Leslie Holsinger

Leslie found that the VAV exchange factor for rac was required for formation of the CAP or SMAC or immune synapse signaling complex on lymphocytes and also for T cell receptor signals to activate NFAT-dependent transcription and lead to T cell activation.. In addition, she used synthetic ligands to demonstrate that the SOS exchange factor could be activated by membrane proximity.
