating study due to structural heterogeneity. Here, we use an interdisciplinary, synergistic approach characterize properties of aSN:lipid mixtures, isolated co-structures, aSN in mammalian cells. Enabled by isolation membrane-bound state, show that within previously described N-terminal anchor, interaction relies on tail (NTT) head...
Amyloid- β aggregates play a causative role in Alzheimer's disease. These are product of the physical environment provided by basic neuronal membrane, composed lipid bilayer. The intrinsic properties bilayer allow amyloid- peptides to nucleate and form well-ordered cross- sheets within membrane. Here, we correlate aggregation hydrophobic fragment protein, A 25 - 35 , with hydrophobicity, fluidity, charge density We summarize recent biophysical studies model membranes relate these process...
Integrative structure of a complete cytokine receptor in nanodisc opens for mechanistic decoding disorder-based biology.
As more artificial intelligence (AI) applications are integrated into healthcare, there is an urgent need for standardization and quality-control measures to ensure a safe successful transition of these novel tools clinical practice. We describe the role silent trial, which evaluates AI model on prospective patients in real-time, while end-users (i.e., clinicians) blinded predictions such that they do not influence decision-making. present our experience evaluating previously developed...
Exposure to research data and artificial intelligence (AI) model predictions may lead many sources of bias in clinical decision-making evaluation. These include anchoring bias, automation leakage. In this case study, we introduce a new source termed "induced belief revision," which have discovered through our experience developing testing an AI predict obstructive hydronephrosis children based on their renal ultrasounds. After silent trial model, observed unintentional but clinically...
Objective To compare the outcomes of pre‐ vs postnatally diagnosed posterior urethral valves (PUV) at two large paediatric centres in North America to ascertain if prenatal diagnosis PUV is associated with better outcomes. Patients and Methods All boys were identified institutions between 2000 2020 (The Hospital for Sick Children [SickKids, SK] Children’s Philadelphia [CHOP]). Baseline characteristics outcome measures compared those postnatally. Main interest included progression chronic...
Caffeine partitions in lipid membranes the head to tail interface and leads a thickening defluidification.
Alpha synuclein (αS) oligomers are a key component of Lewy bodies implicated in Parkinson's disease (PD). Although primarily intracellular, extracellular αS exocytosed from neurons also contributes to PD pathogenesis through prion-like transmission mechanism. Here, we show at progressive degrees resolution that the most abundantly expressed protein, human serum albumin (HSA), inhibits oligomer (αSn) toxicity three-pronged First, endogenous HSA targets αSn with sub-μM affinity via...
