Aim: Located in the Southwest Indian Ocean area (SIOA), the two French overseas territories (FOTs) of Reunion and Mayotte islands are heavily impacted by antimicrobial resistance. The aim of this study was to investigate all cases of NDM-5 and OXA-181 carbapenemase-producing Escherichia coli (CPEc) in these two FOTs between 2015 and 2020, to better understand the regional spread of these last-line treatment resistant bacteria.
Methods: All E.

Autoimmune liver diseases (AILD) involve dysregulated CD4 T cell responses against liver self-antigens, but how these autoreactive T cells relate to liver tissue pathology remains unclear. Here we perform single-cell transcriptomic and T cell receptor analyses of circulating, self-antigen-specific CD4 T cells from patients with AILD and identify a subset of liver-autoreactive CD4 T cells with a distinct B-helper transcriptional profile characterized by PD-1, TIGIT and HLA-DR expression. These cells share clonal relationships with expanded intrahepatic T cells and exhibit transcriptional signatures overlapping with tissue-resident T cells in chronically inflamed environments.

Motivation: T-cell receptors (TCRs) elicit and mediate the adaptive immune response by recognizing antigenic peptides, a process pivotal for cancer immunotherapy, vaccine design, and autoimmune disease management. Understanding the intricate binding patterns between TCRs and peptides is critical for advancing these clinical applications. While several computational tools have been developed, they neglect the directional semantics inherent in sequence data, which are essential for accurately characterizing TCR-peptide interactions.

An efficient in vitro propagation protocol has been established for a valuable medicinal plant, Salix tetrasperma using mature nodal explants. The investigation aimed to observe the influence of various combinations and concentrations of cytokinins (mT, BA, and Kn) and auxins (NAA, IAA, and IBA) on regeneration potential using the Murashige and Skoog (MS) medium. Among individual cytokinin treatments, 5.

International travel facilitates the acquisition and carriage of extended-spectrum beta-lactamase-producing Escherichia coli (ESBL-E). We describe genomes of predominant ESBL-E clones detected before and after travel among subjects departing from Rio de Janeiro, Brazil, during 2015-2021, and genomes publicly available from countries visited by travelers. WGS (Illumina NovaSeq) was performed on 70 ESBL-E isolates from 66 travelers (18 pre- and 52 post-travel).
