Patent number: 5767072Abstract: Disclosed are methods and compositions for the treatment of HIV infections through the specific elimination of cells which express HIV env determinants such as gp120. The compositions of the invention include toxin conjugates composed of a CD4 derived gp120 binding ligand conjugated to a toxin A chain moiety such as ricin A chain or deglycosylated ricin A chain. Where a therapeutic composition is desired, the conjugates are formed by means of a cross linker which includes a disulfide bond. Disulfide linkages are not crucial where non-therapeutic uses, such as antibody generation, is intended. In preferred aspects of the invention, conjugates incorporating shorter CD4 peptides, such as those incorporating amino acids 41-57 or 41-84 of CD4, are disclosed.Type: GrantFiled: December 21, 1993Date of Patent: June 16, 1998Assignee: Board of Regents, The University of Texas SystemInventors: Ellen S.
