Abstract: The present invention relates, in general, to an immunogen and, in particular, to an immunogen for inducing antibodies that neutralizes a wide spectrum of HIV primary isolates and/or to an immunogen that induces a T cell immune response. The invention also relates to a method of inducing anti-HIV antibodies, and/or to a method of inducing a T cell immune response, using such an immunogen. The invention further relates to nucleic acid sequences encoding the present immunogens.

Abstract: Methods and compositions are provided which employ chimeric polypeptides having at least one heterologous epitope for a human immunodeficiency virus type 1 (HIV-1) neutralizing antibody. These chimeric polypeptides behave as molecular scaffolds which are capable of presenting the various heterologous HIV-1 epitopes. The invention demonstrates that a heterologous epitope recognized by the HIV-1 neutralizing antibody can be more fully exposed to neutralizing antibodies when presented within the backbone of the chimeric polypeptide than when the epitope is presented within the context of an HIV-1 backbone. Polynucleotides encoding these chimeric polypeptides are also provided. Immunogenic compositions are provided which comprise a chimeric polypeptide having at least one heterologous epitope that interacts with an HIV-1 neutralizing antibody. Immuno genie compositions comprising chimeric polynucleotides encoding the chimeric polypeptides of the invention are also provided.

Abstract: Provided herein are compositions and methods that allow for the study of HIV latency and reactivation. Further provided are compositions and methods for in vitro screening of agents for their ability to reactivate, suppress reactivation or inhibit transcription of HIV. Compositions for and methods for activating a cell are also provided herein. Further provided herein are methods of treating a subject using agents that reactivate latent HIV infection or agents that inhibit HIV transcription. Also provided herein are methods of activating a latent microbiological entity in a subject. Further provided herein are methods for enhancing an immune response in a subject and compositions used as a vaccination adjuvant. Methods of making disclosed cells and compositions are also provided herein.

Abstract: The nucleotide sequences of the genomes of eleven molecular clones for non-subtype B isolates of human immunodeficiency virus type 1 are disclosed. The invention relates to the nucleic acids and peptides encoded by and/or derived from these sequences and their use in diagnostic methods and as immunogens.

Abstract: The present disclosure relates to the determination of the complete genomic nucleic acid sequence of a new simian immunodeficiency virus (SIVcpzTAN1) isolated from a wild chimpanzee (Ch-06) from the Gombe National Park in Tanzania and to the nucleic acids derived therefrom. The disclosure also relates to the peptides encoded by and/or derived from the SIVcpzTAN1 nucleic acid sequence, to host cells containing the nucleic acids sequences and/or peptides, to diagnostic kits, immunogens and methods which employ the nucleic acids, peptides and/or host cells of the present disclosure, and to non-invasive methods for the detection of SIVcpz and related viruses from animal species in the wild.

Abstract: The nucleotide sequence and deduced amino acid sequences of the complete genome of a simian immunodeficiency virus isolate from a red-capped mangabey are disclosed. The invention relates to the nucleic acids and peptides encoded by and/or derived from these sequences and their use in diagnostic methods and as immunogens.

Abstract: An envelope protein of the etiologic agent of acquired immune deficiency syndrome (AIDS) and a method for its preparation are disclosed. Proviral DNA is transferred into a host cell after engineering into an expression vector which produces the envelope protein. A method of testing human blood for the presence of antibodies to the AIDS virus using the AIDS envelope protein is disclosed.
