    摘要: The present invention relates to a new human herpesvirus-7, proteins encoded in the genome of the virus, and antibodies specific for the virus and proteins. The virus was isolated from human peripheral blood mononuclear cells following incubation of the cells under conditions promoting T cell activation. Cultures of lymphocytes infected with the virus exhibited a cytopathic effect and electron microscopic analyses revealed a characteristic herpesvirus structure. The new virus is distinct from previously characterized human herpesvirus. The invention also relates to bioassays for the diagnosis of human herpesvirus-7 and the detection of human herpesvirus-7 in a biological sample. It further relates to a vaccine for humans against human herpesvirus-7.

    摘要: Novel methods for designing humanized immunoglobulins having one or more complementary determining regions (CDR's) from a donor immunoglobulin and a framework region from a human immunoglobulin comprising first comparing the framework or variable region amino acid sequence of the donor immunoglobulin to corresponding sequences in a collection of human immunoglobulin chains, and selecting as the human immunoglobulin one of the more homologous sequences from the collection. Each humanized immunoglobulin chain may comprise about 3 or more amino acids from the donor immunoglobulin in addition to the CDR's, usually at least one of which is immediately adjacent to a CDR in the donor immunoglobulin. The heavy and light chains may each be designed by using any one or all three additional position criteria. When combined into an intact antibody, the humanized immunoglobulins of the present invention will be substantially non-immunogenic in humans and retain substantially the same affinity as the donor immunoglobulin to the antigen, such as a protein or other compound containing an epitope.

    摘要: CR2 reactive polypeptides that correspond to amino acid residues in the amino terminal region of EBVgp350/220 and analogues thereof are described. Polypeptide sequences that correspond to at least 5 contiguous residues of the linear sequence of EBVgp350/220 and include at least one of residues 21-24 or 25-27 of the linear sequence bind to the CR2 receptor. Polypeptide aggregates comprising at least two CR2 reactive polypeptides find use as immunopotentiators, stimulating B cells. The aggregates also inhibit infection of B cells by EBV. Treatment methods and diagnostics are also described.
