Scientific Data Images for Cotton Rat IFN‑ gamma Antibody

IFN‑ gamma Inhibition of EMC-induced Cytopathy and Neutralization by Cotton Rat IFN‑ gamma Antibody.

Recombinant Cotton Rat IFN-gamma (Catalog # 565-RG) reduces the encephalomyocarditis (EMC)-induced cytopathy in the LCRT cotton rat fibrosarcoma cell line in a dose-dependent manner (orange line), as measured by crystal violet staining. Inhibition of EMC activity elicited by Recombinant Cotton Rat IFN-gamma (20 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Cotton Rat IFN-gamma Antigen Affinity-purified Polyclonal Antibody (Catalog # AF565). The ND₅₀ is typically 0.3-1.2 µg/mL.

Background: IFN-gamma

Interferon-gamma (IFN-gamma ), also known as type II or immune interferon, exerts a wide range of immunoregulatory activities and is considered to be the prototype proinflammatory cytokine (1, 2). Mature cotton rat IFN-gamma exists as a noncovalently linked homodimer of 20‑25 kDa variably glycosylated subunits (3). It shares 43%‑50% amino acid sequence identity with bovine, canine, equine, feline, human, mouse, rat, rhesus, and porcine IFN-gamma. IFN-gamma dimers bind to IFN-gamma RI (alpha subunits) which then interact with IFN-gamma RII (beta subunits) to form the functional receptor complex of two alpha and two beta subunits. Inclusion of IFN-gamma RII increases the binding affinity for ligand and the efficiency of signal transduction (4, 5). IFN-gamma is produced by a variety of immune cells under inflammatory conditions, notably by T cells and NK cells (6). It plays a key role in host defense by promoting the development and activation of Th1 cells, chemoattraction and activation of monocytes and macrophages, upregulation of antigen presentation molecules, and immunoglobulin class switching in B cells. It also exhibits antiviral, antiproliferative, and apoptotic effects (6, 7). In addition, IFN-gamma functions as an anti-inflammatory mediator by promoting the development of regulatory T cells and inhibiting Th17 cell differentiation (8, 9). The pleiotropic effects of IFN-gamma contribute to the development of multiple aspects of atherosclerosis (7).
