FIGURE 4. ERK activation during positive selection in T cell-specific RASA1-deficient AND TCR Tg mice.
Representative flow cytometric plots showing expression of phospho-ERK in the indicated thymocyte populations from littermate rasa1fl/fl and rasa1fl/fl plck-cre AND TCR Tg mice (see Fig. 3). Numbers represent the percent phospho-ERK+ cells within each population. The same results were obtained in a repeat experiment.
