We have studied the effects of recombinant human granulocyte colony-stimulating factor (rhG-CSF), hG macrophage-CSF (hGM-CSF), and gibbon interleukin-3 (gIL-3) on cell proliferation and differentiation in human long-term bone marrow culture (LTBMC). hG-CSF induced a maximal increase of 2.3-fold in both total nonadherent cells and GM cluster-forming cells, but only an increase of 1.7-fold in GM-...
Viral particles preferentially incorporate extra- and intracellular constituents of host cell lipid rafts, a phenomenon central to pseudotyping. Based on this mechanism, we have developed a system for the predictable decoration of enveloped viruses with functionally active cytokines that circumvents the need to modify viral proteins themselves. Human interleukin-2 (hIL-2), hIL-4, human granuloc...
Several lines of evidence indicate that transcriptional activation is coupled with DNA replication initiation, but the nature of initiation of DNA replication in mammalian cells is unclear. Polyoma virus replicon is an excellent system to analyze the initiation of DNA replication in murine cells because its replication requires an enhancer, and all components of replication machinery, except fo...
The high-affinity receptors for human interleukin-3 (IL-3), GM-CSF, and IL-5 are composed of alpha and beta subunits. The alpha subunits are primary ligand binding proteins specific for each ligand, whereas the three human receptors share a common beta subunit (beta c). In contrast to humans mice have two closely related genes, AIC2A and AIC2B, which are homologous to human beta c. The AIC2A ge...
The purified lectins from Lotus tetragonolobus and Dolichos biflorus were coupled to Sepharose 2B to make insoluble adsorbents for purification and fractionation of blood group A and H active glycoproteins. With both adsorbents, hog gastric mucin A + H blood substance (HGM), purified by phenol-ethanol precipitation, yielded fractions showing only A, only H, or AH activities. The AH fraction was...
When introduced in the 1990s, immunization with DNA plasmids was considered potentially revolutionary for vaccine development, particularly for vaccines intended to induce protective CD8 T cell responses against multiple antigens. We conducted, in 1997-1998, the first clinical trial in healthy humans of a DNA vaccine, a single plasmid encoding Plasmodium falciparum circumsporozoite protein (PfC...
Hierarchical linear models (HLMs) are a standard approach for analyzing data where individuals are measured repeatedly over time. However, such models are only applicable to longitudinal studies of Euclidean data. In this paper, we propose a novel hierarchical geodesic model (HGM), which generalizes HLMs to the manifold setting. Our proposed model explains the longitudinal trends in shapes repr...
