Awards and Grants

Inflammatory Bowel Disease

The Role of Microbial Metabolism in Food Intolerances associated with IBD (2022-2025)

Metabolism of Dietary Tryptophan by Intestinal Microbiota in IBD (2021-2025)

Role of Commensal Microbiota on Dietary Tryptophan Metabolism (2018-2019)

This grant was awarded to Dr. Alberto Caminero by The Biocodex Microbiota Foundation. This foundation is a non-profit which aids research in host-microbe interactions and pathologies related to the human microbiota. Support from this grant allowed for exploration into dietary tryptophan metabolism by gut microbiota and the ability of tryptophan metabolites to activate aryl hydrocarbon receptor.

Exploiting Intestinal Microbiota Dietary Protein Metabolism to Treat IBD (2018)

This grant is a start-up grant provided by the Douglas Family Chair of McMaster University. Funding from this grant has made it possible for Dr. Alberto Caminero to take on his role as an Assistant Professor. The grant also supported investigation in one of the research interests of the Caminero Lab, protein metabolism and IBD. 

Dr. Alberto Caminero collaborates with co-principal investigator Dr. Neeraj Narula (McMaster University) for this grant awarded by Crohn's and Colitis Canada. Using both wet lab and clinical research, this project focuses on various food intolerances present in ulcerative colitis and Crohns's disease patients. Collaborators on this grant include Prof. Detlef Schuppan (Harvard Medical School, USA; University of Mainz, Germany), Dr. Stephen M. Collins (McMaster University), and Dr. Elena F. Verdu (McMaster University). Learn more here.

This grant was awarded to Dr. Alberto Caminero by Canadian Institutes of Health Research. This project utilizes a variety of techniques including cell culture and gnotobiotic mouse models. Working together with co-principal investigator and metabolomics expert Dr. Harry Sokol (Sorbonne University, France), this project aims to learn more about the various targets of dietary tryptophan and how its metabolism can be altered by host microbiota. Collaborators on this grant include Dr. Stephen M. Collins (McMaster University), Dr. Elena F. Verdu (McMaster University), Dr. Giada De Palma (McMaster University), and Dr. Premysl Bercik (McMaster University). 

Food Allergy and Intolerance

Allergen Processing by Human Gastrointestinal Microbiota (2022)



Prevention of Peanut-Induced Anaphylaxis through Bacterial Metabolism (2020-2023)







Immunomodulation of Peanut-Induced Anaphylaxis Through Bacterial Metabolism (2021-2022)

Dr. Alberto Caminero serves as a co-principal investigator on this grant awarded by Nutricia Research Foundation. This foundation is an independent charity which supports young investigators in the field of nutrition and health. Alongside type 2 immunity and allergy researcher Dr. Rodrigo Jimenez-Saiz (McMaster University; National Center for Biotechnology, Spain), this grant investigates unknown roles of commensal bacteria in peanut allergy. 

This NSERC funded project awarded to Dr. Caminero explores the human gastrointestinal tract and its interaction with dietary allergens. Before interacting with the immune system, food allergens need to resist harsh conditions in the gut lumen such as low pH, bile acids, and digestive and microbial enzymes. While the gastrointestinal digestion of allergens by mammalian enzymes has been extensively characterized, the metabolic processing by human microbiota, and how this influences its ability to access the immune system, has yet to be elucidated. This project seeks to further our understanding of fundamental microbial processes involved in the metabolism of allergens. This will contribute to a better understanding of food allergies, which affect >2.5 million people in Canada.

Tri-agency Institutional Programs Canada awarded this grant to Dr. Alberto Caminero to learn more about the role of host-microbe interactions in peanut allergy. Techniques such as mouse monocolonizations and Ussing chambers give insight to the role of bacterial metabolism of peanut antigen into forms which more easily transverse the gut barrier. This project aims to reveal a role in bacterial metabolism to alter peanut immunogenicity. Collaborators for this project include co-principal investigator Dr. Rodrigo Jimenez-Saiz (McMaster University; National Center for Biotechnology, Spain), Dr. Yolanda R Carrasco (National Center for Biotechnology, Spain), Dr. Javier F. Moreno (Institute of Food Science Research-CIAL, Spain), Dr. Elena F. Verdu (McMaster University), Dr. Sarita U. Patil (Massachusetts General Hospital, USA), and Dr. Wayne G. Shreffler (Massachusetts General Hospital, USA). 

Funding for Equipment

Diet-microbiota Lab for Treatment of IBD and Food Sensitivities (2020-2023)

Funding from Canada Foundation for Innovation has allowed the Caminero Lab to purchase various exciting equipment to aid our present and future research. This equipment includes an anaerobic chamber, incubator, cell imaging system, ultra-performance liquid chromatography system, and more! We are very excited to move this equipment into our new lab space.
