Abstract
The global prevalence of atopic diseases, including food allergy, is increasing and correlates with shifts in the commensal microbiota triggered by modern lifestyle factors. Current research focuses on the immunological mechanisms and microbial cues that regulate mucosal immunity and prevent allergic responses to food. We review the identification and characterization of novel antigen-presenting cell subsets that may be critical for the establishment and maintenance of tolerance to both food and intestinal bacteria. Microbially derived products, particularly from the Lachnospiraceae family of Clostridia, regulate intestinal homeostasis through a variety of mechanisms. Here, we highlight recent work on Clostridial metabolites and products that mediate protection against allergic responses to food.
期刊介绍：
Current Opinion in Immunology aims to stimulate scientifically grounded, interdisciplinary, multi-scale debate and exchange of ideas. It contains polished, concise and timely reviews and opinions, with particular emphasis on those articles published in the past two years. In addition to describing recent trends, the authors are encouraged to give their subjective opinion of the topics discussed.
In Current Opinion in Immunology we help the reader by providing in a systematic manner: 1. The views of experts on current advances in their field in a clear and readable form. 2. Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications.
Current Opinion in Immunology will serve as an invaluable source of information for researchers, lecturers, teachers, professionals, policy makers and students.
Current Opinion in Immunology builds on Elsevier''s reputation for excellence in scientific publishing and long-standing commitment to communicating reproducible biomedical research targeted at improving human health. It is a companion to the new Gold Open Access journal Current Research in Immunology and is part of the Current Opinion and Research(CO+RE) suite of journals. All CO+RE journals leverage the Current Opinion legacy-of editorial excellence, high-impact, and global reach-to ensure they are a widely read resource that is integral to scientists'' workflow.
