Autoantibody-induced internalization of CNS AQP4 water channel and EAAT2 glutamate transporter requires astrocytic Fc receptor. When animals or cells are treated with Clodrosome®, phagocytic cells recognize the liposomes as invading foreign particles and proceed to remove the liposomes from the local tissue or serum via phagocytosis. Mouse macrophages are extensively studied in tissues and tumor. However, phagocytes do respond to the ingestion of control liposomes by cytokine secretion, temporary suspension of phagocytic activity and other responses described in the literature. 2014 Sep 1;31(9):2453-62, Mayo L, Cunha AP, Madi A, Beynon V, Yang Z, Alvarez JI, Prat A, Sobel RA, Kobzik L, Lassmann H, Quintana FJ.

The content of the website can only be used by researchers, educators and students for Both are prepared and packaged under sterile conditions. Macrophage depletion was performed with a protocol modified from Elmore et al. If the suspension is frozen, clodronate can be released from the liposomes thus limiting its effectiveness in depleting macrophages. Contact FedEx or DHL in advance and make sure that the paperwork for customs is done on time. Dose control animals first to become familiar with large volume injections. Vigorous or erratic shaking will not damage the liposomes but may induce foaming and bubble formation making it more difficult to accurately measure the desired dosage. 8. We strongly encourage the clients in Japan, Korea, Taiwan and China to order via a distributor. Clodrosome® is a multilamellar liposome suspension in which clodronate is encapsulated in the aqueous compartments of the liposomes. When Clodrosome® induces macrophage apoptosis, the fluorescent lipid incorporated into the Clodrosome® that is disrupted and metabolized in the phagolysosome will be dispersed among the residual apoptotic bodies which are subsequently phagocytosed by other macrophages. Any commercial use of the content of the website is legally prohibited The depletion of macrophages has been accomplished by means of a CSF-1R, Flt3, and c-kit inhibitor, PLX3397, delivered to mice through the chow … Background Tumour-associated macrophages (TAMs) are often implicated in cancer progression but can also exert anti-tumour activities. 10A, B) and mast cell depletion was confirmed via histological staining (Supporting Fig. We tested the c-Kit inhibitor, imatinib, and PLX3397, a selective c-Fms and c-Kit inhibitor, to evaluate their efficacy against MPNST cells in vitroand in vivo.
