Abstract:
:The transcription factor c-Myb is expressed throughout T cell development in the thymus. However, little is understood about c-Myb function because of the embryonic lethality of traditional Myb-null mutations. Using tissue-specific deletion to abrogate c-Myb expression at distinct stages of T cell development, we identify three points at which c-Myb activity is required for normal T cell differentiation: transition through the double-negative 3 stage, survival of preselection CD4(+)CD8(+) thymocytes, and differentiation of CD4 thymocytes. Thus, c-Myb is essential at several stages during T cell development in the thymus.
