Vaccination Strategies to Provide Protection Against the Ebola Virus

This invention describes a method for vaccination against Ebola virus. Outbreaks of hemorrhagic fever caused by the Ebola virus, particularly the Zaire subtype, are associated with high mortality rates. The virus is very contagious, and during an outbreak, presents a threat to anybody who comes into contact with an infected person. Because the virus progresses so rapidly and the mortality rate is so high, there is little opportunity to develop natural immunity, making vaccination a promising intervention.

Live Attenuated Vaccine to Prevent Disease Caused by West Nile Virus

West Nile virus (WNV) has recently emerged in the U.S. and is considered a significant emerging disease that has embedded itself over a considerable region of the U.S. WNV infections have been recorded in humans as well as in different animals. From 1999-2014, WNV killed 1,765 people in the U.S. and caused severe disease in more than 41,762 others. This project is part of NIAID's comprehensive emerging infectious disease program.

Dengue Tetravalent Vaccine Containing a Common 30 Nucleotide Deletion in the 3'-UTR of Dengue Types 1, 2, 3, and 4

The invention relates to a dengue virus tetravalent vaccine containing a common 30-nucleotide deletion (delta30) in the 3'-untranslated region (UTR) of the genome of dengue virus serotypes 1, 2, 3, and 4. The previously identified delta30 attenuating mutation, created in dengue virus type 4 (DEN4) by the removal of 30 nucleotides from the 3'-UTR, is also capable of attenuating a wild-type strain of dengue virus type 1 (DEN1).

Peptide Mimotope Candidates for Otitis Media Vaccine

This technology describes peptide mimotopes of lipooligosaccharides (LOS) from nontypeable Haemophilus influenzae (NTHi) and Moraxella catarrhalis that are suitable for developing novel vaccines against the respective pathogens, for which there are currently no licensed vaccines. The mimotopes not only immunologically mimic LOSs from NTHi and M. catarrhalis but will also bind to antibodies specific for the respective LOS. NTHi and M. catarrhalis are common pathogens that cause otitis media in children and lower respiratory tract infections in adults.

A Key Advancement for Human Norovirus Research and Reverse Genetics

The HEK293T/T7 cell line is a novel development in virology research, particularly for studying human noroviruses. This cell line expresses the T7 RNA polymerase, a key enzyme used in reverse genetics systems. Unlike existing technologies, the HEK293T/T7 cell line offers the unique advantage of being able to produce functional T7 RNA polymerase, which is essential for driving transcription from T7 promoters.

Novel Antigen for Use as Vaccine Against Nematode Infection

This invention describes a new vaccine against Strongyoides stercoralis, which establishes a parasitic infection that affects an estimated 100-200 million people worldwide. The potential for fatal disease associated with S. stercoralis infection and the difficulty in treating hyperinfection underscores the need for prophylactic vaccines against the disease. This vaccine uses S. stercoralis immunoreactive antigen (SsIR); a novel antigen capable of providing 70-90 % protection for mice immunized with the antigen.

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.
