Contemporaneous SARS-CoV-2-Neutralizing Antibodies Mediated by N-glycan Shields

open access: yesViruses, 2023
Mutations and the glycosylation of epitopes can convert immunogenic epitopes into non-immunogenic ones via natural selection or evolutionary pressure, thereby decreasing their sensitivity to neutralizing antibodies.

The Effects of Birth Year, Age and Sex on Hemagglutination Inhibition Antibody Responses to Influenza Vaccination

open access: yesVaccines, 2018
The first exposure to influenza is thought to impact subsequent immune responses later in life. The consequences of this can be seen during influenza epidemics and pandemics with differences in morbidity and mortality for different birth cohorts.

Generation and selection of anti-flagellin monoclonal antibodies useful for serotyping Salmonella enterica [PDF]

open access: yes, 2013
In developing countries, bacterial acute gastroenteritis continues to be an important cause of morbidity and mortality among young children. Salmonellosis constitutes a major cause of infectious enteritis worldwide, most of them associated to the ...

HLA, Immune Response, and Susceptibility to COVID-19

open access: yesFrontiers in Immunology, 2021
The severe acute respiratory syndrome caused by Coronavirus 2 (SARS-CoV-2) that appeared in December 2019 has precipitated the global pandemic Coronavirus Disease 2019 (COVID-19).

Sequence Space Localization in the Immune System Response to Vaccination and Disease

open access: yes, 2003
We introduce a model of protein evolution to explain limitations in the immune system response to vaccination and disease. The phenomenon of original antigenic sin, wherein vaccination creates memory sequences that can \emph{increase} susceptibility to ...

Modelling original antigenic sin in dengue viral infection

open access: yesMathematical Medicine and Biology: A Journal of the IMA, 2017
Cross-reactive T cell responses induced by a primary dengue virus infection may contribute to increased disease severity following heterologous infections with a different virus serotype in a phenomenon known as the original antigenic sin. In this study, we developed and analyzed in-host models of T cell responses to primary and secondary dengue virus ...

Beta RBD boost broadens antibody-mediated protection against SARS-CoV-2 variants in animal models

open access: yesCell Reports Medicine, 2021
Summary: Severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) variants of concern (VOCs) with resistance to neutralizing antibodies are threatening to undermine vaccine efficacy.

Original antigenic sin with human bocaviruses 1–4

open access: yesJournal of General Virology, 2015
Human bocavirus (HBoV) 1 is a widespread parvovirus causing acute respiratory disease in young children. In contrast, HBoV2 occurs in the gastrointestinal tract and is potentially associated with gastroenteritis, whilst HBoV3 and -4 infections are less frequent and have not yet been linked with human disease.

Broadly Reactive IgG Responses to Heterologous H5 Prime-Boost Influenza Vaccination Are Shaped by Antigenic Relatedness to Priming Strains

open access: yesmBio, 2021
Prime-boost vaccinations of humans with different H5 strains have generated broadly protective antibody levels. However, the effect of an individual’s H5 exposure history on antibody responses to subsequent H5 vaccination is poorly understood.
