Summary of Meeting:
Recent studies have demonstrated the key role of mucosal defenses and immunoregulation in maintaining homeostasis in the distal intestine in concert with the commensal microbiota. This meeting discusses the latest information regarding the protective and effector innate and adaptive immune responses to the commensal intestinal microbiota that lead to mucosal homeostasis vs. chronic immune-mediated intestinal inflammation. We highlight the protective role of innate mucosal immune responses induced by ligation of toll- like receptors (TLR) to activate NF-kappaB and other signaling pathways. Mechanisms of bacterial killing by epithelial and phagocytic cells are explored. The interface of antigen presenting cell/ T cell activation leading to effector or regulatory T cell function in the intestine is examined with a particular emphasis on bacterial antigen-specific responses. Finally, biomedical applications of these basic research observations are explored. These basic and translational studies have direct implications for understanding the pathophysiology of chronic intestinal inflammation such as Crohn’s disease, ulcerative colitis and pouchitis and emphasize innate and adaptive immunoregulatory mechanisms that mediate mucosal homeostasis in a hostile environment. Major unresolved issues in mucosal immunology are as follows: (1) understanding how epithelial cells coexist with commensal intestinal bacteria, yet recognize the pathogenic organisms; (2) understanding how effector mechanisms in innate immune cells and T cells are appropriately downregulated; and (3) how understanding of basic immune regulation and inflammation can lead to the development of novel therapeutic agents for chronic inflammatory bowel diseases. This meeting presents state of the art lectures on the most recent research on innate, adaptive and regulatory immune responses to commensal bacteria, promotes interdisciplinary research interactions and explores several novel therapeutic approaches derived from recent pathogenic insights.

Keystone Symposia is offering scholarships of up to 1,200 USD to Students and Postdoctoral fellows. These scholarships are to be used to help defray the expenses associated with conference attendance, including airfare (restrictions may apply based on funding source), ground transportation, lodging costs, and a portion of meeting registration. Receipts will be required to receive reimbursement.

Abstracts submitted for poster presentation will be used as the basis for awarding the scholarships. Scholarship recipients will be selected based on the quality of science of the abstract and the relevance of the abstract to the conference topic. Only one application per abstract is accepted. Only one award per lab will be allocated.


To be eligible for a scholarship, you must be:

A graduate student or postdoctoral fellow currently enrolled in an academic institute at the start of the meeting for which you are applying. Note: a graduate student is defined as a student who is studying for a higher degree at an academic institution. A postdoctoral fellow is defined as an individual with a Ph.D., M.D., or DVM degree who is engaged in a temporary period of mentored research and/or scholarly training for the purpose of acquiring the professional skills needed to pursue their desired career path, and is within 6 years of these degrees.

Review Criteria

Criteria for Abstract Review:

  1. Relevance to the meeting topic
  2. Significance of the scientific question and results
  3. Style
    • Organization (e.g. the abstract has a clear beginning, middle and end)
    • Grammar and spelling
  4. Clarity of scientific presentations
    • Clear question or hypothesis
    • Sufficient background
    • The experimental approach and rationale for the approach are clear
    • The results are clearly presented
    • The interpretation and conclusions are reasonable and logical

Application Process

If you are eligible and wish to be considered for a scholarship, you should complete all of the following by the scholarship deadline for the meeting you wish to attend. It is recommended you begin these steps in advance of the deadline date to ensure completion.
