Figure 4.
Lymph node and spleen cells from A18 TCRtg mice vaccinated with the 5.4 construct, (thick lines), the control vector (thin lines), or untreated (shaded histograms) were analyzed (A) 3 d and (B) 15 d later by three-color FACS® analysis. The figure shows expression of CD44, CD62-L and CD69 (and BrdU labeling for day 3 after vaccination) on gated CD4 and Vβ8.3-positive T cells.
