Signal transmission through MHC class II molecules in a human B lymphoid progenitor cell line: different signaling pathways depending on the maturational stages of B cells.

abstract：:In malignant B lymphoma cells interleukin-10 (IL-10) expression is frequently upregulated. This effect is thought to support to the malignant transformation of these cells and to be a potential target for pharmacotherapy. To define better the mechanism for upregulation of the IL-10 gene, we tested the association betw...
