CD45 expression is essential for immunoglobulin (Ig)-mediated B cell activation. Treatments with either anti-Ig or anti-CD45 suggest that CD45 may facilitate early signaling events such as calcium mobilization, and phosphoinositide hydrolyis as well as later events leading to transcription of genes such as c-myc. To examine the role of CD45 more(More)
Genetically anemic SI/SI(d) mice have been shown previously to have a defective hematopoietic environment which prevents extensive erythroid differentiation of normal hematopoietic stem cells and also confers resistance to the erythroleukemia-inducing virus, Friend spleen focus-forming virus (SFFV). In this study, we show that the relative resistance of(More)
