Codon-optimization of HIV-1 Viral Infectivity Factor (VIF) Gene

Expression of the HIV-1 Vif protein in the absence of other viral factors such a Tat and Rev is extremely inefficient due to the presence of inhibitory sequences on its mRNA. This invention uses codon optimization to remove such inhibitory sequences without altering the amino acid sequence of the protein. The modified vif gene in the resulting pcDNA -hVIF vector is expressed under the control of the CMV promoter. In this, the protein functions as wild type and is more amendable to high-level expression in mammalian cells.

IL-21 Critically Regulates Immunoglobulin Production

The invention includes a mouse in which the IL-21 receptor gene is disrupted by homologous recombination, the disruption being sufficient to prevent expression of the IL-21 receptor and thus to inhibit the action of IL-21. The invention also includes a mouse in which both the IL-21 receptor gene and the IL-4 gene are simultaneously disrupted in fashions being sufficient to inhibit the action of IL-21 and the production of IL-4. In a homozygous state, these mutations produce a mouse that has diminished B cell function.

Cloning and Characterization of an Avian Adeno-Associated Virus and Uses Thereof

Currently, adeno-associated virus (AAV) represents the gene therapy vehicle of choice because it has many advantages over current strategies for therapeutic gene insertion. AAV is less pathogenic than other virus types; stably integrates into dividing and non-dividing cells; integrates at a consistent site in the host genome; and shows good specificity towards various cell types for targeted gene delivery.

Brother of the Regulator of Imprinted Sites (BORIS)

The subject application discloses an isolated or purified nucleic acid molecule consisting essentially of a nucleotide sequence encoding a human or a non-human BORIS, or a fragment of either of the foregoing; an isolated or purified nucleic acid molecule consisting essentially of a nucleotide sequence that is complementary to a nucleotide sequence encoding a human or a non-human BORIS, or a fragment of either of the following; a vector comprising such an isolated or purified polypeptide molecule consisting essentially of an amino acid sequence encoding a human or a non-human BORIS, or a fragme

Activation of Recombinant Diphtheria Toxin Fusion Proteins by Specific Proteases Highly Expressed on the Surface of Tumor Cells

This invention relates to diphtheria toxin fusion proteins comprising a diphtheria toxin (DT) cell-killing component and a cell-binding component such as granulocyte macrophage colony-stimulating factor (GM-CSF), interleukin 2 (IL-2), or epidermal growth factor (EGF). Receptors for the latter three materials are present on many types of cancer cells; therefore, these fusion proteins bind preferentially to these cancer cells. A key feature is that these toxins are altered so as to require activation by a cell-surface protease that is overexpressed on many types of cancers.

Method for the Treatment of Multiple Sclerosis

The invention relates to the discovery that humanized antibodies to the interleukin-2 receptor (IL-2R) such as (daclizumab) are effective in treating multiple sclerosis (MS). In particular, it has been discovered that patients who have failed to respond to therapy with interferon-beta show dramatic improvement when treated with daclizumab, with patients showing both a reduction in the total number of lesions and cessation of appearance of new lesions during the treatment period. Daclizumab is effective both in combination with interferon-beta and alone.

Multipotent Postnatal Stem Cells From Human Periodontal Ligament and Uses Thereof

It is estimated that over 40 percent of the adult population in the United States has periodontal disease in one form or another. Periodontal Disease is a chronic infection of the periodontal ligament (PDL) and the adjacent bone and cementum. The effects of Periodontal Disease range from simple gum inflammation to, in extreme cases, tooth loss.

Enzymatically-Active RNA-Dependent RNA Polymerase From a Human Norovirus (Calicivirus)

The noroviruses (formerly known as “Norwalk-like viruses”) are associated with gastroenteritis outbreaks, affecting large numbers of individuals each year. Emerging data are supporting their increasing recognition as important agents of diarrhea-related morbidity and mortality. The frequency with which noroviruses are associated with gastroenteritis as “food and water-borne pathogens” has led to the inclusion of caliciviruses as Category B Bioterrorism Agents/Diseases.

Construction of an Infectious Full-Length cDNA Clone of the Porcine Enteric Calicivirus RNA Genome

Porcine enteric calicivirus (PEC) is a member of the genus Sapovirus in the family Caliciviridae. This virus causes diarrheal illness in pigs, and is presently the only enteric calicivirus that can be grown in cell culture. In addition to its relevance to veterinary medicine as a diarrheal agent in pigs, PEC serves as an important model for the study of enteric caliciviruses that cause diarrhea and that cannot be grown in cell culture (including the noroviruses represented by Norwalk virus).

Cannula for Pressure Mediated Drug Delivery

Available for licensing are methods and devices for selectively delivering therapeutic substances to specific histological or microanatomical areas of organs (e.g., introduction of the therapeutic substance into a hollow organ space such as the hepatobiliary duct or the gallbladder lumen) at a controlled pressure, volume and/or rate which allows the substance to reach a predetermined cellular layer.
