Treatment and Prevention of Inflammatory Bowel Disease (IBD) using Mutant and Chimeric IL-13 Molecules

Ulcerative colitis (UC) is a chronic inflammatory disease of the colorectum and affects approximately 400,000 people in the United States. The cause of UC is not known, although an abnormal immunological response to bacterial antigens in the gut microflora is thought to be involved. Present treatments for UC include anti-inflammatory therapy using aminosalicylates or corticosteroids, as well as immunomodulators and diet.

Molecules for Studying Cellular Immune Responses to Vaccines and Therapeutics

HLA molecules are indispensable and invaluable tools for efficient vaccine research and development. Infectious diseases are the second leading cause of death among adults and the most prominent cause of death in infants and children worldwide. Thus, rapid availability of prophylactic vaccines for cancers and infectious diseases such as HIV, HPV, influenza and diarrheal and respiratory diseases is a world-wide health concern.

Neutralizing Monoclonal Antibodies to Botulinum Neurotoxin Type A

Two chimpanzee mAbs specifically reacted with light chain of the botulinum neurotoxin A and neutralize the toxin in the mouse model. They can be used for emergency prophylaxis and treatment of either naturally acquired or terrorist associated botulism. Since the sequence of chimpanzee immune globulin is virtually identical to that of humans, the MAbs are not expected to have problems in repeated administration as equine antibodies. They can also be used for rapid diagnosis of botulinum neurotoxin A.

Serotonin-Deficient Knock-out Mouse

Serotonin is an important modulator of many developmental, behavioral, and physiological processes, and it has been implicated in depression, anxiety, schizophrenia, obsessive compulsive disorders, and substance abuse. Serotonin’s pharmacology is extremely complex and it is mediated by seven of serotonin receptor subtypes and it is present in several tissues. Although it has been a subject of a number of studies, its role has been difficult to ascertain. To investigate the role of serotonin in these disorders, the murine gene was disrupted by homologous recombination.

High Level Expression and Purification of Untagged and Histidine-tagged Human Immunodeficiency Virus Type-1 Reverse Transcriptase

Human immunodeficiency virus type-1 reverse transcriptase (HIV-1 RT) gene encodes 560 amino acids. In the virus, however, HIV-1 RT occurs as a dimer of two related polypeptides, p66 and p51 subunits at a molar ratio of 1:1. The p51 subunit is derived from a C-terminal proteolytic cleavage of the p66 subunit. This invention describes a simplified protocol to purify large quantities of histidine-tagged and untagged heterodimeric forms of human immunodeficiency virus type-1 reverse transcriptase (HIV-1 RT) from Escherichia coli.

Retrovirus Packaging Cell Lines Based on Gibbon Ape Leukemia Virus

Gene therapy and gene transfer have recently been recognized as effective therapeutic tools to combat diseases. Accordingly, market demands for vectors and carriers to facilitate such interventions have surged in recent years. Retroviral vectors provide an efficient and safe means of gene transfer to eukaryotic cells. The present invention relates to genetic engineering involving retrovirus packaging cells that produce retroviral vectors.

Immunotoxin with in-vivo T cell Suppressant Activity

The invention concerns immunotoxins and methods of using the immunotoxins for the treatment of autoimmune diseases and T cell malignancies. The immunotoxins are targeted via an antibody that is specific to T cells. This allows the specific ablation of malignant T cells and resting T cells. The transient ablation of resting T cells can "reset" the immune system by accentuating tolerizing responses. The toxin portion of the immunotoxin is genetically engineered to maintain bioactivity when recombinantly produced in Pichia pastoris.
