Journal ArticleDOI
The Potential of Gut Commensals in Reinforcing Intestinal Barrier Function and Alleviating Inflammation
Kaisa Hiippala,Hanne Jouhten,Aki Ronkainen,Anna Hartikainen,Veera Kainulainen,Jonna Jalanka,Reetta Satokari +6 more
TL;DR: The latest findings considering the beneficial effects of the promising commensals across all major intestinal phyla are summarized, including the already well-known bifidobacteria, which use extracellular structures or secreted substances to promote intestinal health.
Journal ArticleDOI
Randomised clinical trial: faecal microbiota transplantation versus autologous placebo administered via colonoscopy in irritable bowel syndrome.
Perttu Lahtinen,Jonna Jalanka,Anna Hartikainen,Eero Mattila,Markku Hillilä,Jari Punkkinen,Jari Koskenpato,Veli-Jukka Anttila,Jyrki Tillonen,Reetta Satokari,Perttu Arkkila +10 more
TL;DR: Irritable bowel syndrome (IBS) has been associated with microbial dysbiosis, and the role of gut bacteria in IBS is still poorly understood.
Journal ArticleDOI
Minor Effect of Antibiotic Pre-treatment on the Engraftment of Donor Microbiota in Fecal Transplantation in Mice.
Tobias L. Freitag,Anna Hartikainen,Hanne Jouhten,Cecilia Sahl,Seppo Meri,Veli-Jukka Anttila,Eero Mattila,Perttu Arkkila,Jonna Jalanka,Reetta Satokari +9 more
TL;DR: Pre-treatment with broad-spectrum antibiotics did not improve the overall engraftments of donor microbiota, but did improve the engraftment of specific taxa.
Journal ArticleDOI
Black Queen Evolution and Trophic Interactions Determine Plasmid Survival after the Disruption of the Conjugation Network.
Johannes Cairns,Katariina Koskinen,Reetta Penttinen,Tommi Patinen,Anna Hartikainen,Roosa Jokela,Liisa Ruusulehto,Sirja Viitamäki,Sari Mattila,Teppo Hiltunen,Teppo Hiltunen,Matti Jalasvuori,Matti Jalasvuori +12 more
TL;DR: Results show that outcomes of attempts to resensitize bacterial communities by disrupting the conjugation network are highly dependent on ecological factors and resistance mechanisms.
Journal ArticleDOI
Colonic Gene Expression and Fecal Microbiota in Diarrhea-predominant Irritable Bowel Syndrome: Increased Toll-like Receptor 4 but Minimal Inflammation and no Response to Mesalazine.
Jonna Jalanka,Ching Lam,Andrew J. Bennett,Andrew J. Bennett,Anna Hartikainen,Fiona Crispie,Laura Finnegan,Paul D. Cotter,Robin C. Spiller +8 more
TL;DR: The effect of mesalazine on inflammatory gene expression and microbiota composition in IBS-D has been previously associated with evidence of immune activation and altered microbiota using 16S ribosomal RNA sequencing as discussed by the authors.
