A 'localizable' systemic gene therapy system is provided substantially increasing the transfection efficiency of the gene vectors into targeted tissue cells and substantially reducing the escape of the gene vectors from the targeted tissue volume, such as would waste the vectors, promote undesired immune reactions, and/or incur prohibitive costs for the required dose of gene-containing virus vectors. In this regard, the invention provides a means to simultaneously achieve local electroporation and gene-containing vector injection in a portion of a vascularized organ. It includes two double-balloon catheters that create contained volumes in parallel blood vessels for the introduction of vectors with reduced loss along with electrodes providing electroporation of the cells in the same location where the vectors are injected.

In vivo gene therapy delivery procedure and device

A method and vectors for controlling blood glucose levels in a mammal are disclosed. In one embodiment, the method comprises the steps of: treating the hepatocyte cells of a patient with a first, second or third vector, wherein the first vector comprises a promoter enhancer, glucose inducible regulatory elements, a liver-specific promoter, a gene encoding human insulin with modified peptidase and an albumin 3'UTR and lacks an HGH intron, wherein the second vector comprises an HGH intron, glucose inducible regulatory elements, a liver-specific promoter, a gene encoding human insulin with modified peptidase site and an albumin 3′UTR and lacks a promoter enhancer, wherein the third vector comprises an HGH intron, glucose inducible regulatory elements, a liver-specific promoter, a gene encoding human insulin with modified peptidase site, an albumin 3′UTR and a promoter enhancer and observing the patient's insulin levels, wherein the patient's insulin levels are controlled.

Hepatocyte based insulin gene therapy for diabetes

In vivo therapeutic delivery procedure and device

A method and vectors for controlling blood glucose levels in a mammal are disclosed. In one embodiment, the method comprises the steps of: treating the hepatocyte cells of a patient with a first, second or third vector, wherein the first vector comprises a promoter enhancer, glucose inducible regulatory elements, a liver-specific promoter, a gene encoding human insulin with modified peptidase and an albumin 3'UTR and lacks an HGH intron, wherein the second vector comprises an HGH intron, glucose inducible regulatory elements, a liver-specific promoter, a gene encoding human insulin with modified peptidase site and an albumin 3&#x2032;UTR and lacks a promoter enhancer, wherein the third vector comprises an HGH intron, glucose inducible regulatory elements, a liver-specific promoter, a gene encoding human insulin with modified peptidase site, an albumin 3&#x2032;UTR and a promoter enhancer and observing the patient's insulin levels, wherein the patient's insulin levels are controlled.

The invention relates to methods, compositions, and kits for detection of biomarkers. In one embodiment, the invention relates to a method for detecting AMR biomarkers in a biological sample. In another embodiment, the invention relates to a method for detecting, monitoring, diagnosing and predicting antibody mediated rejection. In yet another embodiment, the invention relates to a method for monitoring a subject for antibody mediated rejection comprising detecting BAFF or a BAFF variant in a biological sample. In still another embodiment, the invention relates to a kit for detecting BAFF in a urine sample.

Detection of B-cell activating factor as a biomarker for antibody mediated rejection in transplant recipients

Disclosed is a method for obtaining glucose-regulated expression of active insulin in the cells of a mammalian subject. The method involves delivering into the subject a genetic construct comprising a coding sequence for a human proinsulin operably connected a promoter functional in the host cells. The construct includes a glucose responsive regulatory module having at least one glucose inducible regulatory element comprising a pair of CACGTG motifs linked by a five base nucleotide sequence, which confers glucose inducible expression of the proinsulin coding sequence. To ensure proper processing of the proinsulin to active insulin, the coding sequence was modified to direct the synthesis of a mutant proinsulin polypeptide having amino acid sequences that can be cleaved to mature insulin in suitable host cells, such as hepatocytes.

Treatment of diabetes with synthetic beta cells

A method of moderating transplant rejection in a transplant recipient comprising administering a dose of vitamin D compound effective to prevent transplant rejection is disclosed. Preferably, the recipient's susceptibility to opportunistic infections has not been compromised. Also preferably, the recipient has not suffered bone demineralization.
