Hyperactivation of the transcription factor Stat5 leads to various leukemias. Stat5 activity is regulated by the protein phosphatase SHP-1 in a phospholipase C (PLC)-β3-dependent manner. Thus, PLC-β3-deficient mice develop myeloproliferative neoplasm, like Lyn (Src family kinase)- deficient mice. Here we

To study the potential roles of CD40L in immune responses, we generated CD40L-deficient mice by gene targeting. Similar to the effects of CD40L mutations in humans (hyper-IgM syndrome), CD40L-deficient mice have a decreased IgM response to thymus-dependent antigens, fail altogether
