A03: Summary

Several adenine nucleotides (AN) have been identified as Ca2+ mobilizing 2nd messengers in immune cells. CD38 is, at least in part, responsible for their formation and interconversion, and initial results suggest a role of CD38 in systemic and intestinal inflammation. The aim of the project is to unravel the role of AN in T cell function. Therefore, we will investigate T cells deficient in different AN-activated Ca2+ channels in vitro and in vivo in mouse models for intestinal inflammation. We expect that our study will clarify the function of distinct AN and their target ion channels in T cell differentiation and function particularly in the intestine.
