Regulation of GM-CSF gene transcription by core-binding factor.
GM-CSF gene activation in T cells is known to involve the transcription factors nuclear factor-kappa B, AP-1, NFAT, and Sp1. Here we demonstrate that the human GM-CSF promoter and enhancer also encompass binding sites for core-binding factor (CBF). Significantly, the CBF sites are in each case contained within the minimum essential core regions required for inducible activation of transcription...
متن کاملPCR-mediated Expression of the Human GM-CSF Gene in Escherichia coli
Four exons of the human genomic GM-CSF gene were assembled together using gene splicing by overlap extension (SOE) method. The resulting nucleotide sequence was cloned in the pET23a(+) expression vector under the control of strong bacteriophage T7 transcription and translation signals. The construct obtained was Transferred into the E. coli strain, BL21(DE3) pLysS and IPTG was used for inducti...
متن کاملRegulation of MHC class II gene expression in macrophages by hematopoietic colony-stimulating factors (CSF). Induction by granulocyte/macrophage CSF and inhibition by CSF-1
CSF-1 and granulocyte/monocyte CSF (GM-CSF) were shown to modulate the levels of Ia gene and protein expression in bone marrow-derived macrophages (BMM). Recombinant GM-CSF induced high levels of Ia expression, similar to the levels induced by INF-gamma, while IL-3 had no effect. In contrast, recombinant CSF-1 not only suppressed the basal levels of Ia gene and protein expression in BMM, but al...
متن کاملGM-CSF regulation in eosinophils.
Allergic asthma is characterized by a temporally and quantitatively inappropriate immunologic response. One of the hallmarks of this response is the accumulation of eosinophils in the airway and lung parenchyma, which results in broncho-constriction, lung damage and, ultimately, fibrosis. Granulocyte-macrophage colony-stimulating factor (GM-CSF) plays a pivotal role in this process by modulatin...
متن کاملThe influence of protein malnutrition on the production of GM-CSF and M-CSF by macrophages
It is well established that protein malnutrition (PM) impairs immune defenses and increases susceptibility to infection. Macrophages are cells that play a central role in innate immunity, constituting one of the first barriers against infections. Macrophages produce several soluble factors, including cytokines and growth factors, important to the immune response. Among those growth factors, gra...
