Multiple intercellular contacts give rise to the complex systems behavior of
the immune system. We are extending our imaging systems in order to study
interactions amongst a variety of T cell partners such as dendritic cells and
macrophages. Of particular interest are the multipartite interactions in
which three or more cells come together simultaneously or sequentially to
create complex biology. Novel biological insights can be gleaned by
understanding the nature of cooperative and competitive cellular interactions. In addition, we are using molecular genetics coupled with imaging to identify novel molecular players recruited to immune cell-cell interfaces. Our ultimate goal is to uncover the methods by which the immune system regulates the decision between tolerance and immunity
