Background

C-reactive protein (CRP) is an annular (ring-shaped), pentameric protein found in blood plasma, whose levels rise in response to inflammation. It is an acute-phase protein of hepatic origin that increases following interleukin-6 secretion by macrophages and T cells. Its physiological role is to bind to lysophosphatidylcholine expressed on the surface of dead or dying cells in order to activate the complement system via the C1Q complex.

CRP is synthesized by the liver in response to factors released by macrophages and fat cells. It is a member of the pentraxin family of proteins. It is not related to C-peptide or protein C. C-reactive protein was the first pattern recognition receptor (PRR) to be identified. CRP binds to the phosphocholine expressed on the surface of dead or dying cells and some bacteria. This activates the complement system, promoting phagocytosis by macrophages, which clears necrotic and apoptotic cells and bacteria.

This acute phase response occurs as a result of a rise in the concentration of IL-6, which is produced by macrophages as well as adipocytes in response to a wide range of acute and chronic inflammatory conditions such as bacterial, viral, or fungal infections; rheumatic and other inflammatory diseases; malignancy; and tissue injury and necrosis. These conditions cause release of interleukin-6 and other cytokines that trigger the synthesis of CRP and fibrinogen by the liver.

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。
