This technology provides a new set of hybridoma cell lines each expressing a single monoclonal antibody against human respiratory syncytial virus (RSV) nonstructural protein 1 (NS1). These antibodies have variously been shown to detect NS1 protein in an enzyme-linked immunosorbent assay (ELISA), Western blot assay, immunofluorescence microscopy of paraformaldehyde-fixed cells, and flow cytometry. The various antibodies can vary in their efficiency in each of these assays.

Acute respiratory infections during early childhood constitute a major human health burden. Human respiratory syncytial virus (RSV) is the most common and important viral cause of severe acute pediatric respiratory infections worldwide. Mortality due to RSV in the post-neonatal (28 days to 1 year old) population is second only to malaria. It is estimated that RSV causes 34 million lower respiratory tract infections, 4 million hospitalizations, and 66,000-199,000 deaths every year in children less than 5 years of age.

RSV is the most important viral agent of severe respiratory tract disease worldwide, especially in infants and young children, and it also causes severe disease in the elderly and in immunocompromised individuals. There are no licensed vaccines or antivirals suitable for routine use.

Human metapneumovirus (hMPV), a negative, single-stranded RNA virus, accounts for approximately 5-15% of infant respiratory tract infections and poses a severe risk of disease and hospitalization in both the elderly and the immunocompromised. Investigators at the Vaccine Research Center (VRC) of the National Institute of Allergy and Infectious Diseases (NIAID) have generated an hMPV fusion glycoprotein (“F protein”) stabilized in a prefusion conformation.

Mycobacterium tuberculosis (Mtb) infection continues to be the leading cause of death due to a single infectious agent and poses significant global health challenges. Past research has shown that CD4 T cells are essential for resistance to Mtb infection, and for decades it has been thought that IFN(?) production is the primary mechanism of CD4 T cell-mediated protection.

Middle East Respiratory Syndrome coronavirus (MERS-CoV) causes a highly lethal pulmonary infection with ~35% mortality. Currently there are no prophylactic measures or effective therapies. Inventors at the Vaccine Research Center of the National Institute of Allergy and Infectious Diseases have identified and developed neutralizing monoclonal antibodies (nMAbs) against the MERS-CoV. This invention describes antibodies that target the Spike (S) glycoprotein on the coronavirus surface, which mediates viral entry into host cells.

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.

This technology is a set of influenza virus enrichment probes developed to increase the sensitivity of sequence-based, universal detection of all influenza viruses. This universal influenza enrichment probe set contains a unique set of 46,953 biotin-labeled, RNA probes, each 120 base-pairs long, that can be used to enrich for any influenza sequences without prior knowledge of type or subtype.

Scientists at the National Institute of Allergy and Infectious Diseases (NIAID) recently discovered a human neutralizing antibody, 10E8, that binds to the GP41 protein of HIV-1 and prevents infection by HIV-1. 10E8 potently neutralizes up to 98% of genetically diverse HIV-1 strains.

By engineering the 10E8 antibody, NIAID scientists have improved the properties of 10E8 that affect manufacturability, such as solubility, while preserving its neutralizing breadth and potency.

An effective human immunodeficiency virus type 1 (HIV-1) vaccine has long been sought to contend with the Acquired Immunodeficiency Syndrome (AIDS) pandemic.

One approach researchers have taken to elicit broadly neutralizing antibodies against HIV-1 is to stabilize the structurally flexible HIV-1 envelope (Env) trimer. Researchers stabilized the Env trimer in a conformation that displays predominantly broadly neutralizing epitopes and few non-neutralizing epitopes. Currently, BG505 DS-SOSIP is a leading vaccine candidate with the desired conformation and antigenicity.
