摘要:
Monoclonal antibodies, and hybridoma cell lines for their production, that bind with a high degree of specificity proteins associated with HTLV-III virus are presently disclosed. In particular, transmembrane envelope glycoprotein gp41 (41,000 dalton molecular size), major core antigen p24 (24,000 dalton molecular size), and p17 protein (17,000 dalton molecular size) are disclosed. The proteins to which the present monoclonal antibodies respond are essentially antigenically distinct from HTLV-I and HTLV-II. SVM-16 is an IgM monoclonal antibody, SVM-23 is an IgG.sub.2 monoclonal antibody, and SVM-26 is an IgG.sub.1 monoclonal antibody, all of which bind to p24. SVM-25 is an IgG.sub.1 monoclonal antibody binding gp41, and SVM-33 is an IgG.sub.1 monoclonal antibody binding p17. All the monoclonal antibodies of the present invention are produced in hybridoma cells prepared by fusing myeloma cells with spleen cells from mammals, such as mice, immunized with lysates of purified virus.
摘要:
The identification, separation, purification, and propagation of the HIV-1 virus is provided. Moreover, the preparation of antigens from HIV-1 is further provided. The identification of HIV-1 involves the purification of a virus sample from lymphocytes and contacting the sample with antibodies, which bind to HIV-1 viruses, is provided. The propagation of HIV-1 virus involves infecting uninfected T lymphocytes with the virus. Moreover, the preparation of antigens from HIV-1 involves the separation of protein components of a purified HIV-1 virus under denaturing conditions.
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:
This invention relates to the detection of antibodies in sera of AIDS and pre-AIDS patients and describes the biochemical and immunological analysis of antigens associated with the virus HTLV-III Human T-Cell Leukemia Virus. It is shown that antigens associated with the infection of human cells by this virus are specifically recognized by antibodies from AIDS patients. Specifically, HTLV-III isolated from AIDS patients and transmitted by cocultivation with an HT cell line is specifically detected by antibodies from human sera taken from AIDS patients. The method of detection of antibodies preferred is a strip radioimmunoassay (RIA) based on the Western Blot technique or an ELISA (an enzyme-linked immunosorbent assay) or an indirect immunofluorescence assay.
摘要:
The invention relates to therapeutic polypeptides 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.
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.
摘要:
The present invention relates to methods of treating or preventing diseases or disorders associated with hematopoietic deficiency by administration of human chorionic gonadotropin, .beta.-human chorionic gonadotropin or a peptide containing a sequence of a portion of .beta.-human chorionic gonadotropin. The invention also relates to methods of treating or preventing diseases or disorders associated with hematopoietic deficiency by administration of hematopoietic cells, the numbers of which have been increased by contacting the cells with human chorionic gonadotropin, .beta.-human chorionic gonadotropin or a peptide containing a sequence of a portion of .beta.-human chorionic gonadotropin. The invention also provides assays for the utility of particular human chorionic gonadotropin preparations in the treatment or prevention of hematopoietic deficiencies or in the increasing of hematopoietic cell numbers in vitro. Pharmaceutical compositions and methods of administration of are also provided.
