Comparison of O-Antigen Gene Clusters of All O-Serogroups of Escherichia coli and Proposal for Adopting a New Nomenclature for O-Typing. [PDF]

open access: yesPLoS ONE, 2016
Escherichia coli strains are classified based on O-antigens that are components of the lipopolysaccharide (LPS) in the cell envelope. O-antigens are important virulence factors, targets of both the innate and adaptive immune system, and play a role in ...

Influence of DM-sensitivity on immunogenicity of MHC class II restricted antigens

open access: yesJournal for ImmunoTherapy of Cancer, 2021
Background Graft-versus-host-disease (GvHD) is a major problem in allogeneic stem cell transplantation. We previously described two types of endogenous human leukocyte antigen (HLA)-II restricted antigens depending on their behavior towards HLA-DM. While

The Structural Diversity of Carbohydrate Antigens of Selected Gram-Negative Marine Bacteria

open access: yesMarine Drugs, 2011
Marine microorganisms have evolved for millions of years to survive in the environments characterized by one or more extreme physical or chemical parameters, e.g., high pressure, low temperature or high salinity.

Systematic Chemoenzymatic Synthesis of O-Sulfated Sialyl Lewis x Antigens. [PDF]

open access: yes, 2015
O-Sulfated sialyl Lewis x antigens play important roles in nature. However, due to their structural complexity, they are not readily accessible by either chemical or enzymatic synthetic processes.

The HLA Ligandome Comprises a Limited Repertoire of O-GlcNAcylated Antigens Preferentially Associated With HLA-B*07:02

open access: yesFrontiers in Immunology, 2021
Mass-spectrometry based immunopeptidomics has provided unprecedented insights into antigen presentation, not only charting an enormous ligandome of self-antigens, but also cancer neoantigens and peptide antigens harbouring post-translational ...

Is indirect coombs test by pooled cells sufficient for antibody screening? An eye-opening case series

open access: yesGlobal Journal of Transfusion Medicine, 2023
The ideal way to screen for the presence of alloantibodies is by antibody screening panels which represent all clinically significant antigens in appropriate dosage.

Role of O-Acetylation in the Immunogenicity of Bacterial Polysaccharide Vaccines

open access: yesMolecules, 2018
The incidence of infectious diseases caused by several bacterial pathogens such as Haemophilus influenzae type b, Streptococcus pneumoniae, and Neisseria meningitidis, has been dramatically reduced over the last 25 years through the use of glycoconjugate

Questioning universal use of O– red blood cells in intrauterine transfusions

open access: yesAJOG Global Reports, 2023
In the setting of maternal alloimmunization to antigen(s) on fetal red blood cells, significant fetal anemia may develop, and an intrauterine transfusion may be required. When selecting a blood product for intrauterine transfusion, the priority should be
