一般說明
Millipore′s Ready-to-Assay GPCR frozen cells are designed for simple, rapid calcium assays with no requirement for intensive cell culturing. Millipore has optimized the freezing conditions to provide cells with high viability and functionality post-thaw. The user simply thaws the cells and resuspends them in media, dispenses cell suspension into assay plates and, following over night recovery, assays for calcium response.
CCR5 is the receptor for CC chemokines MIP-1α, MIP-1β, and RANTES (Raport et al., 1996), and is preferentially expressed on Th1 lymphocytes (Loetscher et al., 1998). CCR5 is a coreceptor for macrophage-tropic HIV, and its ligands potently inhibit HIV replication in human leukocytes (Cocchi et al., 1995). In addition, HIV-infected patients with the nonfunctional CCR5Δ32 allele exhibit delayed onset of AIDS symptoms (Samson et al., 1996), and pharmacological antagonism of CCR5 inhibits HIV-1 infection (Strizki et al., 2001). Preclinical testing of small molecule antagonists of CCR5 has been hampered by low affinity of the compounds to rodent and dog CCR5, but two such compounds, maraviroc and AD101, have been shown to have potent antagonist activity at rhesus macaque CCR5, which differs from human CCR5 by 8 amino acids (Napier et al., 2005; Billick et al., 2004). One antagonist of human CCR5, SCH-C, does not block HIV entry through rhesus macaque CCR5, and one amino acid difference is responsible for the functional difference (Billick et al., 2004). Millipore′s cloned rhesus macaque CCR5-expressing cell line is made in the Chem-1 host, which supports high levels of recombinant CCR5 expression on the cell surface and contains high levels of the promiscuous G protein Gα15 to couple the receptor to the calcium signaling pathway. Thus, the cell line is an ideal tool for screening for agonists, antagonists and modulators at CCR5.
