摘要:
Reagents and assays for detecting HIV-1 groups M and O and optionally HIV-1 group N and SIVcpz are provided. The reagents are nucleic acid primers for the hybridization to, amplification and subsequent detection of HIV-1 groups M, N and O and SIVcpz in a biological sample. The primers are oligonucleotides that selectively hybridize to the highly conserved regions of the env and pol regions of HIV-1. Due to the high sensitivity of the assays, small concentrations of HIV in a biological sample can be detected, allowing diagnosis at an early stage of infection. The assays are qualitative or quantitative and are useful for viral load determinations of HIV-1 groups M, N or O in a patient undergoing treatment for HIV-1 infection. Viral load determinations can be used to monitor the progress of the treatment regimen, the development of drug resistance, and to predict disease progression.

摘要:
The invention provides antigenic peptides derived from immunodominant epitopes of the HTLV-I tax or rex proteins that are immunoreactive with antibodies associated with disease in HTLV-I infected subjects. More specifically, the invention provides antigenic peptides consisting essentially of the amino acid sequences defined in the sequence listing by SEQ ID NOs: 1, 2, 3, 4, 5, 6, 7 and 8 and antigenic fragments thereof. The invention provides a method of diagnosing HTLV-I associated myelopathy (HAM) or a predisposition thereto, comprising the steps of: (a) contacting an antibody containing sample from the subject with a detectable amount of a peptide of the invention or an antigenic fragment thereof; and (b) detecting the reaction of the peptide with an antibody in the sample, the reaction indicating HTLV-I associated myelopathy or a predisposition thereto. The invention also provides a method of diagnosing adult T-cell leukemia or a predisposition thereto in a subject, comprising the steps of: (a) contacting an antibody containing sample from the subject with a detectable amount of the peptide of SEQ ID NO: 1; and (b) detecting the reaction of the peptide with an antibody in the sample, the reaction indicating adult T-cell leukemia or predisposition thereto.

摘要:
Described herein are nucleic acid molecules which encode multiple highly conserved epitopes from HIV-1 proteins, and optionally also epitopes from CCR5; usually also included sequences that encode spacers between two or more of the epitopes. Some of the provided nucleic acid molecules further include sequences that encode targeting domains, useful for targeting the encoded protein into a pathway for enhancing epitope presentation in a vertebrate immune system. Also described are multivalent proteins encoded for by these nucleic acid molecules. The disclosure also encompasses immunogenic compositions that comprise one or more of the nucleic acid molecules, and/or one or more of the proteins encoded thereby, as well as methods of inducing an immune response against HIV-1 in a subject by administering to the subject an effective amount of a composition containing one or more of these molecules. Also provided are cultured host cells containing within them one or more of the described nucleic acid molecules.
