Figure 3From: T cell receptor transgenic lymphocytes infiltrating murine tumors are not induced to express foxp3Expression of Foxp3EGFP in OTII transgenic mice. The relative percentages of Foxp3EGFP expression were comparable in splenocytes (SPL), lymph node lymphocytes (LN), and tumor-infiltrating lymphocytes (TIL) from control or B16-OVA-tumor-bearing OTII Foxp3EGFP mice. B16-OVA tumors were allowed to grow to 7-10 mm in diameter at which point they either did (closed square) or did not (open triangle) receive daily intraperitoneal injections of IL-2 for three days prior to analysis on the following day. In this cohort, mice did not all receive the same dose of IL2: the non-tumor bearing mouse received 250,000 units IL-2 per injection while mice in the tumor-bearing group received either 100 (one mouse), 250 (three mice), or 500 (one mouse) thousand units per injection.Back to article page
