  • Patent number: 5667965
    Abstract: This invention relates to E2 trans-activation repressors which interfere with normal functioning of the native full-length E2 transcriptional activation protein of the papillomavirus. Native full-length E2 trans-activation protein activates transcription of papillomavirus only through binding to DNA, and it binds to DNA only in the form of a pre-formed homodimer--a pair of identical polypeptide subunits held together by non-covalent interactions. The E2 trans-activation repressors of this invention are proteins, polypeptides or other molecules that dimerize with full-length native E2 polypeptides to form inactive heterodimers, thus interfering with the formation of active homodimers comprising full-length native E2 polypeptides, thereby repressing papillomavirus transcription and replication. The E2 trans-activation repressors of this invention are advantageously used in the treatment of papillomavirus infections and their associated diseases.

  • Patent number: 5661004
    Abstract: This invention relates to lymphotoxin-.beta., a lymphocyte membrane type protein. This protein is found on the surface of a number of cells, including phorbol ester (PMA) stimulated T cell hybridoma II-23.D7 cells. This invention also relates to complexes formed between lymphotoxin-.beta. and other peptides such as lymphotoxin-.alpha. and to complexes comprising multiple subunits of lymphotoxin-.beta.. These proteins and complexes are useful in holding LT-.alpha. formed within the cell on the cell surface where the LT-.alpha./LT.beta. complex may act as an inflammation regulating agent, a tumor growth inhibiting agent, a T cell inhibiting agent, a T cell activating agent, an autoimmune disease regulating agent, or an HIV inhibiting agent. Furthermore, the antitumor activity of the LT-.alpha./LT-.beta. complex may be delivered to tumor cells by tumor infiltrating lymphocytes (TILs) transfected with the gene for LT-.beta..
