High-throughput screening (HTS) has been postulated in several quarters to be a contributory factor to the decline in productivity in the pharmaceutical industry. Moreover, it has been blamed for stifling the creativity that drug discovery demands. In this article, we aim to dispel these myths and present the case for the use of HTS as part of a proven(More)
TRPA1 channels have been found to play an important role in mammalian pain sensation, especially when the pain is caused by chemicals on site of inflammation. A large number of structurally diverse chemicals are found to activate TRPA1 channels, implicating a potential chemosensor in neuronal nociception. Identification of the channel activation by cysteine(More)
The immunodeficiency in CBA/N mice is reflected by abnormal development of a subset of B lymphocytes. However, it is not clear how xid, the mutant gene in CBA/N mice, affects the development of this subset. Specifically, it is not known if the xid gene influences the development of the B cell subset directly or indirectly by providing the improper(More)
Link proteins from bovine nasal cartilage have been purified by preparative polyacrylamide gel electrophoresis in sodium dodecyl sulfate (Baker, J.R., and Caterson, B. (1979) J. Biol. Chem. 254, 2387-2393) and used to raise antisera in rabbits. A sensitive radioimmunoassay procedure utilizing binding of 125I-labeled antigen . antibody complexes to Protein A(More)
ABSTRACT Transient receptor potential (TRP) channels have been found to play important roles in cellular physiology and hold promise as therapeutic targets. These channels activate in response to a variety of chemical or physical stimuli and conduct non-selective cation currents (NSCC). Due to their unique activation properties, application of automated(More)
The gene for human interleukin-1 beta was cloned from SK-hep-1 hepatoma cellular RNA and expressed at high levels in Escherichia coli both as the naturally processed form (rIL-1 beta) and as a variant with an additional sequence of three amino acids on the N-terminus (rIL-1 beta +). Expressed protein was purified to homogeneity by a sequence of steps, which(More)
The effects of a panel of hormones and pharmacological agents on the activation of T cells by a combination of interleukin-1 and phytohemagglutinin (IL-1/PHA) was studied. Pharmacological effects on various stages of IL-1/PHA-induced interleukin-2 (IL-2) production by the cloned murine thymoma cell line LBRM-33-1A5.7 were dissected using a multi-step assay(More)
A protein with an apparent m.w. of 68,000 has been observed in immunoprecipitations of NP-40 solubilized BW5147 thymoma cells by using monoclonal or polyclonal allospecific H-2Kk antisera. By contrast, H-2Dk alloantisera precipitated a 45,000 m.w. protein from the same membrane preparations. The 68,000 m.w. protein is expressed on the plasma membrane as(More)
Specific binding of iodinated-interleukin-1 alpha or beta to YT cells could be inhibited by the lectins wheat germ agglutinin (WGA) and concanavalin A (Con A). WGA and Con A inhibition of IL-1 binding was abrogated by previous exposure of these plant proteins to the lectin-specific sugars N-acetylglucosamine (GlcNAc) and methyl glucoside (MG), respectively.(More)
