title: The dynamic changes of CD3e-CD11c+dendritic cells in spleens and bone marrow of mice infected with Schistosoma japonicum.
abstract: Schistosoma japonicum as a pathogeny requires dendritic cells to activate immune response. So, the research is to study the dynamic changes of CD3e-CD11c+dendritic cells in mice infected with S. japonicum. Zero, 7, 28, 35, and 63 days were selected to study the variation of dendritic cells, and the proportions of CD3e-CD11c+dendritic cells and CD86+mature dendritic cells in spleens and bone marrow were tested by flow cytometry. As a result, the variation trends of dendritic cells in spleen and bone marrow are similar as follows: the proportions of CD3e-CD11c+dendritic cells increased first and then decreased from day 35, but the percentages of CD86+mature dendritic cells decreased from day 28 and increased in day 63. In vitro, cultured dendritic cells treated with SEA and SAWA were tested by flow cytometry, the variation trends of CD86 on dendritic cells are consistent with the results in days 28 and 63. Besides CD86, the expression of MHC-II also hints immune regulation. In conclusion, it is speculated that dendritic cells play a role of immune regulation through MHC-II and CD86 in S. japonicum infection. Immune regulation of dendritic cells is not only in favor of the survival of host and parasite but also can be used in the therapy for immune diseases.
