Zetakines, when expressed on the surface of T lymphocytes, direct T cell activity to those specific cells expressing a receptor for which the soluble receptor ligand is specific.

In a preferred embodiment is a glioma-specific immunoreceptor comprising the extracellular targeting domain of the IL-13Rα2-specific IL-13 mutant IL-13(E13Y) linked to the Fc region of IgG, the transmembrane domain of human CD4, and the human CD3 zeta chain. | 09-15-2011 |

| 20110124051 | PYROPHOSPHOROLYSIS ACTIVATED POLYMERIZATION (PAP) - A novel method of pyrophosphorolysis activated polymerization (PAP) has been developed. In PAP, pyrophosphorolysis and polymerization by DNA polymerase are coupled serially for each amplification by using an activatable oligonucleotide P* that has a non-extendible 3′-deoxynucleotide at its 3′ terminus. PAP can be applied for exponential amplification or for linear amplification. PAP can be applied to amplification of a rare allele in admixture with one or more wild-type alleles by using an activatable oligonucleotide P* that is an exact match at its 3′ end for the rare allele but has a mismatch at or near its 3′ terminus for the wild-type allele. PAP is inhibited by a mismatch in the 3′ specific sequence as far as 16 nucleotides away from the 3′ terminus. PAP can greatly increase the specificity of detection of an extremely rare mutant allele in the presence of the wild-type allele. Specificity results from both pyrophosphorolysis and polymerization since significant nonspecific amplification requires the combination of mismatch pyrophosphorolysis and misincorporation by the DNA polymerase, an extremely rare event. Using genetically engineered DNA polymerases greatly improves the efficiency of PAP. | 05-26-2011 |

| 20110046208 | NUCLEOLAR TARGETING OF THERAPEUTICS AGAINST HIV - The HIV regulatory proteins Tat and Rev accumulate in nucleoli of human cells. No functional role has been attributed to this localization. Recently it was demonstrated that expression of Rev induces nucleolar re-localization of some nuclear factors involved in Rev export. Thus, it is likely that the nucleolus plays a critical role in Rev-mediated export of singly spliced and unspliced HIV-1 RNAs. As a test for trafficking of HIV-1 RNAs into the nucleolus, a hammerhead ribozyme which specifically cleaves HIV-1 RNA was joined to the U16 snoRNA resulting in accumulation of the ribozyme within nucleoli of human cells. Stably transduced human T-cells expressing this nucleolar localized ribozyme dramatically suppressed HIV-1 replication, confirming a possible trafficking of the HIV RNA through the nucleoli of human cells. In addition, a TAR element which binds Tat was joined to the U16 snoRNA, also resulting in localization in the nucleoli and inhibiting HIV replication. | 02-24-2011 |

| 20090239283 | PYROPHOSPHOROLYSIS ACTIVATED POLYMERIZATION (PAP) - A novel method of pyrophosphorolysis activated polymerization (PAP) has been developed. In PAP, pyrophosphorolysis and polymerization by DNA polymerase are coupled serially for each amplification by using an activatable oligonucleotide P* that has a non-extendible 3′-deoxynucleotide at its 3′ terminus. PAP can be applied for exponential amplification or for linear amplification. PAP can be applied to amplification of a rare allele in admixture with one or more wild-type alleles by using an activatable oligonucleotide P* that is an exact match at its 3′ end for the rare allele but has a mismatch at or near its 3′ terminus for the wild-type allele. PAP is inhibited by a mismatch in the 3′ specific sequence as far as 16 nucleotides away from the 3′ terminus. PAP can greatly increase the specificity of detection of an extremely rare mutant allele in the presence of the wild-type allele. Specificity results from both pyrophosphorolysis and polymerization since significant nonspecific amplification requires the combination of mismatch pyrophosphorolysis and misincorporation by the DNA polymerase, an extremely rare event. Using genetically engineered DNA polymerases greatly improves the efficiency of PAP. | 09-24-2009 |
| 20090191172 | Method of Controlling Administration of Cancer Antigen - The present invention is directed to mammalian bi-specific T cells and methods for using these bi-specific T cells.

| 20090087839 | LONG DISTANCE POLYMERASE CHAIN REACTION-BASED ASSAY FOR DETECTING CHROMOSOMAL REARRANGEMENTS - Methods are presented for determining the presence of an inversion in the factor VIII gene which cause hemophilia A. The methods encompass long distance, multiplex PCR (including overlapping PCR). The use of deaza-dGTP, high levels of DNA polymerases and high levels of DMSO aid in successfully performing the PCR. The use of a novel technique called subcycling PCR can also be applied as part of the methods. The technique allows for the determination of whether a person is homozygous or hemizygous for the inversion and has hemophilia A or whether a person is heterozygous for the inversion and is a carrier. The technique of long distance, multiplex PCR including use of deaza-dGTP, high levels of DNA polymerases and high levels of DMSO are applicable to the determination of the presence of other gross chromosomal aberrations such as deletions/inversions, translocations and inversions. The use of subcycling PCR can achieve efficient and more even amplification than normal two or three temperature PCR and is applicable to long distance, multiplex PCR. | 04-02-2009 |
| 20090043085 | METHODS AND COMPOSITIONS FOR THE SPECIFIC INHIBITION OF GENE EXPRESSION BY DOUBLE-STRANDED RNA - The invention is directed to compositions and methods for selectively reducing the expression of a gene product from a desired target gene in a cell, as well as for treating diseases caused by the expression of the gene. More particularly, the invention is directed to compositions that contain double stranded RNA (“dsRNA”), and methods for preparing them, that are capable of reducing the expression of target genes in eukaryotic cells. The dsRNA has a first oligonucleotide sequence that is between 25 and about 30 nucleotides in length and a second oligonucleotide sequence that anneals to the first sequence under biological conditions. In addition, a region of one of the sequences of the dsRNA having a sequence length of at least 19 nucleotides is sufficiently complementary to a nucleotide sequence of the RNA produced from the target gene to trigger the destruction of the target RNA by the RNAi machinery. | 02-12-2009 |
