What is the role of IFN-alpha?
The main function of the IFN-alpha 1 is to alert the organism in case of viral infection by detection of abnormal double stranded DNA, but also to inhibit virus multiplication by action on the translation in infected cells.
What is IFN-alpha produced by?
IFN-alpha is produced in the leukocytes infected with virus, while IFN-beta is from fibroblasts infected with virus. IFN-gamma is induced by the stimulation of sensitized lymphocytes with antigen or non-sensitized lymphocytes with mitogens.
What is IFN gamma Elisa?
The Human Interferon-gamma (IFN-γ) ELISA Kit is designed for the quantitative detection and measurement of human IFN-γ in biological fluids such as serum, plasma, and cell culture supernatants. IFN-γ is primarily secreted by T and NK cells, but is also produced by dendritic cells and macrophages in smaller amounts.
Is IFN-alpha a cytokine?
Interferon (IFN) alpha, the first cytokine to be produced by recombinant DNA technology, has emerged as an important regulator of growth and differentiation, affecting cellular communication and signal transduction pathways as well as immunological control.
Is IFN alpha pro inflammatory?
Initially thought to have mainly immunomodulating and proinflammatory effects, recent data suggest that IFN alpha has several anti-inflammatory properties. These newly identified anti-inflammatory and immunosuppressive functions may help to explain some of the IFN mechanisms.
What are the side effects of interferon?
These side effects can include:
- swelling or other reactions at the injection site.
- flu-like symptoms such as headache, tiredness, and weakness.
- chills.
- fever.
- trouble sleeping.
- nausea.
- vomiting.
- diarrhea.
Is alpha interferon A protein?
Interferon is a small protein messenger called a pluripotent cytokine, produced by several cells of the host in response to various biological as well as synthetic stimuli. IFN-α has proved to be effective as an antiviral therapy and tumor-fighting drug in the past two decades.
Is IGRA the same as QuantiFERON?
QuantiFERON-TB Gold (QFT) is a simple blood test that aids in the detection of Mycobacterium tuberculosis, the bacteria which causes tuberculosis (TB). QFT is an interferon-gamma (IFN-γ) release assay, commonly known as an IGRA, and is a modern alternative to the tuberculin skin test (TST, PPD or Mantoux).
What is the role of interferon gamma?
IFN‐γ is primarily secreted by activated T cells and natural killer (NK) cells, and can promote macrophage activation, mediate antiviral and antibacterial immunity, enhance antigen presentation, orchestrate activation of the innate immune system, coordinate lymphocyte–endothelium interaction, regulate Th1/Th2 balance.
What do IFN alpha and beta do?
Innate cytokine responses are important mediators of early defense against infections. In the context of viral infections, interferons alpha and beta (IFN-alpha/beta) are induced to high levels, and help to mediate and regulate immune responses most effective against this class of agents.
What does IFN gamma do?
Are cytokines interleukins?
Interleukins. Interleukins are a group of cytokines that act as chemical signals between white blood cells.
What is the human IFN alpha Elisa?
The human IFN alpha ELISA is an enzyme-linked immunosorbent assay for the quantitative detection of human IFN alpha. The human IFN alpha ELISA is for research use only. Not for diagnostic or therapeutic procedures.
What is IFN-alpha signaling?
IFN-alpha signaling is well characterized (2, 5,11,12,13). IFN-alpha is a ligand for IFN alpha R, which includes two subunits IFN alpha R1 and IFN alpha R2. IFN-alpha ligand binding to the ubiquitously expressed IFN alpha R1 triggers a conformational change which allows for the heterodimerization of IFN alpha R1 and IFN alpha R2 (10).
How does the human IFNα solid-phase sandwich ELISA work?
The assay will exclusively recognize both natural and recombinant Hu IFNα. The Human IFNα solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody has been pre-coated in the wells of the supplied microplate.
How robust are IFN-alpha responses to viral infections?
IFN-alpha responses have been described as robust, especially in the context of viral infection responsiveness by all cells or tunable in a cell type specific manner. IFN-alpha signaling is well characterized (2, 5,11,12,13). IFN-alpha is a ligand for IFN alpha R, which includes two subunits IFN alpha R1 and IFN alpha R2.
