Scientific Data Images for Feline IFN-gamma Antibody

IFN-? antibody in Feline PBMCs by Immunocytochemistry (ICC).

IFN‑ gamma in Feline PBMCs.

IFN-gamma was detected in immersion fixed feline peripheral blood mononuclear cells (PBMCs) using Mouse Anti-Feline IFN-gamma Monoclonal Antibody (Catalog # MAB764) at 25 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

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 feline IFN-gamma exists as a noncovalently linked homodimer of 20  25 kDa variably glycosylated subunits (3, 4). It shares 88% amino acid sequence identity with canine IFN-gamma, 72%‑78% with bovine, equine, and porcine IFN‑ gamma, and 40%‑62% with cotton rat, human, mouse, rat, and rhesus 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 (5, 6). IFN-gamma is produced by a variety of immune cells under inflammatory conditions, notably by T cells and NK cells (7). 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 (7, 8). In addition, IFN-gamma functions as an anti-inflammatory mediator by promoting the development of regulatory T cells and inhibiting Th17 cell differentiation (9, 10). The pleiotropic effects of IFN-gamma contribute to the development of multiple aspects of atherosclerosis (8).
