Background | The Quantikine Human IFN-gamma Immunoassay is a 4.5 hour solid phase ELISA designed to measure human IFN-gamma levels in cell culture supernates, serum, and plasma. It contains HEK293-expressed recombinant human IFN-gamma and antibodies raised against the recombinant factor. Results obtained for naturally occurring human IFN-gamma samples showed linear curves that were parallel... to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural human IFN-gamma . Show More |

The biologically active form of IFN-gamma is a non-covalently linked homodimer (24), which binds with high affinity to IFN-gamma R1/CD119 and subsequently recruits IFN-gamma R2 to form the functional heterotetrameric receptor complex. Formation of this complex leads to phosphorylation and activation of the Janus kinases, Jak1 and Jak2, which in turn phosphorylate and activate STAT1. STAT1 homodimerizes and translocates to the nucleus where it binds to IFN-gamma -activated sequence (GAS) elements in the promoters of target genes to regulate their transcription. Many of the IFN-gamma /STAT1 target genes are transcription factors that then drive the expression of secondary response genes. Additionally, IFN-gamma signaling has been shown to activate MAPK, PI 3-K/Akt, and the NF-kappa B signaling pathways, leading to the expression of multiple other genes. IFN-gamma signaling plays a key role in host defense by promoting macrophage activation, upregulating the expression of antigen processing and presentation molecules, driving the development and activation of Th1 cells, enhancing natural killer cell activity, regulating B cell functions, and inducing the production of chemokines that promote effector cell trafficking to sites of inflammation.
Due to its immunoregulatory activities, IFN-gamma has been used as a therapeutic agent for treating a range of bacterial, fungal, helminth, protozoan, and viral infections, immunodeficiency syndromes, multi-drug resistant tuberculosis (MDR-TB), and sepsis (1, 25-34). Additionally, it has been used as an anti-tumor agent to improve patient survival in a number of different types of cancer due to its pro-apoptotic and anti-angiogenic effects (3, 35). In contrast, IFN-gamma has been suggested to be involved in the progression of cardiac diseases as elevated levels of this cytokine have been detected in the serum of patients with chronic heart failure, as well as in atherosclerotic lesions and in myocardial tissues of patients with Chagas' cardiomyopathy (1, 36, 37). Similarly, high levels of IFN-gamma have been found in the serum and/or cerebrospinal fluid of patients with neurodegenerative diseases such as Amyotrophic lateral sclerosis and Parkinson's disease (38, 39), suggesting that IFN-gamma may also be involved in neurodegenerative disease progression and serve as a clinical biomarker. Additionally, there is recent evidence suggesting that IFN-gamma may also have context-dependent proliferative and pro-tumorigenic effects (3).
