Microbiological contamination of cosmetic products - observations from Europe, 2005-2018

Florentino Luciano Caetano Dos Santos

Background Although cosmetic products are not expected to be fully aseptic, their potential microbiological contamination might be dangerous, especially for immunocompromised patients. The extent of such contamination of cosmetics in Europe is poorly studi ...

Microbiota-Derived Lactate Activates Production of Reactive Oxygen Species by the Intestinal NADPH Oxidase Nox and Shortens Drosophila Lifespan

Bruno Lemaitre, Jean Philippe Boquete, Igor Iatsenko

Commensal microbes colonize the gut epithelia of virtually all animals and provide several benefits to their hosts. Changes in commensal populations can lead to dysbiosis, which is associated with numerous pathologies and decreased lifespan. Peptidoglycan ...

Absence of specific alternatively spliced exon of CD44 in macrophages prevents colitis

Ulrich Hoffmann, Riccardo Sabatini

CD44 is a transmembrane molecule appearing in numerous isoforms generated by insertions of alternatively spliced variant exons (CD44v) and having various binding partners. CD44v7 on T cells was proposed to promote colitis by preventing T-cell apoptosis. He ...

Reduction of Abeta amyloid pathology in APPPS1 transgenic mice in the absence of gut microbiota

Theo Lasser, Tristan Bolmont, Taoufiq Harach, Nicolas Jean Marc Antoine Duthilleul

Alzheimer’s disease is the most common form of dementia in the western world, however there is no cure available for this devastating neurodegenerative disorder. Despite clinical and experimental evidence implicating the intestinal microbiota in a number o ...

The microbiota provides colonisation resistance against intestinal helminths by regulating intestinal physiology

Luc Xavier Marie Lebon

Intestinal helminth infections are a global health problem affecting particularly people living in poor countries. Heavy worm burdens can lead to nutritional and cognitive deficiencies. Type-two immunity plays a crucial role in promoting tissue repair and ...

Microbiota Analysis Using an Illumina MiSeq Platform to Sequence 16S rRNA Genes

Nicola Harris, Alexis Rapin, Benjamin John Marsland, Céline Pattaroni

The microbiota have been shown to play an important role in diverse biological processes including immunity, metabolism, and digestion. Assessing the exact composition of the microbiota has proven challenging due to the often unknown growth specificities o ...

Oral application of Escherichia coli bacteriophage: safety tests in healthy and diarrheal children from Bangladesh

Patrick Descombes

A T4-like coliphage cocktail was given with different oral doses to healthy Bangladeshi children in a placebo-controlled randomized phase I safety trial. Fecal phage detection was oral dose dependent suggesting passive gut transit of coliphages through the ...

Association of brain amyloidosis with pro-inflammatory gut bacterial taxa and peripheral inflammation markers in cognitively impaired elderly

Tristan Bolmont, Taoufiq Harach

The pathway leading from amyloid-b deposition to cognitive impairment is believed to be a cornerstone of the pathogenesis of Alzheimer's disease (AD). However, what drives amyloid buildup in sporadic nongenetic cases of AD is still unknown. AD brains featu ...

miR-511-3p, embedded in the macrophage mannose receptor gene, contributes to intestinal inflammation

Michele De Palma, Mario Leonardo Squadrito

MiR-511-3p is embedded in intron 5 of the CD206/MRC1 gene Mrc1, expressed by macrophage and dendritic cell populations. CD206 and miR-511-3p expression are co-regulated, and their contribution to intestinal inflammation is unclear. We investigated their ro ...
