Human-Bovine Reassortant Rotavirus Vaccine

Rotavirus is a major cause of severe diarrhea and dehydration in infants and young children. Vaccines that cover the most important rotavirus serotypes could help reduce serious illness worldwide.

Researchers at NIAID’s Laboratory of Infectious Diseases developed a multivalent human-bovine reassortant rotavirus vaccine using vaccine strains created by combining selected genes from human and bovine (cow) rotaviruses. This approach targets the most important rotavirus serotypes at once, including G1, G2, G3, and G4, with the potential to expand coverage to G5, G9, and G10.

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.

Codon-optimization of HIV-1 Viral Infectivity Factor (VIF) Gene

Expression of the HIV-1 Vif protein in the absence of other viral factors such a Tat and Rev is extremely inefficient due to the presence of inhibitory sequences on its mRNA. This invention uses codon optimization to remove such inhibitory sequences without altering the amino acid sequence of the protein. The modified vif gene in the resulting pcDNA -hVIF vector is expressed under the control of the CMV promoter. In this, the protein functions as wild type and is more amendable to high-level expression in mammalian cells.

Characterization of novel pan anti-HLA antibodies that block LILR inhibitory receptors and activate anti-tumor immunity

       Cancer immunotherapy has transformed treatment for some patients, but many tumors still do not respond well to current options, including checkpoint inhibitors. Researchers at NIAID’s Laboratory of Immune System Biology (LISB) have developed new antibodies designed to help the immune system fight tumors. These lab-made antibodies, called pan-anti-HLA monoclonal antibodies, block signals that can limit immune cell activity.

Clinical Advancements in Intracellular Pathogen Infection Treatment through CD47 Blockade for Augmented Phagocytic Clearance

The technology described involves a groundbreaking method for treating intracellular pathogen infections by targeting CD47, a widely expressed transmembrane glycoprotein that acts as a ligand for phagocytic receptors. By administering agents that inhibit CD47 binding to these receptors, the approach enhances the phagocytic removal of infected cells, leading to increased clearance of intracellular pathogens.

Advancements in Coronavirus Vaccine Development: Innovative Engineered RBD Antigens Redefining the Landscape

Advancing Anthrax Detection with Monoclonal Antibodies Against Bacillus anthracis Protective Antigen

This technology involves the creation of monoclonal antibodies through hybridoma technology, specifically, hybridomas 3B6, 14B7, 2D3, 2G4, 1G3, 6H3, 6C5, and 3D12, which exhibit a high degree of reactivity with Bacillus anthracis protective antigen (PA). These monoclonal antibodies have shown great promise in the field of anthrax detection and diagnosis. Their exceptional specificity for Bacillus anthracis PA suggests their potential application in diagnostic devices.

Extended Serum Half-Life in Therapeutic Antibodies: Advancements with Enhanced lgG1 Fe Variants

This technology involves the development of lgG1 Fe variants designed to interact more effectively with the neonatal Fc receptor (FcRn) in a pH-dependent manner. By enhancing this interaction, these variants extend the serum half-life of therapeutic antibodies, reducing the need for frequent administration. This breakthrough holds the potential to make therapeutic antibody treatments more convenient, cost-effective, and accessible for a wide range of diseases.

Monoclonal Antibodies in the Advancement of Bacillus anthracis Diagnosis and Surveillance

Monoclonal antibodies produced by hybridomas IE5, IE9, and 13B3 are specific for the Bacillus anthracis PA20 fragment. These antibodies hold significant potential for rapid and precise Bacillus anthracis diagnosis in clinical and environmental samples. They can be employed in various diagnostic assays, offering a valuable tool for public health and biosecurity applications. Rigorous testing and validation are essential before their integration into diagnostic devices.
