Publication number: 20160362478Abstract: Described herein are methods of generating a protein binding domain that specifically binds to gp120 in a specific conformational state, comprising contacting gp120 with a CD4-mimetic compound, thereby forming gp120 in the specific conformational state; and generating antibodies to gp120 in the specific conformation state. Relatedly, the disclosure also describes methods of neutralizing HIV-1, comprising contacting HIV-1 with an effective amount of a CD4-mimetic compound, thereby forming HIV-1 having gp120 in a specific conformational state; and contacting the HIV-1 in the specific conformational state with an antibody.Type: ApplicationFiled: February 10, 2015Publication date: December 15, 2016Inventors: Joseph SODROSKI, Navid MADANI, Amy M. PRINCIOTTO, Arne SCHON, Judith M. LaLONDE, Ernesto FREIRE, Amos B. SMITH, Richard T. WYATT, Jongwoo PARK, Joel R. COURTER, David M. JONES, Wayne A. HENDRICKSON, Xueling WU, Matthew LE-KHAC, Peter D.

Patent number: 7741024Abstract: An immunogenic proteoliposome containing a transmembrane protein or oligomeric complexes containing such proteins, including viral envelope glycoproteins, in a lipid membrane around an elliptoid or spherical shape. The shape preferably also contains an attractant such as streptavidin or avidin and the lipid membrane contains a moiety that binds to the attractant such as biotin. The immunogenic transmembrane protein is bound to a ligand which is anchored in the shape. Methods for making the immunogenic proteoliposomes are provided. uses of the proteoliposome are described, including their use as immunogens to elicit immune reaction, and their use in screening assays, including their use as antigens to screen antibody libraries, as well as for drug screening and the identification of ligands.Type: GrantFiled: July 24, 2007Date of Patent: June 22, 2010Assignee: Dana-Farber Cancer Institute, Inc.Inventors: Richard T Wyatt, Joseph G Sodroski, Tajib Mirzabekov, Christoph Grundner

Patent number: 7048929Abstract: A modified polypeptide corresponding to an envelope glycoprotein of a primate lentivirus is described. The polypeptide has been modified from the wild-type structure so that it has cysteine amino acid residues introduced to create disulfide bonds, a cavity is filled with hydrophobic amino acids, a Proresidue is introduced at a defined turn structure of the protein, or the hydrophobicity is increased across the interface between different domains, while retaining the overall 3-dimensional structure of a discontinuous conserved epitope of the wild-type protein. Preferably, the polypeptide has more than one of those characteristics. Preferably, the primate lentivirus is HIV, and the protein is HIV-1 gp120.Type: GrantFiled: November 10, 1998Date of Patent: May 23, 2006Assignees: Dana-Farber Cancer Institute, Inc., The Trustees of Columbia University in the City of New YorkInventors: Joseph G Sodroski, Richard T.

Patent number: 6908617Abstract: A modified polypeptide corresponding to an envelope glycoprotein of a primate lentivirus is described. The polypeptide has been modified from the wild-type structure so that it has at least two of the glycosylation sites proximal to the CD4 binding site or chemokine receptor site altered so that the alteration prevents glycosylation at that site or where glycosylation sites distal to these sites have been derivatized with a molecular adjuvant, while retaining the overall 3-dimensional structure of a discontinuous conserved epitope of the wild-type protein. Preferably, the polypeptide has both changes. Preferably, the primate lentivirus is HIV, and the protein is HIV-1 gp 120.Type: GrantFiled: November 10, 1998Date of Patent: June 21, 2005Assignees: Dana-Farber Cancer Institute, Inc., The Trustees of Columbia University in the City of New YorkInventors: Richard T. Wyatt, Joseph G. Sodroski, Peter D. Kwong, Wayne A. Hendrickson
