Abstract

It is well established that Peyer's patches (PPs) are sites for the differentiation of IgA plasma cell precursors, but molecular and cellular mechanisms in their trafficking remain to be elucidated. In this study, we show that alterations in type 1 sphingosine 1-phosphate (S1P) receptor expression during B cell differentiation in the PPs control the emigration of IgA plasma cell precursors. Type 1 S1P receptor expression decreased during the differentiation of IgM+B220+ B cells to IgA +B220+ B cells, but recovered on IgA+B220 - plasmablasts for their emigration from the PPs. Thus, IgA +B220- plasmablasts migrated in response to S1P in vitro. Additionally, IgA+ plasmablasts selectively accumulated in lymphatic regions of PPs when S1P-mediated signaling was disrupted by FTY720 treatment. This accumulation of IgA+ plasmablasts in the PPs led to their reduction in the intestinal lamina propria and simultaneous impairment of Ag-specific intestinal IgA production against orally administered Ag. These findings suggest that S1P regulates the retention and emigration of PP B cells and plays key roles in the induction of intestinal IgA production..
