  • 產(chǎn)品描述：

    The product CSB-E14200h is a sandwich ELISA kit developed to measure concentrations of human CCR2 in serum, plasma, cerebrospinal fluid (CSF), 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 CCR2 in samples. The color intensity is measured at 450 nm via a microplate reader.

    CCR2 is a functional chemotactic receptor mainly expressed on the surface of monocytes/macrophages and lymphocytes. It regulates many diseases by controlling the bone marrow monocytes' mobilization into the bloodstream and their migration to inflammatory sites. CCR2 plays an important role in the extravasation and transmigration of monocytes during inflammation. CCR2 is involved in liver pathology, including acute liver injury, chronic hepatitis, fibrosis/cirrhosis, and tumor progression, by mediating the recruitment of immune cells to inflammation and tumor sites. CCL2-CCR2 signaling is implicated in many disease pathogenesis, including cancer. Upregulation of CCR2 is associated with advanced cancer, metastasis, and relapse.

靶點(diǎn)詳情

  • 功能：
    Key functional receptor for CCL2 but can also bind CCL7 and CCL12. Its binding with CCL2 on monocytes and macrophages mediates chemotaxis and migration induction through the activation of the PI3K cascade, the small G protein Rac and lamellipodium protrusion (Probable). Also acts as a receptor for the beta-defensin DEFB106A/DEFB106B. Regulates the expression of T-cell inflammatory cytokines and T-cell differentiation, promoting the differentiation of T-cells into T-helper 17 cells (Th17) during inflammation. Facilitates the export of mature thymocytes by enhancing directional movement of thymocytes to sphingosine-1-phosphate stimulation and up-regulation of S1P1R expression; signals through the JAK-STAT pathway to regulate FOXO1 activity leading to an increased expression of S1P1R. Plays an important role in mediating peripheral nerve injury-induced neuropathic pain. Increases NMDA-mediated synaptic transmission in both dopamine D1 and D2 receptor-containing neurons, which may be caused by MAPK/ERK-dependent phosphorylation of GRIN2B/NMDAR2B. Mediates the recruitment of macrophages and monocytes to the injury site following brain injury.; (Microbial infection) Alternative coreceptor with CD4 for HIV-1 infection.
