摘要:
The invention generally relates to a composition comprising an enriched NK cell population. The invention further relates to a method of treating a solid tumor or a hyperproliferative disorder by administering the enriched NK cell population to a mammalian subject in need thereof.
摘要:
One major problem in diagnosis methods presently available for anthrax is that these methods require several days to produce a result, are rendered unusable after antibiotic use, or are not quantifiable. The only existing treatment for anthrax requires administration soon after infection at a time when patients are exhibiting only mild flu-like symptoms. Thus, by the time a diagnosis is made a patient may be days beyond the time when treatment would be effective. The present invention reduces diagnosis time to as little as four hours providing same day identification of anthrax radically increasing the odds of delivering proper treatment and patient recovery. The rapid identification of anthrax edema factor activity exhibited by the invention is also amenable to in vivo screening protocols for the discovery and development of anthrax vaccines, anti-toxins and edema factor inhibitors. The invention isolates and concentrates edema factor and edema toxin from nearly any sample. By capitalizing on the adenylate cyclase activity of edema factor the invention amplifies output signals producing reliable detection of low concentrations of edema factor previously unachievable. The invention involves novel purification and detection techniques and substrates for rapid, reproducible, and quantitative measurements of anthrax edema factor, and other adenylate cyclases in biological samples.
摘要:
The present invention relates to Salmonella typhi Ty21a a comprising core-linked Shigella dysenteriae type 1 O-specific polysaccharide (O-Ps) and DNA encoding O antigen biosynthesis, said DNA selected from the group consisting of: a) the DNA sequence set out in any one of SEQ ID NOs: 1 and 2; b) DNA encoding S. dysenteriae serotype 1 biosynthesis polypeptides encoded by any one of SEQ ID NOs: 1 and 2; c) DNA encoding variants of the polypeptide encoded by the DNA of (a) or (b), wherein the variants comprise O antigen biosynthesis polypeptide analogs, wherein one or more of the specified amino acids is deleted or replaced, or wherein one or more non-specified amino acids are added without loss of biosynthesis of Shigella dysenteriae serotype 1 O antigen or protective immunological activity of the O antigen biosynthesis gene product; and d) nucleic acid molecules encoding gene products that share at least about 90% sequence identity with the polypeptide encoded by the nucleic acid molecule of SEQ ID NO: 1 or 2.
摘要:
The invention generally relates to postnatal periodontal ligament stem cells and methods for their use. More specifically, the invention relates in one aspect to postnatal periodontal ligament multipotent stem cells, use of the cells to generate periodontium, differentiation of the cells and methods of tissue cryopreservation.
摘要:
The present invention relates to a method of stabilizing an insert in a recombinant vaccinia virus by disrupting a run of 4 or more G or C residues through a substitution that introduces a silent mutation in the run, the length of which is thereby reduced.
摘要:
Immunogenic polypeptides corresponding to one or more RSV G glycoproteins, or analogues thereof, are provided as components of vaccines. The inventive compositions are useful as both a prophylactic and therapeutic for the prevention and treatment of RSV infections and associated pulmonary or other diseases. The inventive immunogens include regions of the RSV G protein, specifically, amino acid residues 164-176 of RSV G A2 protein or analogues thereof. This inventive immunogen is operable alone or in combination with other polypeptides such as the RSV G protein amino acid residues 155-206, or other vaccines such as live RSV vaccines, or inactivated RSV vaccines or immunogenic analogues thereof.

摘要:
The invention relates to nucleic acids (such as DNA immunization plasmids), encoding fusion proteins containing a destabilizing amino acid sequence attached to an amino acid sequence of interest, in which the immunogenicity of the amino acid sequence of interest is increased by the presence of the destabilizing amino acid sequence. The invention also relates to nucleic acids encoding secreted fusion proteins, such as those containing chemokines or cytokines, and an attached amino acid sequence of interest, in which the immunogenicity of the amino acid sequence of interest is increased as a result of being attached to the secretory sequence. The invention also relates methods of increasing the immunogenicity of the encoded proteins for use as vaccines or in gene therapy.
