title: Extracellular ATP induces phosphatidylserine externalization earlier than nuclear apoptotic events in thymocytes.
abstract: The present study shows for the first time that ATP(ec) induces a very early PS exposure in thymocytes and that this process can be induced in the absence of Ca(2+) influx and caspase activation.
