TLDR
The ability of HuMiX to recapitulate in vivo transcriptional, metabolic and immunological responses in human intestinal epithelial cells following their co-culture with the commensal Lactobacillus rhamnosus GG (LGG) grown under anaerobic conditions is demonstrated.Abstract:
We thank the scientists and technical staff of the Luxembourg Centre for Systems Biomedicine and Center for Applied Nanobioscience and Medicine, particularly Matthew Barrett and Brett Duane for their excellent technical assistance and engineering support We are grateful to Francois Bernardin, Nathalie Nicot and Laurent Vallar for the microarray analysis; Aidos Baumuratov for imaging support; Linda Wampach for HuMiX illustrations; and Anna Heintz-Buschart for fruitful discussions This work was supported by an ATTRACT programme grant (ATTRACT/A09/03), a CORE programme grant (CORE/11/BM/1186762), a European Union Joint Programming in Neurodegenerative Diseases grant (INTER/JPND/12/01) and a Proof-of-Concept grant (PoC-15/11014639) to PW, Accompany Measures mobility grant (12/AM2c/05) to PW and PS, an INTER mobility grant to PS (INTER/14/7516918), and an Aide a la Formation Recherche (AFR) postdoctoral grant (AFR/PDR 2013-1/BM/5821107) as well as a CORE programme grant (CORE/14/BM/8066232) to JVF, all funded by the Luxembourg National Research Fund (FNR) This work was further supported by a grant attributed to CS-D by the 'Fondation Recherche sur le SIDA du Luxembourg' Bioinformatics analyses presented in this paper were carried out in part using the HPC facilities of the University of Luxembourg (http://hpcunilu)read more

Versatile human in vitro triple coculture model coincubated with adhered gut microbes reproducibly mimics pro-inflammatory host-microbe interactions in the colon
Annelore Beterams,Kim De Paepe,Laure Maes,India Jane Wise,Herlinde De Keersmaecker,Andreja Rajkovic,Debby Laukens,Tom Van de Wiele,Marta Calatayud Arroyo +8 more
TL;DR: In this paper, the authors developed and characterized a broadly applicable, easy-to-handle in vitro triple coculture model that combines chemically-induced macrophage-like, goblet and epithelial cells covered by a mucus layer, which can be coincubated with complex human-derived gut microbiota samples for 16 hours.

Linear Models and Empirical Bayes Methods for Assessing Differential Expression in Microarray Experiments
TL;DR: The hierarchical model of Lonnstedt and Speed (2002) is developed into a practical approach for general microarray experiments with arbitrary numbers of treatments and RNA samples and the moderated t-statistic is shown to follow a t-distribution with augmented degrees of freedom.
