Early-life vitamin A treatment rescues neonatal infection-induced durably impaired tolerogenic properties of celiac lymph nodes
Gut -draining mesenteric and celiac lymph nodes (mLNs and celLNs) critically contribute to peripheral tolerance toward food and microbial antigens by supporting the de novo induction of regulatory T cells (Tregs). These tolerogenic properties of mLNs and c ...
Cell Press2024Environmental determinants of access to shared sanitation in informal settlements: a cross-sectional study in Abidjan and Nairobi
Jérôme Chenal, Vitor Pessoa Colombo, Jürg Utzinger
Background Universal access to basic sanitation remains a global challenge, particularly in low- and middle-income countries. Efforts are underway to improve access to sanitation in informal settlements, often through shared facilities. However, access to ...
2023Risk assessment of waterborne virus in Lake Geneva: the present and the future
The presence of waterborne enteric viruses in lake recreational water sites is not desired, as they may have a negative impact on human health. However, their concentrations, fate and transport in lakes remain poor understood. To date, the health risks pos ...
2023Biofilm morphogenesis on soft hydrogels
Bacteria often colonize their environment in the form of surface attached multicellular communities called biofilms. Biofilms grow from surface-attached cells that undergo division while self-embedding in a viscoelastic matrix. Biofilms grow at the surface ...
EPFL2023In vitro synergistic action of TAT-RasGAP 317-326 peptide with antibiotics against Gram-negative pathogens
Objectives: Multidrug-resistant (MDR) bacteria are a continuously increasing threat for medicine, caus-ing infections recalcitrant to antibiotics. Antimicrobial peptides (AMPs) were identified as alternatives to antibiotics, being naturally occurring short ...
ELSEVIER SCI LTD2022Waterborne virus transport and the associated risks in a large lake
Tamar Kohn, Xavier Fernandez Cassi, Chaojie Li, Timothy R. Julian
Waterborne enteric viruses in lakes, especially at recreational water sites, may have a negative impact on human health. However, their fate and transport in lakes are poorly understood. In this study, we propose a coupled water quality and quantitative mi ...
2022Preexisting Heterogeneity of Inducible Nitric Oxide Synthase Expression Drives Differential Growth of Mycobacterium tuberculosis in Macrophages
John McKinney, Ophélie Rutschmann, Chiara Toniolo
Mycobacterium tuberculosis infection is initiated by the inhalation and implantation of bacteria in the lung alveoli, where they are phagocytosed by macrophages. Even a single bacterium may be sufficient to initiate infection. Thereafter, the clinical outc ...
AMER SOC MICROBIOLOGY2022Type 1 piliated uropathogenic Escherichia coli hijack the host immune response by binding to CD14
A key attribute of persistent or recurring bacterial infections is the ability of the pathogen to evade the host's immune response. Many Enterobacteriaceae express type 1 pili, a pre-adapted virulence trait, to invade host epithelial cells and establish pe ...
