TMC1, a Deafness-Related Gene

Hearing loss is a common communication disorder affecting nearly 1 in 1,000 children in the United States alone, and nearly 50% of adults by the age of eighty. Hearing loss can be caused by environmental and disease-related factors; however, hearing loss due to genetic factors accounts for approximately 50% of cases.

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.

Phenylthiocarbamide (PTC) Taste Receptor

Bitter taste has evolved in mammals as a central warning signal against ingestion of poisonous or toxic compounds. However, many beneficial compounds are also bitter and taste masking of bitter tasting pharmaceutical compounds is a billion dollar industry. The diversity of compounds that elicit bitter-taste sensations is vast and more than two dozen members of the TAS2R bitter taste receptor gene family have been identified.

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.

Haplotypes of Human Bitter Taste Receptor Genes

Bitter taste has evolved in mammals as a crucial, important warning signal against ingestion of poisonous or toxic compounds. However, many beneficial compounds are also bitter, and taste masking of bitter tasting pharmaceutical compounds is a billion dollar industry. The diversity of compounds that elicit bitter-taste sensations is very large and more than two dozen members of the T2R bitter taste receptor family have been identified. Individuals are now known to be genetically predisposed to respond or not to respond to the bitter taste of a number of substances.

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.

Sensitive and Economic RNA Virus Detection Using a Novel RNA Preparation Method

DNA or RNA-based diagnostic tests for infectious diseases are critical in modern medicine. The current gold standard for COVID-19 detection is testing SARS-CoV-2 viral RNA by quantitative reverse transcription Polymerase Chain Reaction (RT-qPCR). This method involves patient sample collection with a nasopharyngeal swab, storage of the swab in a universal transport medium during transport to testing site, RNA extraction, and analysis of the extracted RNA sample.
