The current invention provides nucleic acid sequences comprising the genomes of infectious hepatitis C viruses (HCV) of genotype 1a and 1b. It covers the use of these sequences, and polypeptides encoded by all or part of the sequences, in the development of vaccines and diagnostic assays for HCV and the development of screening assays for the identification of antiviral agents for HCV.

The ongoing COVID-19 pandemic, caused by severe respiratory syndrome coronavirus 2 (SARS-CoV-2), has created an immense public health, social, and economic burden. Variants of concern continue to emerge that have increased transmissibility, pathogenicity, or both and that reduce the effectiveness of current therapeutics and vaccines. Thus, there is a great need for broadly protective therapeutics.

Available for licensing through a Biological Materials License Agreement are the murine MAbs described in Beeler et al, "Neutralization epitopes of the F glycoprotein of respiratory syncytial virus: effect of mutation upon fusion function," J Virol. 1989 Jul;63(7):2941-2950 (PubMed abs). The MAbs that are available for licensing are the following: 1129, 1153, 1142, 1200, 1214, 1237, 1112, 1269, and 1243. One of these MAbs, 1129, is the basis for a humanized murine MAb (see U.S.

Interferons (IFNs) are a family of cytokines that function in response to an immune challenge such as a viral or bacterial infection. Type I IFNs are produced by immune cells (predominantly monocytes and dendritic cells) as well as fibroblasts and signal through a specific cell surface receptor complex (IFNAR) that consist of IFNAR1 and IFNAR2 chains. Type-I IFNs exert several common effects including antiviral, antiproliferative, and immunomodulatory activities. However, Type I IFNs also have pro-inflammatory effects, especially in the presence of TNF-a.

When a coronavirus was identified as the causative agent of the COVID-19 pandemic, researchers at the Vaccine Research Center of the National Institute of Allergy and Infectious Diseases (NIAID), together with their collaborators at the University of Texas at Austin and Dartmouth College, responded quickly to engineer the SARS-CoV-2 spike (S) protein for use in vaccines against SARS-CoV-2.

The technology encompasses antibodies and methods that may overcome the shortcomings of commercial checkpoint inhibitors (CPIs). Scientists at NIAID have identified MHC-I specific antibodies that selectively inhibit interactions with inhibitory leukocyte immunoglobin-like receptors (LILRs) but not T-cell receptors. Administration of the antibodies increased proliferation and activation of both innate and adaptive immune system cells, and lead to anti-tumor and anti-viral activity in an array of relevant mouse models of disease.

This technology includes three new compound classes displaying either differential or comprehensive antimalarial activity across geographically diverse lines. These compounds were identified from a quantitative high throughput screen of a novel chemical library with unique chemical complexity and are potential candidates for treating malaria.

NIAID, IAVI, Emergent, and Scripps have developed two recombinant adenovirus type 4 (Ad4) vector-based vaccine candidates. These replicating Ad4 vector-based candidates have shown improved activity against tier 2 HIV-1 isolates in experimental animals. Tier 2 isolates are among the most prevalent in infected populations. The two candidates, Ad4-Env150KN and Ad4-Env145NFL, incorporate novel design features based on Ad4-EnvC150 (1086c). Specifically, the truncation of the cytoplasmic tail of Env increases cell surface expression and has resulted in improved antigenicity from both candidates.

The technology relates to the identification and validation of eight biomarkers for active central nervous system (CNS) intrathecal inflammation. The management of neuroimmunological diseases is severely hindered by an inability to reliably measure intrathecal inflammation. Current laboratory tests, that were developed over 40 years ago, do not capture low to moderate levels of CNS inflammation and provide limited information about its phenotype.

This technology includes microRNAs for use in cell lines for protein production and potentially future treatments of cancer or diseases related to metabolism. Mmu-miR-466h was identified as a major apoptotic regulator in suspension adapted Chinese Hamster Ovary cells. Mmu-miR-466h was found to have the pro-apoptotic activity by targeting some anti-apoptotic genes for degradation during the exposure of CHO-S cells to the nutrients depleted media.
