Abstract: |
Intercellular communication is essential for coordinating a successful immune response. The immunological synapse provides a platform for such communication by coupling activated lymphocytes specifically to their target cells. The formation of an IS in T cells is triggered by stimulation of the T cell antigen receptor and depends on the rapid and polarized remodeling of the cytoskeleton. This dramatic change in cell polarity is required to achieve optimal T cell activation and function. In this chapter, we will discuss the structure of the IS, how it forms, and how it contributes to T cell function during immune responses. © Springer International Publishing Switzerland 2015. |
