Phenotypic characterization of gamma interferon-induced human monocyte polykaryons.
Multinucleated giant cells of mononuclear phagocyte origin (monocyte or macrophage polykaryons [MPs] ) are seen in numerous different normal and pathologic states. We have previously shown that gamma interferon (IFN-gamma) induces fusion of uninuclear monocytes (UMs) to form MPs. This study was designed to characterize these IFN-gamma-induced MPs. Control and IFN-gamma-treated UMs and MPs did n...
متن کاملInducible Expression of Human Gamma Interferon
Background:The premature termination of high producer clones, which will be killed due to cell proliferation and proteins production antagonism, is one of the basic drawback in recombinant proteins technology. Furtheremore, it is supposed some toxic proteins like interferon which we intended to clone and express, inhibit host cells’ proliferation. So, it is necessary to tightly control IFN-γ pr...
متن کاملInterrelationships of human interferon-gamma with lymphotoxin and monocyte cytotoxin
Crude preparations of interferon (IFN)-gamma derived from human peripheral blood leukocyte (PBL) cultures induced with 12-O-tetra-decanoylphorbol-13-acetate (TPA) and phytohemagglutinin (PHA) were more cytotoxic to HeLa cells than partially purified nautral or highly purified recombinant human IFN-gamma preparations. Conditioned media from PBL cultures contained, in addition to IFN-gamma, a mix...
متن کاملPreparation and characterization of recombinant DNA-derived human interferon-gamma.
An attempt was made to prepare a highly purified, active recombinant DNA-derived human interferon-gamma. When the protein was denatured in urea and refolded, gel filtration and sedimentation velocity experiments indicated the presence of two forms, which are different in size and are not in a rapid reversible equilibrium. The two forms could be chromatographically separated. Far-UV circular dic...
