| abstractText | We demonstrated recently that, after accumulation of Ag-engaged B cells at the T cell zone boundaries in the spleen, these B cells migrate to the perimeter of follicles adjacent to the marginal zone. They undergo rapid proliferation at this site prior to coalescence into germinal centers (GCs). In this article, we report that this phase of migration and expansion of activated Ag-specific B cells, as well as subsequent formation of GCs, does not take place in the absence of splenic macrophages. Our data suggest a previously unappreciated function for macrophages in orchestrating the early phases of T cell-dependent B cell responses and formation of GCs distinct from their potential role in Ag presentation to T cells. |
