Cloning and Functional Characterization of Novel Human Neutralizing Anti-IFN-α and Anti-IFN-β Antibodies.

Type I IFNs play a pivotal role in immune response modulation, yet dysregulation is implicated in various disorders. Therefore, it is crucial to develop tools that facilitate the understanding of their mechanism of action and enable the development of more effective anti-IFN therapeutic strategies. In this study, we isolated, cloned, and characterized anti-IFN-α and anti-IFN-β Abs from PBMCs of individuals treated with IFN-α or IFN-β, harboring confirmed neutralizing Abs.

Cloning and functional characterization of novel human neutralizing anti-interferon-alpha and anti-interferon-beta antibodies.

Type I interferons (IFNs) play a pivotal role in immune response modulation, yet dysregulation is implicated in various disorders. Therefore, it is crucial to develop tools that facilitate the understanding of their mechanism of action and enable the development of more effective anti-IFN therapeutic strategies. In this study, we isolated, cloned, and characterized anti-IFN-α and anti-IFN-β antibodies (Abs) from peripheral blood mononuclear cells of individuals treated with IFN-α or IFN-β, harboring confirmed neutralizing Abs.

Susceptibility to 3BNC117 and 10-1074 in ART suppressed chronically infected persons.

Objective: The aim of this study was to assess the susceptibility of HIV to two HIV monoclonal antibodies (bnAbs), 3BNC117 and 10-1074, in individuals with chronically antiretroviral therapy (ART) suppressed HIV infection.

Design: The susceptibility of bnAbs was determined using the PhenoSense mAb Assay, which is a cell-based infectivity assay designed to assess the susceptibility of luciferase-reporter pseudovirions. This assay is the only Clinical Laboratory Improvement Ammendment (CLIA)/College of American Pathologist (CAP) compliant screening test specifically developed for evaluating bnAb susceptibility in people with HIV infection.

The Hepatitis C Care Cascade During the Direct-Acting Antiviral Era in a United States Commercially Insured Population.

Background: Periodic surveillance of the hepatitis C virus (HCV) care cascade is important for tracking progress toward HCV elimination goals, identifying gaps in care, and prioritizing resource allocation. In the pre-direct-acting antiviral (DAA) era, it was estimated that 50% of HCV-infected individuals were diagnosed and that 16% had been prescribed interferon-based therapy. Since then, few studies utilizing nationally representative data from the DAA era have been conducted in the United States.

Non-invasive plasma glycomic and metabolic biomarkers of post-treatment control of HIV.

Non-invasive biomarkers that predict HIV remission after antiretroviral therapy (ART) interruption are urgently needed. Such biomarkers can improve the safety of analytic treatment interruption (ATI) and provide mechanistic insights into the host pathways involved in post-ART HIV control. Here we report plasma glycomic and metabolic signatures of time-to-viral-rebound and probability-of-viral-remission using samples from two independent cohorts.
