摘要:
This invention is in the field of lymphadenopathy virus, which has been designated Human Immunodeficiency Virus Type 1 (HIV-1) to detect the presence of DNA, RNA or antibodies of the lymphadenopathy retrovirus associated with the acquired immune deficiency syndrome or of the lymphadenopathy syndrome by the use of DNA fragments or the peptides encoded by said DNA fragments. The invention further relates tot he DNA fragments, vectors comprising them and the proteins expressed.
摘要:
A new human B lymphotropic virus, also designated human herpesvirus-6, has been isolated. DNA, molecular clones, antigenic viral proteins and antibodies having specificity to the new virus have been prepared. Various utilities of the new virus and products derived therefrom have been described.

The present invention relates to &bgr;-hCG, particularly &bgr;-hCG proteins having a sequence of amino acids 41-54, 45-54, 47-53, 45-57 and 45-58 and analogs and derivatives thereof. The invention further relates to methods of treatment and prevention of HIV infection by administration of a therapeutic compound of the invention. Such therapeutic compounds include hCG, &bgr;-hCG and &bgr;-hCG peptides, analogs and derivatives of hCG, &bgr;-hCG and &bgr;-hCG peptides, and nucleic acids encoding hCG, &bgr;-hCG and &bgr;-hCG peptides. In a preferred embodiment, &bgr;-hCG peptides, particularly &bgr;-hCG peptides of amino acids 47-53, 45-57 or 45-58 are administered to a subject for treatment or prevention of HIV infection in that subject. The invention also provides methods for screening hCG preparations for activity in treating or preventing HIV infection. Pharmaceutical compositions and methods of administration of Therapeutics are also provided.
摘要:
The present invention relates to therapeutic compositions of macrophage derived chemokine (MDC) and methods for treating and preventing infection by a lentivirus, particularly an immunodeficiency virus, particularly HIV, using MDC proteins, nucleic acids and/or derivatives or analogues thereof. The present invention further relates to methods for detection and prognosis of lenivirus infection, particularly HIV infection using MDC as a prognostic indicator. The present invention further provides MDC proteins, nucleic acids encoding such proteins, that have amino-terminal sequences that differ from other MDC isolates. Recombinant host cells and methods of production are also provided.

摘要:
A method for inhibiting replication of reverse transcriptase dependent virus in plant or animal cells, comprising the step of administering to said cells a compound that depletes the intracellular pool of deoxyribonucleoside phosphate in an amount effective to inhibit replication of said virus. Hydroxyurea is one such suitable compound. Also disclosed is a method for producing incomplete reverse-transcriptase dependent viral DNA, by administering a deoxyribonucleoside phosphate-depleting drug to cells infected with such a virus.
摘要:
Novel hybridoma cell lines and monoclonal antibodies are provided which can differentiate between HIV-1, HIV-2 and SIV retrovirus isolates. A synthetic peptide which is useful as a universal diagnostic reagent for detecting retroviral infection is also described.
摘要:
Retroviruses associated with Acquired Immune Deficiency Syndrome (AIDS), including Lymphadenopathy Associated Virus (LAV), are isolated from the sera of patients afflicted with Lymphadenopathy Syndrome (LAS) or AIDS. LAV is a Human Immunodeficiency Virus (HIV). Viral extract, structural proteins and other fractions of the retrovirus immunologically recognize the sera of such patients. Immunological reaction is used to detect antibodies that specifically bind to antigenic sites of the retrovirus in samples of body fluids from patients with AIDS or risk of AIDS. A kit for in vitro assay of LAS or AIDS is provided.
摘要:
The invention relates to nucleotides encoding therapeutic polypeptides and fragments thereof isolated from beta-human chorionic gonadotropin (β-hCG) found in human early pregnancy urine, now synthetically produced and designated Maternin. The therapeutic polypeptides and their functional equivalents are useful in treating and/or preventing various medical conditions. Examples of therapeutic effects of the therapeutic polypeptides include anti-HIV, anti-cancer, anti-wasting, prohematopoietic (e.g., anemias, radiation-mediated bone marrow damage, and trauma-mediated blood loss), and anti-angiogenic effects. The invention also provides pharmaceutical compositions comprising the therapeutic polypeptides, as well as methods for using the therapeutic polypeptides, functional equivalents and/or pharmaceutical compositions in the treatment and/or prevention of such medical conditions.
