Single-cell analysis of macrophage chemotactic protein-1-regulated cytosolic Ca2+ increase in human adherent monocytes.
The increase in intracellular free Ca2+ ([Ca2+]i) associated with interaction of monocyte chemotactic protein-1 (MCP-1) and related chemokines beta with adherent human blood monocytes was investigated at the single-cell level. We used f-MLP as reference chemotactic agent. MCP-1 caused an increase in [Ca2+]i in individual adherent monocytes, with 95% of cells responding to the chemokine at 20 ng...
متن کاملInterferon-γ Stimulates Monocyte Chemotactic Protein-1 Expression by Monocytes
Monocyte chemotactic protein (MCP-1) is a specific monocyte chemoattractant and activating factor produced by both immune cells (mononuclear phagocytes and lymphocytes) and non-immune cells (parenchymal and stromal cells). In order to define the conditions under which human monocytes express MCP-1, monocytes were exposed to IFN-gamma, IL- lbeta, TNF-alpha, IL-4 or PHA under serum free condition...
متن کاملInterleukin-15 (IL-15) induces IL-8 and monocyte chemotactic protein 1 production in human monocytes.
Interleukin-15 (IL-15) is a recently characterized cytokine that shares many biological activities with IL-2 and interacts with the beta and gamma components of the IL-2 receptor. Unlike IL-2, which is secreted only by T cells, IL-15 is expressed preferentially by nonlymphoid tissues, epithelial, and fibroblast cell lines and by activated monocytes/macrophages. High concentrations of IL-15 have...
متن کاملHepcidin Induces M1 Macrophage Polarization in Monocytes or THP-1 Derived Macrophages
Background: Macrophage polarization plays a critical role in determining the inflammatory states. Hepcidin is a key negative regulator of iron homeostasis and functions. Although hepcidin has been shown to affect ferroportin expression in macrophages, whether it affects macrophage polarization is still largely unknown. Objective: To address whether hepcidin ind...
متن کاملadenylyl cyclase assays to measure macrophage chemotactic protein-1 receptor function
adenylyl cyclase is a membrane-bound enzyme that catalyzes the conversion of atp to camp. the inhibition of adenylyl cyclase was carried out by measuring the ability of the macrophage chemotactic protein-1 to inhibit the torskolin-induced enzyme activity. adenylyl cyclase activity in the presenc of macrophage chemotactic protein-1 was decreased compared to that in controls [2.11+/-0.15 (mean +/...
