摘要：

The transcriptional repressor protein BCL-6, implicated in the pathogenesis of B cell lymphoma, regulates lymphocyte differentiation and inflammation. We investigated the mechanism for the T helper cell subset 2 (T(H)2)-type inflammation that occurs in BCL-6(-/-) mice. Using chimeric mice we found that the T(H)2-type inflammation is dependent upon nonlymphoid cells. We identified three chemokines, MCP-1, MCP-3 and MRP-1,which are negatively regulated by BCL-6 in macrophages. Promoter analysis revealed that BCL-6 is a potent repressor of MCP-1 transcription. Our results provide a mechanism for the regulation of T(H)2-type inflammation by BCL-6 and link TH2 differentiation to innate immunity.
