mRNA expression profiles of mDia isoforms in DCs. The mRNA expression profiles of mDia isoforms, mDia1, mDia2, and mDia3, in BMDCs from B6 and mDia1^−/− mice stimulated with (+) or without (−) LPS, and LCs, dermal DCs, splenic DCs, and CD4⁺ T cells from B6 mice. Data are expressed as the amounts of mRNA relative to that of glyceraldehyde-3-phosphate dehydrogenase (GAPDH). Data are mean ± SD (n = 3) of 3 independent experiments. n.d. indicates not dectected. *P < .05 vs corresponding B6 mice.
