Combination of rRT-PCR and Anti-Nucleocapsid/Anti-Spike Antibodies to Characterize Specimens with Very Low Viral SARs-CoV-2 Load: A Real-Life Experience

Microorganisms, 2021
The objective of the present study was to evaluate the true positivity among people, whose results of initial testing of nasopharyngeal swabs (NPS) showed a very low viral load of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Impaired antibody response causes persistence of prototypic T cell-contained virus [PDF]

, 2009
CD8 T cells are recognized key players in control of persistent virus infections, but increasing evidence suggests that assistance from other immune mediators is also needed. Here, we investigated whether specific antibody responses contribute to control

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 ...

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 ...

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

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.

Cure of chronic viral infection and virus-induced type 1 diabetes by neutralizing antibodies [PDF]

, 2009
The use of neutralizing antibodies is one of the most successful methods to interfere with receptor–ligand interactions in vivo. In particular blockade of soluble inflammatory mediators or their corresponding cellular receptors was proven an effective ...

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 ...
