Persistence of hepatitis A virus antibodies after primary immunization and response to revaccination in children and adolescents with perinatal HIV exposure

open access: yesRevista Paulista de Pediatria, 2015
OBJECTIVE: To assess possible factors associated with the loss of antibodies to hepatitis A 7 years after the primary immunization in children of HIV-infected mothers and the response to revaccination in patients seronegative for hepatitis A.

Detection of HIV-1 infection in dried blood spots from a 12-year-old ABO bedside test card [PDF]

open access: yes, 1998
Background and Objectives: We tested dried blood from an ABO bedside test card which had been stored at room temperature for 12 years, to prove that a patient with HIV-1 infection had been infected by blood transfusion. Materials and Methods: Immunoblots

Polyclonal B cell differentiation and loss of gastrointestinal tract germinal centers in the earliest stages of HIV-1 infection. [PDF]

open access: yesPLoS Medicine, 2009
The antibody response to HIV-1 does not appear in the plasma until approximately 2-5 weeks after transmission, and neutralizing antibodies to autologous HIV-1 generally do not become detectable until 12 weeks or more after transmission.

9G4+ antibodies isolated from HIV-infected patients neutralize HIV-1 and have distinct autoreactivity profiles. [PDF]

open access: yesPLoS ONE, 2013
Potent HIV-1 specific broadly neutralizing antibodies (BNA) are uncommon in HIV infected individuals, and have proven hard to elicit by vaccination. Several, isolated monoclonal BNA are polyreactive and also recognize self-antigens, suggesting a breach ...

Canonical Antibodies Adopt Distinct Binding Modes to Recognize Viral Glycan Shields. [PDF]

open access: yesAdv Sci (Weinh)
Canonical Y‐shaped antibodies recognize viral glycan shields through adaptive Fab assembly states shaped by glycan organization and somatic hypermutation. Structural analyses ofbroadly neutralizing antibodies VRC35 and VRC36 across glycoproteins of HIV‐1, influenza, SARS‐CoV‐2, and Lassa viruses reveal distinct Fab assembly states, spanning monovalent,

Genetic and immunological characterization of new subtype G envelope expressing HIV-1 pseudoviruses [PDF]

open access: yes, 2014
Includes bibliographical references.One of the greatest challenges for the development of an effective HIV-1 vaccine is the high genetic diversity of this pathogen and the complex escape mechanisms employed by the envelope gp120 and gp41 glycoprotein ...
