Dr. Alberto Caminero awarded the prestigious Basmajian Award for Excellence in Post-Doctoral Research Work

We are honoured to congratulate Dr. Alberto Caminero, Post-Doctoral Fellow in the Verdu lab, on being awarded the prestigious Basmajian Award for Excellence in Post-Doctoral Research Work. Dr. Caminero’s field of research focusses on bacterial metabolism of immunogenic dietary proteins, and how this activity contributes to the pathogenesis of chronic intestinal conditions. His work on wheat protein metabolism by commensal bacteria and opportunistic pathogens has been published in Gastroenterology. Other exciting work from his PDF is currently under second revision in Nature Communications.

The Basmajian Award for Excellence in Post-Doctoral Research Work was established to honour the the late Dr. John Basmajian. Dr Basmajian was an internationally renowned professor of medicine at McMaster University, recognized for his work in the development of rehabilitation science and in the mentorship of scientists. This annual award celebrates post-doctoral fellows at McMaster who have made meritorious contributions in research during their training.

Congratulations Dr. Caminero!

Microbial signals may predispose to pre-leukaemic changes

According to a new study in Nature by Meisel and Hinterleitner et al, signals from the gut microbiota may help induce a pre-leukemic state in individuals with genetic predisposition. Mutations, or deficiency in the gene tet methylcytosine dioxygenase 2 (TET2), occur with advancing age and are often present in patients with leukemia. However, only a proportion of individuals with this mutation, or mice that lack TET2, progress to a pre-leukemic state, suggesting that additional environmental factors are needed to drive disease. Using mice that lack the TET2 gene, researchers at the University of Chicago show that increased small intestinal permeability was present in mice that developed pre-leukemic changes. This “leaky gut” allowed the translocation of microbes, normally residing happily in the lumen of the small intestine, to tissues beyond the gut. Increased IL-6, a molecule that promotes inflammation and that is released following systemic bacterial dissemination, was critical for the development of the pre-leukemic state in TET2 deficient mice. However, antibiotic treatment aborted the pre-leukemic changes.Interestingly, once the TET2 deficient mice were derived and bred in germ-free conditions at the Axenic Gnotobiotic Unit in McMaster University, no changes in IL-6 were observed, and the pre-leukemic state failed to develop”, said Dr. Heather Galipeau, research associate in Dr. Verdu’s lab. “Maintaining intestinal barrier function could be critical for preventing a pre-leukemic state in genetically susceptible people, in order to restrict intestinal microbes to the gut. The study opens the way to potential new strategies aimed at strengthening the intestinal barrier or preventing systemic infections to reduce the progression to leukemia in individuals that have a genetic predisposition”, said Dr. Verdu, co-author of the study and Canada Research Chair in Diet, Microbiota and Intestinal Inflammation.

Two Farncombe members receive CIHR funding

We are happy to congratulate two amazing Farncombe researchers who were awarded 5 years of funding from CIHR in the recent announcement. Dr. Lesley MacNeil will study the role of environmental factors in neuronal aging and Dr. Waliul Khan will study  the interactions between serotonin signalling and autophagy in the context of gut inflammation. Excellent work!

He is an integral part of the Farncombe Institute,  actively collaborating with clinical research and directing the McMaster Metagenomic Facility.  Congratulations Dr. Surette on this honour!

Interview with Dr. Verdu is most viewed video at the GMFH World Summit 2017

As part of our commitment to knowledge dissemination and outreach on topics of GI health and disease, members such as Dr. Elena Verdu and her postdoc Heather Galipeau contribute regularly to Gut Microbiota for Health. GMFH is a website created by the European Society for Neurogastroenterology & Motility (ESNM) with the mission to share knowledge, create teaching materials and organize workshops on topics surrounding the gut microbiota and nutrition. As leader of the nutrition section of the site, Dr. Verdu organizes workshops for nutritionists and dieticians and is often asked to contribute to topic specific videos that appear on the site. One recent video on the topic of food sensitivities reached a wide audience and was the most viewed of all the videos from the GMFH Summit 2017 workshop. This is a great example of the important work that clinical and basic scientists in our Institute do to support good science communication with the public and health practitioners.

Congratulations to Miriam Bermudez Brito for her MITACS PDF award

Dr. Miriam Bermudez-Brito is post doctoral fellow with Dr. Elena Verdu. She obtained her PhD at the University of Granada in Spain and did a first postdoc at UMC Groningen and Top Institute of Food & Nutrition, in the Netherlands. The main focus of her research is to study the role of host-microbial interactions and gut proteolytic/anti-proteolytic balance that may affect development of sensitivity to food antigens and increase susceptibility to intestinal inflammatory conditions such as celiac disease and ulcerative colitis.

At McMaster, and supported by Mitacs Accelerate Program, Miriam will test the role of a probiotic bacterium B. longum NCC 2705 in the metabolism of dietary proteins that can cause dysregulated inflammatory reactions in the gut such as gluten and amylase trypsin inhibitors. Miria’s studies will enhance the mechanistic knowledge and provide a basis for human trials and a rational application of these probiotic strains together with the industrial partner, Nestle Research Center in Switzerland, in the prevention or treatment of food sensitivities.
