FIG. 6.

TCR stimulation induces STAT3 phosphorylation in HSV-infected T cells. Jurkat T cells were incubated with mock- or HSV-infected fibroblasts and removed. T cells were TCR stimulated, fixed, and permeabilized. T cells were stained with phospho-specific antibodies against the transcription factors STAT1 (Ser727), STAT1 (Tyr705), and STAT3. The histogram plots depicted are representative of four independent flow cytometry experiments each. Plots of the mean fluorescence intensities from these experiments are depicted in the bar graphs on the right. *, P < 0.05, Student's t test.
