Cloning and high level expression of bovine interferon gamma gene in eukaryotic cells (COS-7)
Interferon gamma (IFN-γ) is one of the key cytokines in defining T helper 1 lymphocyte immuneresponses. In this study, the bovine IFN-γ gene was cloned from spleen tissue RNA using the reversetranscription-polymerase chain reaction (RT-PCR). IFN-γ cDNA was sub-cloned and expressed inmammalian expression plasmid (pcDNA3.1(+)) under the control of the human cytomegalovirus (CMV)promoter. The pred...
متن کاملG-protein Coupled Receptor Dimerization
A growing body of evidence suggests that GPCRs exist and function as dimers or higher oligomers. The evidence for GPCR dimerization comes from biochemical, biophysical and functional studies. In addition, researchers have shown the occurrence of heterodimerization between different members of the GPCR family. Two receptors can interact with each other to make a dimer through their extracellular...
متن کاملGamma-interferon induces expression of the HLA-D antigens on normal and leukemic human myeloid cells.
Gamma-Interferon (IFN-gamma) is a lymphokine produced by T lymphocytes. We find that recombinant human IFN-gamma induces expression of HLA-D antigens on human promyelocytic leukemia cells (HL-60) and enhances expression of HLA-D antigens on normal human monocytes and macrophages. Induction of both HLA-D antigen expression and HLA-D mRNA accumulation occurs within 1 day of exposure of HL-60 to I...
متن کاملHigh levels of interferon gamma in the plasma of children with complete interferon gamma receptor deficiency.
We have found that children with complete interferon gamma (IFNgamma) receptor deficiency, unlike patients with other genetic defects predisposing them to mycobacterial diseases, have very high levels of IFNgamma in their plasma. This unexpected observation provides a simple and accurate diagnostic method for complete IFNgamma receptor deficiency in children with clinical disease caused by baci...
متن کاملImmune interferon induces the receptor for monomeric IgG1 on human monocytic and myeloid cells
We report here that FcR for human monomeric IgG1 can be induced on cells of myeloid origin cultured in the presence of IFN gamma for 8 h. Supernatant fluids from cultures of lymphocytes infected with a variety of viruses or cocultured with cell lines have the same FcR enhancing effect as IFN gamma. We identify the factor in the supernatant fluid responsible for the induction as immune interfero...
