In Vivo Emergence of HIV-1 Highly Sensitive to Neutralizing Antibodies [PDF]

, 2011
Background: The rapid and continual viral escape from neutralizing antibodies is well documented in HIV-1 infection. Here we report in vivo emergence of viruses with heightened sensitivity to neutralizing antibodies, sometimes paralleling the development

Protective mechanisms of nonneutralizing antiviral antibodies.

PLoS Pathogens, 2023
Antibodies that can bind to viruses but are unable to block infection in cell culture are known as "nonneutralizing antibodies." Such antibodies are nearly universally elicited following viral infection and have been characterized in viral infections ...

Behaviour of non-donor specific antibodies during rapid re-synthesis of donor specific HLA antibodies after antibody incompatible renal transplantation [PDF]

, 2013
Background: HLA directed antibodies play an important role in acute and chronic allograft rejection. During viral infection of a patient with HLA antibodies, the HLA antibody levels may rise even though there is no new immunization with antigen ...

SIGNIFICANCE OF BIVALENCE OF ANTIBODY IN VIRAL NEUTRALIZATION [PDF]

The Journal of Experimental Medicine, 1971
The role of bivalence of antibody in its capacity to neutralize virus was studied with rabbit antibodies to the bacteriophage, ϕX174. Univalent Fab or Fab' fragments of IgG isolated from antiviral antisera obtained early in the immunization schedule had virtually no activity compared to that of the intact IgG.

Antibodies Are Not Essential for the Resolution of Primary Cytomegalovirus Infection but Limit Dissemination of Recurrent Virus [PDF]

, 1994
Virus shedding from the epithelial cells of the serous acini of salivary glands is a major source for the horizontal transmission of cytomegalovirus. These cells are, different to other tissues, exempt from CD8 T lymphocyte control. CD4 T lymphocytes are

Antibody response against selected epitopes in the HIV-1 envelope gp41 ectodomain contributes to reduce viral burden in HIV-1 infected patients

Scientific Reports, 2021
The ectodomain of gp41 is the target of potent binding and neutralizing antibodies (NAbs) and is being explored in new strategies for antibody-based HIV vaccines. Previous studies have suggested that the W164A-3S (3S) and EC26-2A4 (EC26) peptides located

Antibody barriers to going viral [PDF]

Journal of Experimental Medicine, 2019
Antibody neutralization of a virus in vitro is often associated with protection against viral exposure in vivo, but the mechanisms operational in vivo are often unclear. By investigating a large number of antibodies, Earnest et al. (https://doi.org/10.1084/jem.20190736) show the importance of antibody effector function in neutralizing antibody ...

The Vestigial Esterase Domain of Haemagglutinin of H5N1 Avian Influenza A Virus: Antigenicity and Contribution to Viral Pathogenesis

Vaccines, 2018
Initial attempts to develop monoclonal antibodies as therapeutics to resolve influenza infections focused mainly on searching for antibodies with the potential to neutralise the virus in vitro with classical haemagglutination inhibition and ...

Production of the Receptor-binding Domain of the Viral Spike Proteins from 2003 and 2019 SARS CoVs and the Four Common Human Coronaviruses for Serologic Assays and Inhibitor Screening

Bio-Protocol, 2021
The recombinant receptor-binding domain (RBD) of the viral spike protein from SARS-CoV-1 and 2 are reliable antigens for detecting viral-specific antibodies in humans.

Antibody therapies for the prevention and treatment of viral infections

npj Vaccines, 2017
Antibodies are an important component in host immune responses to viral pathogens. Because of their unique maturation process, antibodies can evolve to be highly specific to viral antigens.
