Abstract:
In general, the invention features a method of purifying hematopoietic stem cells from swine, e.g., miniature swine, cord blood. The method includes collecting swine cord blood and purifying the hematopoietic stem cells from at least one other component of the swine cord blood. The swine cord blood hematopoietic stem cells can be used in methods of inducing tolerance in recipient mammals, e.g., humans, of a first species, to grafts obtained from the swine.
Abstract:
The invention provides a composition of matter, comprised of certain oligonucleotides, which inhibit the expression of beta /A4 peptide of Alzheimer's disease and Down's Syndrome, and nerve growth factor (NGF) to reverse morphological changes caused in neuronal cells by beta /A4 peptide. Further, pharmaceutical compositions, kits and methods for treatment of beta /A4 amyloid-induced morphology as well as an assay for screening candidate antisense oligonucleotides effective in treatment of deleterius effects that are visited upon cells by beta /A4 amyloid peptide are described.
Abstract:
A modified maxadilan protein exhibits higher biological activity than native maxadilan from the sand fly Lutzomyia longipalpis. A modified maxadilan fusion protein contains a thrombin cleavage site. This enables the production of the modified maxadilan as a fusion protein and recovery of the modified maxadilan after digestion with thrombin. The modified maxadilan is a potent vasodilator.
Abstract:
A method of identifying a therapeutic useful for treating or preventing Alzheimer's disease, which method includes the steps of contacting (a) a first molecule containing the couplone portion of APP (SEQ ID NO: 1) with (b) a second molecule containing the amino acid sequence of Go (SEQ ID NO: 2) or an APP-associating region of Go (SEQ ID NOs: 3, 4, or 5), in the presence of a candidate compound; and determining whether the candidate compound interferes with the association of the first and second molecules, such interference being an indication that the candidate compound is a potential Alzheimer's disease therapeutic.

Abstract:
A bacterial cell (preferably a gram-negative, enteric bacterium such as V. cholerae) the chromosome of which contains a DNA sequence encoding a heterologous antigen, which sequence is functionally linked to an iron-regulated promoter such as the irgA promoter of V. cholerae.
Abstract:
A method of treating proliferative diseases of the joint using photoactivatable compounds such as photofrin, benzoporphyrin derivatives or aminolevulinic acid in combination with light of the appropriate wavelength.
Abstract:
There are provided nucleic acid hybridization assays for RNA targets using RNA binary probes and a ribozyme ligase that is a stringent RNA-directed RNA ligase. Preferred assays include exponential amplification for signal generation. Tetrahymena ribozyme ligase is a preferred ligase for use in this invention. It may be tethered to hold it close to the ligation junction. One assay according to this invention is a ''tethered ligase chain reaction''. Also provided are kits for performing assays according to the invention.
Abstract:
A vaccine capable of protecting a recipient from infection caused by group B Streptococcus. The vaccine provides polysaccharide-protein moieties and contain (a) a group B Streptococcus polysaccharide conjugated to (b) a functional derivative of a group B Streptococcus C protein alpha antigen that retains the ability to elicit protective antibodies against group B Streptococcus. The vaccine may contain only one type of such polysaccharide-protein unit or may contain a mixture of more than one type of unit.
Abstract:
Disclosed is a method for determining whether a first protein is capable of physically interacting with a second protein. The method involves: (a) providing a host cell which contains (i) a reporter gene operably linked to a protein binding site; (ii) a first fusion gene which expresses a first fusion protein, the first fusion protein including the first protein covalently bonded to a binding moiety which is capable of specifically binding to the protein binding site; and (iii) a second fusion gene which expresses a second fusion protein, the second fusion protein including the second protein covalently bonded to a weak gene activating moiety; and (b) measuring expression of the reporter gene as a measure of an interaction between the first and the second proteins. Such a determination facilitates the isolation of the gene encoding the interacting protein. Also disclosed herein is recombinant Cdi1 polypeptide, nucleic acid encoding the Cdi1 polypeptide, and uses thereof.
Abstract:
A rapid, simple and inexpensive method to screen and classify proteins as partners of dimeric proteins is described. The method utilizes fusion protein constructs containing a DNA binding domain and complementary dimerization domains from a different protein. According to the method of the invention, protein partner heterodimer formation is detected by the ability of the protein partner to displace formation of DNA binding domain homodimers, and thus reveal a phenotypic change in a bacterial host which was dependent upon maintenance of the DNA binding domain homodimer configuration. The method of the invention may further be used to identify compounds of interest which inhibit such heterodimer formation, and especially to identify compounds which prevent heterodimer formation and activation of oncogenic transcriptional regulatory proteins.
