A Novel Treatment for Malarial Infections

The inventions described herein are antimalarial small molecule inhibitors of the plasmodial surface anion channel (PSAC), an essential nutrient acquisition ion channel expressed on human erythrocytes infected with malaria parasites. These inhibitors were discovered by high-throughput screening of chemical libraries and analysis of their ability to kill malaria parasites in culture. Two separate classes of inhibitors were found to work synergistically in combination against PSAC and killed malaria cultures at markedly lower concentrations than separately.

Therapeutic Methods Based on In Vivo Modulation of the Production of Interferon gamma

The technology offered for licensing is in the field of Therapeutics. More specifically, the technology relates to biological ligands and their use as modulators of the production of Interferon gamma as a means to treat a broad spectrum of diseases. The invention describes and claims antibodies and other ligands that can stimulate Natural Killer (NK) immune cells to produce Interferon gamma which contributes to the combat against foreign pathogens.

MDCK Cells with Enhanced Characteristics for Vaccine and Virus Production

This technology relates to compositions and methods for improving the growth characteristics of cells engineered to produce live viruses such as the Influenza virus. Featured is a method that uses the gene candidate, siat7e, or its expressed or inhibited products in Madin Darby Canine Kidney (MDCK) cells. The gene expression modulates anchorage-dependence of the cell line thereby allowing scale-up on bioreactor platforms without the use of microcarrier beads and reducing production costs.

qPCR Assay for Detection of JC Virus

JC Virus causes a fatal disease in the brain called progressive multifocal leukoencephalopathy (PML) that occurs in many patients with immunocompromised conditions. For example, more than five percent (5%) of AIDS patients develop PML. Additionally, these conditions include, but are not limited to, cancers such as leukemias and lymphomas, organ transplants such as kidney, heart and autoimmune conditions with treatment that modulates the immune system such as Multiple Sclerosis (MS), rheumatoid arthritis, psoriasis, and systemic lupus erythematosus.

Vaccines Against Malarial Diseases

The invention offered for licensing is in the field of use of vaccines for malaria. The invention provides gene sequences encoding an erythrocyte binding protein of a malaria pathogen for the expression of the erythrocyte binding protein. The codon composition of the synthetic gene sequences approximates the mammalian codon composition. The synthetic gene sequences are useful for incorporation into DNA vaccine vectors, for the incorporation into various expression vectors for production of malaria proteins, or both.

Device for Selective Partitioning of Frozen Cellular Products

Cryopreservation using liquid nitrogen frozen polyvinyl bags allows for storing cellular materials for extended periods while maintaining their activity and viability. Such bags are commonly used in the clinic to store blood products including blood cells, plasma, hematopoietic stem cells, umbilical cord blood for future uses including transplantation. These materials, typically obtained in limited quantities, may be of great therapeutic value, as is the case of stem cells or cord blood derived cells which can be used to potentially treat a number of diseases.

Erythroid Progenitor Cell Line for Hematological Disease Applications

Plasmodium vivax (malaria) is a significant health concern in many parts of Asia, Latin America, North Africa, and the Middle East. There is a lack of continuous culture systems for this pathogen. The subject technology is an erythroid progenitor continuous cell line (termed CD36E) identified by erythroid markers CD36, CD33, CD44, CD71, CD235, and globoside. These CD36E cells are heterozygous for Fya and Fyb (Duffy antigen). Due to recent evidence that Plasmodium vivax (P. vivax) can infect erythroid progenitor cells (reference: YX Ru et al.

Parvovirus B19 Codon Optimized Structural Proteins for Vaccine and Diagnostic Applications

Parvovirus B19 (B19V) is the only known pathogenic human parvovirus. Infection by this viral pathogen can cause transient aplastic crisis in individuals with high red cell turnover, pure red cell aplasia in immunosuppressed patients, and hydrops fetalis during pregnancy. In children, B19V most commonly causes erythema infectiosum, or fifth's disease. Infection can also cause arthropathy and arthralgia. The virus is very erythrotropic, targeting human erythroid (red blood) progenitors found in the blood, bone marrow, and fetal liver.

Full-Length Infectious cDNA Clones of Tick Borne Flavivirus

The tick-borne encephalitis virus complex of flavivirus family includes tick-borne encephalitis (TBEV), Kyasanur forest disease, Langat, Louping ill, Negishi, Omsk hemorrhagic fever and Povassan viruses. These viruses are endemic throughout most of the Northern Hemisphere and except for Langat, cause human disease of varying severity that can have mortality as high as 20 to 30%.
