Modulation of LAP+ CD4 T cells following anti-LAP remedy(A) Frequency of LAP+ T cells in na e and anti-LAP or IC treated B16 melanoma-bearing mice. Mice were treated with anti-LAP clone TW7-28G11 and LAP+ T cells measured with a non-competing anti-LAP clone (TW7-16B4) by flow cytometry in spleen (n=8), dLN and tumor (n=5). Data are from at least 3 independent experiments. (B) Active TGF- release from P3U1 cells expressing mouse LAP/TGF-, treated with anti-LAP clones TW7-16B4 and TW7-28G11 or IC, measured by ELISA (n=3); for more particulars see Materials and Methods.

Representative histograms of proliferation of responder CD4+ T cells (F) and percent suppression (G) are shown. Foxp3+ cells served as controls. Indicated samples have been treated with TGF- receptor inhibitor (TGFBRI), DMSO handle, anti-TGF- or IC antibody (n=41; combined data from four experiments, normalized to the amount of suppression of LAP+ cells in spleen).Formula of 2-Fluoro-4-methyl-5-nitrobenzonitrile Error bars, mean .Price of 5-Iodobenzo[b]thiophene e.PMID:23398362 m.
