This invention provides methods for inhibiting fusion of HIV-1 to CD4− cells which comprise contacting CD4− cells with a non-chemokine agent capable of binding to a chemokine receptor in an amount and under conditions such that fusion of HIV-1 to the CD4+ cells is inhibited. This invention also provides methods for inhibiting HIV-1 infection of CD4+ cells which comprise contacting CD4+ cells with a non-chemokine agent capable of binding to a chemokine receptor in an amount and under conditions such that fusion of HIV-1 to the CD4+ cells is inhibited, thereby inhibiting the HIV-1 infection. This invention provides non-chemokine agents capable of binding to the chemokine receptor and inhibiting fusion of HIV-1 to CD4+ cells. This invention also provides pharmaceutical compositions comprising an amount of the non-chemokine agent capable of binding to the chemokine receptor and inhibiting fusion of HIV-1 to CD4+ cells effective to prevent fusion of HIV-1 to CD4+ cells and a pharmaceutically acceptable carrier.
摘要:
This invention provides a composition which comprises a monoclonal antibody or a fragment of such antibody, wherein the monoclonal antibody or fragment of such antibody binds to the same epitope as antibody PA14 produced by a hybridoma cell line designated PA14 (ATCC Accession No. HB-12610) and a carrier. This invention also provides a method of treating a subject infected with HIV-1 which comprises administering to the subject an effective dose of the composition of the invention.

摘要:
This method provides a method for reducing HIV-1 viral load in an HIV-1-infected human subject which comprises administering to the subject at a predefined interval effective HIV-1 viral load-reducing doses of (a) a humanized antibody designated PRO 140, or of (b) an anti-CCR5 receptor monoclonal antibody. This invention also provides a method for inhibiting in a human subject the onset or progression of an HIV-1-associated disorder, the inhibition of which is effected by inhibiting fusion of HIV-1 to CCR5+CD4+ target cells in the subject. This invention also provides a method for treating a subject infected with HIV-1 comprising administering to the subject (a) a monoclonal antibody which (i) binds to a CCR5 receptor on the surface of the subject's CD4+ cells and (ii) inhibits fusion of HIV-1 to the subject's CCR5+CD4+ cells, and (b) a non-antibody CCR5 receptor antagonist, in amounts effective to treat the subject.
摘要:
Disclosed herein are isolated nucleic acids encoding a first polypeptide comprising a heavy chain of an anti-CCR5 antibody or a portion thereof containing three CDR regions, wherein the three CDR regions comprise consecutive amino acids, the sequences of such consecutive amino acids being identical to the sequences of CDR regions present in a heavy chain of a monoclonal antibody selected from the group: PA14, PA8, PA9, PA10, PA11, and PA12; and wherein the first polypeptide in combination with a second polypeptide comprising a light chain of an anti-CCR5 antibody binds to an epitope of CCR5 comprising amino acid residues in (1) an N-terminus of CCR5, (2) one of three extracellular loop regions of CCR5, or (3) a combination of (1) and (2).
摘要:
This invention relates generally to antibody-drug conjugates (ADCs). In particular, the invention relates to ADCs which comprise an antibody or antigen-binding fragment thereof which binds to prostate-specific membrane antigen (PSMA) and is conjugated to monomethylauristatin norephedrine or monomethylauristatin phenylalanine. The antibody-drug conjugate has a PC-3™ cell to C4-2 or LNCaP™ cell selectivity of at least 250. The invention also relates, in part, to compositions of and methods of using the ADCs. The methods provided include, for example, methods for treating a PSMA-mediated disease.
摘要:
This invention provides a composition which comprises an admixture of three compounds, wherein: (a) one compound is an antibody which binds to a CCR5 receptor; (b) one compound retards attachment of HIV-1 to a CD4+ cell by retarding binding of HIV-1 gp120 envelope glycoprotein to CD4 on the surface of the CD4+ cell; and (c) one compound retards gp41 from adopting a conformation capable of mediating fusion of HIV-1 to a CD4+ cell by binding noncovalently to an epitope on a gp41 fusion intermediate; wherein the relative mass ratio of any two of the compounds in the admixture ranges from about 100:1 to about 1:100, the composition being effective to inhibit HIV-1 infection of the CD4+ cell. This invention also provides a method of inhibiting HIV-1 infection of a CD4+ cell which comprises contacting the CD4+ cell with an amount of the composition of the subject invention effective to inhibit HIV-1 infection of the CD4+ cell so as to thereby inhibit HIV-1 infection of the CD4+ cell.
