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.

Stem Cell Factor-responsive FcepsilonRI Bearing Human Mast Cell Line LAD2

A human mast cell line LAD2 that more closely resembles normal in vivo and in vitro human mast cells by expressing functional FcepsilonRI receptors and responding to stem cell factor (SCF) with proliferation, as described in Leuk Res. 2003 Aug;27(8):677-82 and developed by the laboratory of Dr. Dean Metcalfe at the National Institute of Allergy and Infectious Diseases.  This cell line also releases mediators by cross-linking FcgammaRI (CD64) receptors and express FcgammaRII (CD32).

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).

Mouse Monoclonal Antibodies Against Human IKKgamma/NEMO Protein

NF-kB has been found to be important in immune responses, cell proliferation, apoptosis, and in organ development. Several years ago it was discovered that an IKKgamma/NEMO protein was essential as an adaptor molecule to mediate TNF-alpha, IL-1, and oncoprotein induced activation of NF-kB. Mutation in IKKgamma/NEMO also results in two human genetic diseases, Familial incontinentia pigmenti and hypohidrotic/anhidrotic ectodermal dysplasia. The NIH announces mouse monoclonal antibodies to IKKgamma/NEMO that are far superior to other immunological reagents.

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.

Construction of Recombinant Baculoviruses Carrying the Gene Encoding the Major Capsid Protein, VP1, From Calicivirus Strains (Including Norovirus Strains Toronto, Hawaii, Desert Shield, Snow Mountain, and MD145-12)

The noroviruses (known as "Norwalk-like viruses") are associated with an estimated 23,000,000 cases of acute gastroenteritis in the United States each year. Norovirus illness often occurs in outbreaks, affecting large numbers of individuals, illustrated recently by well-publicized reports of gastroenteritis outbreaks on several recreational cruise ships and in settings such as hospitals and schools. Norovirus disease is clearly important in terms of medical costs and missed workdays, and accumulating data support its emerging recognition as important agents of diarrhea-related morbidity.

Soluble Antigen-Based ELISA for the Detection of B. malayi Infections

The technology presented is a breakthrough in the diagnosis of lymphatic filariasis, specifically targeting the B. malayi pathogen. It encompasses a novel soluble antigen extract used in both IgG and IgG4-based ELISA tests, aimed at detecting the presence of the filarial infection. This innovation serves as a cornerstone for a CLIA-certified reference test, established and utilized in Dr. Nutman's laboratory since the late 1980s.

Diagnostic Assays and Methods of Use for Detection of Filarial Infection

The effort targeting the mosquito borne neglected tropical disease lymphatic filariasis for elimination through mass drug administration by 2020 will require accurate, cost effective methods for detecting early infections. The World Health Organization-recommended immunochromatographic test detects adult Wuchereria bancrofti (Wb) antigen in blood, but shows variable efficacy due to the complex life cycle of the parasites and cross reactivity with other organisms. This variability may hinder effective lymphatic filariasis elimination efforts.

Antibodies and Methods for the Diagnosis and Treatment of Epstein-Barr Virus Infection

According to the World Health Organization, over 90% of the worldwide population is infected with Epstein-Barr virus by adulthood. In most cases, the disease accompanying initial infection is subclinical though some individuals who are infected as adolescents or adults do experience infectious mononucleosis. However, once infected, individuals carry latent EBV for their remaining lifespan. In such individuals, immune suppression can result in reactivation of the EBV and consequently, EBV-associated lymphoproliferative disease.

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.
