Method of Diagnosing Multidrug Resistant Tuberculosis

The invention can be used to develop tests that are much more rapid than conventional tests for determining drug resistance. It relates to the discovery that a putative gene of Mycobacterium tuberculosis (MTb) with no previously identified function is responsible for the ability of the bacteria to activate a class of second line thioamide drugs used for MTb infections. The gene, termed "etaA", codes for the synthesis of a monooxygenase, the enzyme responsible for the oxidative activation of the drugs.

Anti-Plasmodium Compositions and Methods of Use

This invention describes methods and compositions of peptides that inhibit the binding of Plasmodium falciparum (P. falciparum) to erythrocytes. Malarial parasites enter the red blood cell through several erythrocyte receptors, each being specific for a given species of Plasmodia. For P. falciparum, the erythrocyte binding antigen (EBA-175) is the ligand of the plasmodia merozoites that interacts with the receptor glycophorin A on the surface of red blood cells.

Method for Inducing T-Cell Proliferation

This technology relates to the use of thymic stromal lymphopoietin (TSLP) to induce CD4+ T cell proliferation. This proliferation could be of particular relevance for patients in whom this cell population has been significantly reduced by HIV/AIDS or other conditions resulting in immunodeficiency. The proliferation of isolated CD4+ T cells can be induced through direct contact with TSLP or a nucleic acid encoding TSLP.

Monoclonal Antibodies That Bind or Neutralize Hepatitis B Virus

Hepatitis B virus (HBV) chronically infects over 300 million people worldwide. Many of them will die of chronic hepatitis or hepatocellular carcinoma. The present technology relates to the isolation and characterization of a novel neutralizing chimpanzee monoclonal antibody to HBV. The antibody was identified through a combinatorial antibody library constructed from bone marrow cells of a chimpanzee experimentally infected with HBV. The selected monoclonal antibody has been shown to react equally well with wild-type HBV and the most common neutralization escape mutant variants.

Methods and Compositions for the Inhibition of SARS-CoV Replication Propagation and Transmission

Available for licensing and commercial development is a method of inhibiting SARS-CoV replication, propagation and transmission using 2-cyano-3,12-dioxooleana-1,9-dien-28-oic (CDDO). Severe acute respiratory syndrome (SARS) is an infectious atypical pneumonia that has recently been recognized in patients in 32 countries and regions. The atypical pneumonia with unknown etiology was initially observed in Guangdong Province, China.

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.

Swine Hepatitis E Virus Available For Use in Diagnosis, Prevention and Treatment of Hepatitis E

Hepatitis E virus (HEV) is the cause of Hepatitis E, a liver disease that occurs primarily in developing countries due to fecal contaminated drinking water. Outbreaks of HEV infection have caused epidemics in Africa, Central and Southeast Asia and Mexico and cases of the disease have also been reported sporadically in more developed countries. Hepatitis E is most often overcome by a host’s natural defenses; however the disease is more severe in pregnant women, who exhibit a 20% mortality rate due to HEV infection.

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.

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.
