Figure 7 The number of Treg cells in the lung after the transfer of LPS-BMDCs into OVA-induced asthmatic mice. Pulmonary Tregs were characterized as CD4+CD25+Foxp3+ by flow cytometry. The number of Tregs was not significantly different among groups. (A) Schematic of the OVA-induced asthmatic mouse model. (B) Number of pulmonary Tregs.
