Pure populations of in vitro propagated bone marrow-derived macrophages are constitutively Ia negative. Co-culturing of these cells with recombinant interferon-gamma (rIFN-gamma) resulted in the appearance of high amounts of Ia antigens at the cell surface of essentially all cells. The continuous presence of the stimulus was a prerequisite for sustained Ia(More)
Digit span (DS) and visual memory span (VMS) tasks have been shown to be distinct in young children but fail to show modality specificity in older American children and adults (Fastenau, Conant, & Lauer, 1997, 1998). The present study examines the possibility that processing of VMS becomes automatized with written language training. In a sample of 139(More)
The antigen-mediated activation of a number of T cell clones by bone marrow (BM) cells cultivated in the presence of various colony-stimulating factor (CSF) preparations was investigated. BM macrophages (BMM phi) grown in L929 cell supernatant as a crude source of macrophage colony-stimulating factor (M-CSF) as well as BM cells propagated in the presence of(More)
Biosynthetic properties of Ia antigens derived from B cells, from T cell clone BK-BI-2.6.C6 and from rIFN-gamma induced bone marrow macrophages (BMMO) were evaluated before and after translation. Gross features of B and T cell Ia were found to be very similar. At the pretranslational level no obvious differences were noticed. Following translation in both(More)
