Abstract

Inflammatory bowel diseases are disorders that affect millions of people worldwide. The inflammatory process in these diseases involves innate and adaptive immunity and also an influence of gut microbiota. NKT cells are a distinct subtype of T lymphocytes which play a role in intestinal mucosal immunity in experimental models of colitis. Studies regarding the role of NKT cells, gut microbiota and the inflammatory process in colitis are still scarce. Therefore, our project aims to relate the influence of gut microbiota in the profile of NKT cells during colitis and how such change may affect inflammation. Thus, we will use an experimental model of DSS-induced colitis to assess the role of NKT cells in colitis and the influence of changing gut microbiota in the profile of these cells. We will analyze the profile of cytokines and chemokines involved in this model, the phenotype of NKT cells through flow cytometry, histology of intestinal tissue and changes in microbiota. (AU)
