Background

IFN-gamma (Interferon-gamma) is the prototype proinflammatory cytokine and is produced by a variety of immune cells under inflammatory conditions, notably by T cells and NK cells. FNγ is secreted by T helper cells , cytotoxic T cells and NK cells only. IFNγ is the only Type II interferon and it is serologically distinct from Type I interferons; it is acid-labile, while the type I variants are acid-stable. 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.

In addition, IFN-gamma functions as an anti-inflammatory mediator by promoting the development of regulatory T cells and inhibiting Th17 cell differentiation. IFN-gamma dimers signal through a receptor complex of two IFN-gamma R1 and two IFN-gamma R2 subunits.

背景

脂联素，也称为Acrp30，是脂肪细胞衍生的蛋白质，对代谢和炎症具有广泛的旁分泌和内分泌作用。它促进脂肪细胞分化，脂肪酸分解代谢和胰岛素敏感性，并且与肥胖症，2型糖尿病和动脉粥样硬化形成负相关。脂联素缔合成70 kDa非共价连接的三聚体，该三聚体被二硫键连接成中等分子量的六聚体。
