  • 产品描述：

    The product CSB-E13423h is a sandwich ELISA kit developed to measure concentrations of human CD5L in serum, plasma, or tissue homogenates. This assay uses the sandwich enzyme immunoassay technique in combination with the enzyme-substrate chromogenic reaction to quantify the analyte in the sample. The color develops positively to the amount of CD5L in samples. The color intensity is measured at 450 nm via a microplate reader.

    CD5L is a secreted protein produced mostly by macrophages in lymphoid and inflamed tissues. It plays a critical role in immune homeostasis and inflammatory disease. It is involved in various diseases such as lipid metabolic disease, hepatocellular carcinoma, fungus-induced peritonitis, acute kidney injury, and myocardial infarction. CD5L localizes to CD36 to promote the transcription of genes involved in the regulation of mitochondrial biogenesis to maintain energy and metabolic homeostasis. CD5L also activates autophagy in macrophages while altering inflammatory phenotypes, specifically reducing TNF and IL-1 beta expression while elevating the immunosuppressive cytokine IL-10. Serum or plasma CD5L levels are increased in inflammatory conditions including liver cirrhosis, chronic hepatitis C, atopic dermatitis, and Kawasaki disease.

  • 功能：
    Secreted protein that acts as a key regulator of lipid synthesis: mainly expressed by macrophages in lymphoid and inflamed tissues and regulates mechanisms in inflammatory responses, such as infection or atherosclerosis. Able to inhibit lipid droplet size in adipocytes. Following incorporation into mature adipocytes via CD36-mediated endocytosis, associates with cytosolic FASN, inhibiting fatty acid synthase activity and leading to lipolysis, the degradation of triacylglycerols into glycerol and free fatty acids (FFA). CD5L-induced lipolysis occurs with progression of obesity: participates in obesity-associated inflammation following recruitment of inflammatory macrophages into adipose tissues, a cause of insulin resistance and obesity-related metabolic disease. Regulation of intracellular lipids mediated by CD5L has a direct effect on transcription regulation mediated by nuclear receptors ROR-gamma (RORC). Acts as a key regulator of metabolic switch in T-helper Th17 cells. Regulates the expression of pro-inflammatory genes in Th17 cells by altering the lipid content and limiting synthesis of cholesterol ligand of RORC, the master transcription factor of Th17-cell differentiation. CD5L is mainly present in non-pathogenic Th17 cells, where it decreases the content of polyunsaturated fatty acyls (PUFA), affecting two metabolic proteins MSMO1 and CYP51A1, which synthesize ligands of RORC, limiting RORC activity and expression of pro-inflammatory genes. Participates in obesity-associated autoimmunity via its association with IgM, interfering with the binding of IgM to Fcalpha/mu receptor and enhancing the development of long-lived plasma cells that produce high-affinity IgG autoantibodies. Also acts as an inhibitor of apoptosis in macrophages: promotes macrophage survival from the apoptotic effects of oxidized lipids in case of atherosclerosis. Involved in early response to microbial infection against various pathogens by acting as a pattern recognition receptor and by promoting autophagy.
