Abstract: Methods of identifying a compound that selectively modulates at least one TLR-mediated cellular activity are disclosed. Generally, the methods include identifying a compound as a compound that selectively modulates at least one TLR-mediated cellular activity if the compound modulates one TLR-mediated cellular activity to a different extent than it modulates a second TLR-mediated cellular activity. Compounds so identified and pharmaceutical compositions including such compounds are also disclosed. Methods of selectively modulating immune cells and methods of treating certain conditions are also provided. Such methods include administering to cells or a subject a compound that selectively modulates a TLR-mediated cellular activity.

Abstract: The present invention provides gene expression systems useful for detecting agonists of Toll-like receptors. The gene expression systems include a nucleic acid sequence encoding a Toll-like receptor and a second nucleic acid sequence that encodes a reporter operably linked to an expression control sequence. The recombinant cell lines include a gene expression system according to the present invention.

Abstract: Methods of identifying compounds that selectively modulate cellular activities mediated by a common TLR are provided. Generally, the methods include providing an assay to detect modulation of a first cellular activity mediated by a TLR; providing an assay to detect modulation of a second cellular activity mediated by the TLR; performing each assay using a test compound; and identifying the test compound as a compound that selectively modulates at least one cellular activity of a plurality of activities mediated by a common TLR if the test compound modulates the first cellular activity to a different extent than it modulates the second TLR-mediated cellular activity. Compounds identified by such methods, pharmaceutical compositions including such compounds, and methods of treating a condition by administering such pharmaceutical compositions to a subject are also provided.

Abstract: Aryl substituted imidazoquinoline compounds, pharmaceutical compositions containing the compounds, intermediates, and methods of use of these compounds as immunomodulators, for inducing or inhibiting cytokine biosynthesis in animals and in the treatment of diseases including viral, and neoplastic, are disclosed.

Abstract: The present invention provides assays useful for detecting agonists of Toll-like receptors. The assays include, generally, providing a cell culture transfected with a nucleic acid sequence that encodes a reporter operably linked to a TLR-inducible expression control sequence; contacting the cell culture with a test compound; and identifying the compound as a TLR agonist if TLR-inducible expression of the reporter can be detected.

Abstract: The present invention is based of the discovery of two modified forms of human platelet factor-4, herein named MPF-4 and CPF-4, which were isolated from serum free culture medium of lipopolysaccharide-stimulated peripheral blood leukocytes. Amino acid sequence determination revealed that MPF-4 shares homology with platelet factor-4 beginning at N-terminal residue 17. CPF-4 consists of MPF-4 disulfide bonded to the 16 N-terminal residues of platelet factor-4. Both MPF-4 and CPF-4 are potent inhibitors of endothelial cell proliferation, approximately 10-100 fold more potent than native or recombinant platelet factor-4, making them useful in the treatment of angiogenic diseases.
