Dissecting HIV Virulence: Heritability of Setpoint Viral Load, CD4+ T Cell Decline and Per-Parasite Pathogenicity

Pathogen strains may differ in virulence because they attain different loads in their hosts, or because they induce different disease-causing mechanisms independent of their load. In evolutionary ecology, the latter is referred to as" per-parasite pathogen ...

Elevated HLA-A expression impairs HIV control through inhibition of NKG2A-expressing cells

Jacques Fellay

The highly polymorphic human leukocyte antigen (HLA) locus encodes cell surface proteins that are critical for immunity. HLA-A expression levels vary in an allele-dependent manner, diversifying allele-specific effects beyond peptide-binding preference. Ana ...

HLA-B*14:02-Restricted Env-Specific CD8+ T-Cell Activity Has Highly Potent Antiviral Efficacy Associated with Immune Control of HIV Infection

Jacques Fellay

Immune control of human immunodeficiency virus type 1 (HIV) infection is typically associated with effective Gag-specific CD8+ T-cell responses. We here focus on HLA-B14, which protects against HIV disease progression, but the immunodominant HLA-B14-rest ...

Single-Virus Droplet Microfluidics for High-Throughput Screening of Neutralizing Epitopes on HIV Particles

Christoph Merten

Analyzing surface epitopes of single HIV particles holds great potential for the development of vaccine candidates. However, existing technologies do not allow corresponding screens at high throughput. We present here a single-virus droplet-based microflui ...

No Evidence for Association of beta-Defensin Genomic Copy Number with HIV Susceptibility, HIV Load during Clinical Latency, or Progression to AIDS

Jacques Fellay

Common single-nucleotide variation in the host accounts for 25% of the variability in the plasma levels of HIV during the clinical latency stage (viral load set point). However, the role of rare variants and copy number variants remains relatively unexplor ...

Site-Specific Polymer Attachment to HR2 Peptide Fusion Inhibitors against HIV-1 Decreases Binding Association Rates and Dissociation Rates Rather Than Binding Affinity

Harm-Anton Klok, Frederik Roman Wurm, Maarten Danial

A popular strategy for overcoming the limited plasma half-life of peptide heptad repeat 2 (HR2) fusion inhibitors against HIV-1 is conjugation with biocompatible polymers such as poly(ethylene glycol) (PEG). However, despite improved resistance to proteoly ...

Estimating the Respective Contributions of Human and Viral Genetic Variation to HIV Control

Jacques Fellay, Amalio Telenti, Istvan Bartha

We evaluated the fraction of variation in HIV-1 set point viral load attributable to viral or human genetic factors by using joint host/pathogen genetic data from 541 HIV infected individuals. We show that viral genetic diversity explains 29% of the variat ...

Single particle maximum likelihood reconstruction from superresolution microscopy images

Suliana Manley, Julia Gunzenhäuser

Point localization superresolution microscopy enables fluorescently tagged molecules to be imaged beyond the optical diffraction limit, reaching single molecule localization precisions down to a few nanometers. For small objects whose sizes are few times t ...

Evaluating the Impact of Functional Genetic Variation on HIV-1 Control

Jacques Fellay, Istvan Bartha

Previous genetic association studies of human immunodeficiency virus-1 (HIV-1) progression have focused on common human genetic variation ascertained through genome-wide genotyping. ...

The memristive effect as a novelty in drug monitoring

Giovanni De Micheli, Sandro Carrara, Ioulia Tzouvadaki, Nima Aliakbarinodehi

Nanoscale devices exhibiting memristive properties show great potential in a plethora of applications. In this work, memristive nanowires are presented for the first time as ideal candidates for absolutely novel, ultrasensitive, highly specific and selecti ...
