The Membrane Proximal External Region of the HIV-1 Envelope Glycoprotein gp41 Contributes to the Stabilization of the Six-Helix Bundle Formed with a Matching N′ Peptide [PDF]

open access: yesBiochemistry, 2008
The HIV-1 envelope glycoprotein gp41 undergoes a sequence of extensive conformational changes while participating in the fusion of the virus with the host cell. Since the discovery of its postfusion conformation, the structure and function of the protease-resistant six-helix bundle (6-HB) have been the subject of extensive investigation.

Thalamo‐Lesional Connectivity Signatures of Bilateral Tonic–Clonic Seizures in Focal Cortical Dysplasia‐Related Epilepsy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Focal cortical dysplasia (FCD) is the most common etiology of drug‐resistant epilepsy in children. Focal to bilateral tonic–clonic seizures (FBTCS) mark a high risk of drug‐resistant epilepsy and involve thalamocortical circuitry in their generation and propagation.

Protein Folding Mechanism of the Dimeric AmphiphysinII/Bin1 N-BAR Domain. [PDF]

open access: yesPLoS ONE, 2015
The human AmphyphisinII/Bin1 N-BAR domain belongs to the BAR domain superfamily, whose members sense and generate membrane curvatures. The N-BAR domain is a 57 kDa homodimeric protein comprising a six helix bundle.

An antibody that blocks human T-cell leukemia virus type 1 six-helix-bundle formation in vitro identified by a novel assay for inhibitors of envelope function

open access: yes, 2007
Fusion of the viral and cellular membranes is a critical step in the infection of cells by the human T-cell leukemia virus type 1 (HTLV-1) and this process is catalysed by the viral envelope glycoproteins.

Quantitative MRI Uncovers Subtle Cortical Damage in Myelin Oligodendrocyte Glycoprotein Antibody‐Associated Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To determine whether myelin‐sensitive quantitative MRI reveals microstructural abnormalities in normal‐appearing cortex (NACtx) in myelin oligodendrocyte glycoprotein antibody–associated disease (MOGAD), indicating that conventional MRI underestimates remission residual cortical injury.

The Potent Human Immunodeficiency Virus Type 1 (HIV-1) Entry Inhibitor HR212 Blocks Formation of the Envelope Glycoprotein gp41 Six-Helix Bundle [PDF]

open access: yesAIDS Research and Human Retroviruses, 2013
HR212, a recombinant protein composed of the heptad repeat, is a rationally designed human immunodeficiency virus type 1 (HIV-1) fusion inhibitor. This protein can be easily produced by Escherichia coli at a low cost.

Computer-Aided Approaches for Targeting HIVgp41

open access: yesBiology, 2012
Virus-cell fusion is the primary means by which the human immunodeficiency virus-1 (HIV) delivers its genetic material into the human T-cell host. Fusion is mediated in large part by the viral glycoprotein 41 (gp41) which advances through four distinct ...

Probing Sequence Dependence of Folding Pathway of α‑Helix Bundle Proteins through Free Energy Landscape Analysis

open access: yes, 2016
A comparative study on the folding of multiple three-α-helix bundle proteins including α3D, α3W, and the B domain of protein A (BdpA) is presented. The use of integrated-tempering-sampling molecular dynamics simulations achieves reversible folding and ...

Automatic Lesion Morphometrics Reliably Predict Sensorimotor Recovery After Spinal Cord Injury: A Longitudinal, Multicenter Neuroimaging Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To evaluate automatic magnetic resonance imaging (MRI)‐derived lesion morphometrics against manual measurements and their prognostic value for characterizing distinct acute to chronic neurological recovery trajectories after spinal cord injury (SCI). Methods We studied a retrospective, multicenter cohort of cervical and thoracolumbar
