Immunoregulation by interleukin-12

Journal of Leukocyte Biology, 1996
Abstract Interleukin-12 (IL-12) is a heterodimeric cytokine produced primarily by antigen-presenting cells (monocytes, macrophages, dendritic cells, and B cells). Its production is stimulated by bacteria, bacterial products, and intracellular parasites and enhanced by priming with granulocyte-macrophage colony-stimulating factor (CM-CSF)

Interleukin-12

Journal of Leukocyte Biology, 1994
Abstract Interleukin-12 (IL-12) is a newly characterized cytokine that has a unique heterodimeric structure. It was initially cloned from B lymphoblastoid cell lines, but the majority of IL-12 is produced by macrophages/monocytes following appropriate stimulation. IL-12 can (1) enhance the cytolytic activity of a number of effector cells

Molecular characterization of interleukin 12

Archives of Biochemistry and Biophysics, 1992
Interleukin 12 (IL-12), formerly known as cytotoxic lymphocyte maturation factor and natural killer cell stimulatory factor, is a cytokine secreted by a human B lymphoblastoid (NC-37) cell line when induced in culture with phorbol ester and calcium ionophore. This factor has been purified to homogeneity and shown to synergize with low concentrations of

Interleukin-12

BioDrugs, 2003
Asthma is an inflammatory disease of the airways leading to significant morbidity and mortality. With advances in the understanding of the molecular and cellular mechanisms involved in the asthmatic response, researchers have identified specific mediators that may be targeted to control the inflammatory state of asthma. The Th2 hypothesis proposes that

The interleukin‐12 subunit p40 specifically inhibits effects of the interleukin‐12 heterodimer

European Journal of Immunology, 1993
AbstractThe recently discovered cytokine interleukin (IL)‐12 is a heterodimeric protein of two disulfide‐bonded subunits of 35 and 40 kDa. IL‐12 has multiple effects on T cells and natural killer (NK) cells. In particular it appears to be a major factor for the development of cellular immunity.

Interleukin 12 (IL12B) and Interleukin 12 Receptor (IL12RB1) Gene Polymorphisms in Rheumatoid Arthritis

Human Immunology, 2005
The aim of this study was to assess the possible association between the IL12B and the IL12RB1 gene polymorphisms and the systemic autoimmune disease rheumatoid arthritis (RA). Our study population consisted of 545 patients with RA and 393 healthy subjects. All the individuals were of white Spanish origin. Genotyping of the IL12B (IL12Bpro and IL12B 3'

Gene Therapy of Cancer with Interleukin-12

Current Pharmaceutical Design, 2003
IL-12 has demonstrated remarkable antitumor activity when used directly as a recombinant protein or when different viral or non-viral vectors transfer its genes. At enhancing tumor immunity, IL-12 acts as a bridge between innate and adaptive immune responses due to its ability to induce proliferation and activation of NK, NKT, and T cells. In addition,
