Bivalent proteins, including homobivalent and heterobivalent proteins, are made in the present invention. Genetic sequences coding for bivalent single-chain antigen-binding proteins are disclosed. Uses include all those appropriate for monoclonal and polyclonal antibodies and fragments thereof, including use as a bispecific antigen-binding molecule.

Abstract: The present invention is directed to compositions and methods for a genetic system of detecting protein--protein interactions in a mammalian host cell. Two fusion proteins are made in the host cell. The first fusion protein contains a DNA binding domain which is fused to a so-called bait protein. The second fusion protein consists of a transcriptional activation domain fused to a so-called test protein. The transcriptional activation domain is recruited to the promoter through the functional interaction between the bait protein and the test protein. Subsequently the transcriptional activation domain interacts with the basal transcription machinery to activate expression of one or more reporter genes which can be identified and characterized. The individual compositions are useful for analyzing protein--protein interactions between known proteins and to isolate, clone and characterize unknown proteins. The individual compositions can be used to express the fusion proteins either transiently or stably.

Abstract: A number of subunits of various rotaviral proteins have been shown to be useful in diagnosis, therapy, and prevention of rotaviral infection. Specifically, the subunits represented by positions 40-60 of VP6, 232-255 and 240-248 of VP4, and 247-259 and 275-295 of VP7 are thus useful. Furthermore, the VP4 subunits have therapeutic value in competing with the native viral protein in an essential step in infection.

Abstract: A method for neutralizing HIV-1 is disclosed. A preferred embodiment utilizes a novel human monoclonal antibody that binds to a conserved region of the gp41 transmembrane subunit of the virus. The antibody is produced by continuous cell lines developed using human B lymphocyte cells collected from a patient possessing high titers of anti-HIV antibodies. The conserved region bound by the neutralizing antibody is a peptide of approximately 12 amino acids in length. Similar regions on HIV-2 and SIV are also disclosed.

Abstract: Sialic acids have the ability to prevent hyposialylation of cells as comptive inhibitors of endogenous sialidase. It is now also possible to develop antibodies to mammalian sialidase that significantly reduce influx of neutrophils into inflammatory sites.

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 .beta.-chemokines RANTES, MIP-1.alpha., and MIP-1.beta.. It has also been found that individuals who are homozygous for a mutation of the CKR-5 receptor are resistent to HIV infection; in vitro infection requires a 1000-fold higher dose of HIV than normal cells. The mutation results in complete suppression of CKR-5 expression.

When gp140 oligomeric glycoproteins were purified by sucrose velocity gradient sedimentation, and then used to immunize mice, the resulting humoral immune response was skewed toward the production of antibodies that recognize conformation-dependent epitopes on the HIV-1 env protein. Assays for HIV-1 infections are described, as well as immonogens for vaccinating against HIV-1 infection.
