Clustering of membrane proteins is essential for signaling by T lymphocytes and neurons and in both cases depends on the transit of membrane microdomains across the plane of the cell surface. Khan et al. show that agrin, a protein required for organization of the neuromuscular synapse, is also expressed in T cells and influences the formation of the immune synapse. Addition of purified agrin to T cell cultures or enhancement of clustering with an antibody to agrin significantly lowered the threshold of antigen responsiveness by T cells. Thus, the modes for information delivery between lymphocytes and neurons may be more closely related than previously anticipated. See the Perspective by Trautmann and Vivier for more details.
