  • Publication number: 20130287815
    Abstract: The present invention is directed to an in vitro method for promoting differentiation and proliferation of human T helper lymphocytes that express IL17 (Th-IL17+ cells). The instant method may be used to generate a population of human T helper lymphocytes that express IL17 (Th-IL17+ cells) in vitro. Methods for screening to identify agents capable of modulating Th-IL17+ cell differentiation are also encompassed by the present invention. Isolated, pure populations of homogeneous Th-IL17+ cells that do not express cellular markers characteristic of Th1, Th2, or Treg cells are also encompassed herein.

  • Patent number: 7129055
    Abstract: Entry of HIV-1 into target cells requires cell surface CD4 as well as additional host cell cofactors. A cofactor required for infection with virus adapted for growth in transformed T cell lines was recently identified and named fusin. Fusin, however, does not promote entry of macrophage-tropic viruses that are believed to be the key pathogenic strains in vivo. It has now been determined that the principal cofactor for entry mediated by the envelope glycoproteins of primary macrophage-tropic strains of HIV-1 is CC-CKR5, a receptor for the ?-chemokines RANTES, MIP-1?, and MIP-1?.

  • Patent number: 6696244
    Abstract: The present invention provides two new HIV/SIV translocation promoting agents, Bonzo and BOB. The present invention also provides the amino acid and DNA sequences of human, African green monkey, and pigtail macaque of the receptor protein Bonzo. Mammalian cells transfected with Bonzo and/or BOB and human CD4 as well as antibodies to the receptor Bonzo are also included. Furthermore, a method of identifying other such translocation promoting agents is also disclosed. Diagnostic and therapeutic uses of the translocation promoting agents of the present invention are also provided. Furthermore, the present invention provides methods of identifying agents that can modulate the expression and/or function of Bonzo/STRL33. Such agents can be used to either treat inflamation, or alternatively, to enhance the immune response.

  • Patent number: 6570000
    Abstract: A single-stranded nucleic acid molecule which encodes an amino acid sequence comprising at least a portion of a T4 glycoprotein is provided. Additionally, amino acid sequences which comprise at least a portion of a T4 glycoprotein and are useful as a prophylaxis for treating a subject with acquired immune deficiency syndrome are provided. These amino acid sequences, which are capable of specifically forming a complex with a human immunodeficiency virus envelope glycoprotein and which are soluble in an aqueous solution may be administered to a subject infected with a human immunodeficiency virus so as to block the human immunodeficiency virus from binding to T4+ cells. Monoclonal antibodies directed to the water-soluble amino acid sequences of the present invention may be used as vaccines for immunizing a subject against acquired immune deficiency syndrome.
