Interrelationships 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 کاملGamma interferon and lymphotoxin, released by activated T cells, synergize to inhibit granulocyte/monocyte colony formation
We have shown that lymphocytes stimulated by PHA produce colony-forming unit of granulocyte/monocyte (CFU-GM)-stimulating and -inhibiting activities, IFN-gamma, and lymphotoxin (LT). IFN-gamma is necessary for inhibition of CFU-GM by PHA-conditioned medium (CM), as shown by experiments in which removal of IFN-gamma from PHA-CM abrogated inhibition. However, experiments in which rIFN-gamma was a...
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 کاملPhenotypic 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 کاملCloning and Expression of Human Gamma-Interferon cDNA in E. coli
Prior to the production of human gamma interferon using recombinant DNA technology, it had been producedmainly upon mitogenic induction of lymphocytes in very low amounts, which evidently hamperedits characterization and its medical applications. The recombinant gamma interferons produced in largerquantities in prokaryotic systems retain their biological activities, and can be...
