T cells don’t simply switch on—they reshape themselves. When these immune sentinels recognize a target, they rapidly reorganize their internal scaffolding to build an immunological synapse, a nanoscale interface that determines how strongly they respond. But that architectural overhaul needs brakes. Without them, T cells risk becoming hypersensitive, reacting to weak cues, and drifting toward autoimmunity. Now, new work reveals that one of those brakes—PTPN22 (proline-serine-threonine phosphatase–interacting protein 1)—acts not only on signaling molecules but also on the cytoskeletal machinery that sculpts the synapse itself.
