Regulation of T cell expansion by antigen presentation dynamics [PDF]
PNAS 2019, 116 (13) 5914-5919, 2018 An essential feature of the adaptive immune system is the proliferation of antigen-specific lymphocytes during an immune reaction to form a large pool of effector cells. This proliferation must be regulated to ensure an effective response to infection while avoiding immunopathology.

Frontiers in Microbiology, 2023 Human rotaviruses attach to histo-blood group antigens glycans and null alleles of the ABO, FUT2 and FUT3 genes seem to confer diminished risk of gastroenteritis. Yet, the true extent of this protection remains poorly quantified.

Genetic Diversity and Histo-Blood Group Antigen Interactions of Rhesus Enteric Caliciviruses [PDF]
Journal of Virology, 2010 ABSTRACTRecently, we reported the discovery and characterization of Tulane virus (TV), a novel rhesus calicivirus (CV) (T. Farkas, K. Sestak, C. Wei, and X. Jiang, J. Virol.82:5408-5416, 2008). TV grows well in tissue culture, and it represents a new genus withinCaliciviridae, with the proposed name ofRecovirus. We also reported a high prevalence of CV

Epigenomics‐guided precision oncology: Chromatin variants in prostate tumor evolution
International Journal of Cancer, EarlyView.Abstract Prostate cancer is a common malignancy that in 5%–30% leads to treatment‐resistant and highly aggressive disease. Metastasis‐potential and treatment‐resistance is thought to rely on increased plasticity of the cancer cells—a mechanism whereby cancer cells alter their identity to adapt to changing environments or therapeutic pressures to create

A post-translational modification of human Norovirus capsid protein attenuates glycan binding
Nature Communications, 2019 Attachment of human noroviruses to histo blood group antigens (HBGAs) is essential for infection. Here the authors report that an asparagine residue located near the HBGA-attachment site can convert into an iso-aspartate residue through spontaneous ...

Low Levels of Natural Anti-α-N-Acetylgalactosamine (Tn) Antibodies Are Associated With COVID-19
Frontiers in Microbiology, 2021 Human serum contains large amounts of anti-carbohydrate antibodies, some of which may recognize epitopes on viral glycans. Here, we tested the hypothesis that such antibodies may confer protection against COVID-19 so that patients would be preferentially

The effects of symmetry on the dynamics of antigenic variation [PDF]
J. Math. Biol. 66, 115-137 (2013), 2012 In the studies of dynamics of pathogens and their interactions with a host immune system, an important role is played by the structure of antigenic variants associated with a pathogen. Using the example of a model of antigenic variation in malaria, we show how many of the observed dynamical regimes can be explained in terms of the symmetry of ...

Norovirus–host interaction: Multi-selections by human histo-blood group antigens [PDF]
Trends in Microbiology, 2011 The discovery of human histo-blood group antigens (HBGAs) as receptors or ligands of noroviruses (NoVs) raises a question about the potential role of host factors in the evolution and diversity of NoVs. Recent structural analysis of selected strains in the two major genogroups of human NoVs (GI and GII) demonstrated highly conserved HBGA binding ...

Aging Cell, EarlyView.Multi‐ciliated cells in the infundibulum and ampulla (INF/AMP) epithelium are vacuolated in aging. Unique cellular susceptibility of the INF/AMP epithelial population and aging‐associated decline in ovarian artery circulation, which supports the ovary and INF/AMP, contribute to this region‐specific vacuolation phenotype, as a consequence of a mildly ...

Individuals with Le(a+b-) blood group have increased susceptibility to symptomatic vibrio cholerae O1 infection. [PDF]
PLoS Neglected Tropical Diseases, 2011 Human genetic factors such as blood group antigens may affect the severity of infectious diseases. Presence of specific ABO and Lewis blood group antigens has been shown previously to be associated with the risk of different enteric infections.
