A Lipopolysaccharide O-Antigen Synthesis Gene in Mesorhizobium huakuii Plays Differentiated Roles in Root Nodule Symbiotic Compatibility with Astragalus sinicus

open access: yesMolecular Plant-Microbe Interactions, 2023
Lipopolysaccharide (LPS) is a ubiquitous microbial-associated molecular pattern. Plants can sense the three components of LPS, including core polysaccharide, lipid A, and O-antigen. LPS biosynthesis is an essential factor for the successful establishment

The Ongoing Journey of a Shigella Bioconjugate Vaccine

open access: yesVaccines, 2022
Shigellosis is a serious disease with a major impact, especially in low-income countries where mortality and morbidity are high. In addition, shigellosis among travelers and military personnel is a cause of significant morbidity and contributes to the ...

Characterization of the O antigen gene cluster and structural analysis of the O antigen of Francisella tularensis subsp. tularensis [PDF]

open access: yesJournal of Medical Microbiology, 2003
A gene cluster encoding enzymes involved in LPS O antigen biosynthesis was identified from the partial genome sequence of Francisella tularensis subsp. tularensis Schu S4. All of the genes within the cluster were assigned putative functions based on sequence similarity with genes from O antigen biosynthetic clusters from other bacteria.

Emerging Roles of the Unique Molecular Chaperone Cosmc in the Regulation of Health and Disease

open access: yesBiomolecules, 2022
The core-1 β1-3galactosyltransferase-specific chaperone 1 (Cosmc) is a unique molecular chaperone of core-1 β1-3galactosyltransferase(C1GALT1), which typically functions inside the endoplasmic reticulum (ER).

Enterobacterial Common Antigen: Synthesis and Function of an Enigmatic Molecule

open access: yesmBio, 2020
The outer membrane (OM) of Gram-negative bacteria poses a barrier to antibiotic entry due to its high impermeability. Thus, there is an urgent need to study the function and biogenesis of the OM.

Structural Studies of Shigella flexneri O-Antigens [PDF]

open access: yesEuropean Journal of Biochemistry, 1978
The structures of the O-antigens of all known serotypes and subserotypes of Shigella flexneri have been reinvestigated. The results support the assumption that these antigens are composed of a basic tetrasaccharide repeating unit (1), to which alpha-D-glucopyranosyl and/or O-acetyl groups are attached at different positions. Leads to 3)-beta-D-GlcNAcp-(

Specific selection of antigen-reactive lymphocytes into antigenically stimulated lymph nodes in sheep [PDF]

open access: yes, 1981
Sheep were primed to a variety of antigens and the efferent lymphatic from a popliteal lymph node was cannulated. The cannulated node was challenged repeatedly with PPD and all the lymph and cells removed from the animal.

Comparison of Shigella GMMA and glycoconjugate four-component formulations in animals

open access: yesFrontiers in Molecular Biosciences, 2023
Shigellosis is leading bacterial cause of diarrhea with high prevalence in children younger than 5 years in low- and middle-income countries, and increasing number of reports of Shigella cases associated to anti-microbial resistance.
