The invention provides a method for rapid, highly specific and sensitive detection and quantification of a virus by observing viral substrate binding to its host receptor protein. The invention also provides a method for rapid, highly specific and sensitive detection and quantification of a virus in an individual suspected of being infected with a virus. The invention further provides a test kit for rapid, highly specific and sensitive point-of-care detection of a virus in an individual. The viruses and their host receptor proteins that can rapidly be detected include SARS-CoV-2 and its host receptor protein ACE2. The surprisingly rapid, specific and sensitive method of the invention provides a point-of care test capable of diagnosing individuals suffering from COVID-19 by observation of a color change in the assay, which color change occurs in about five minutes, and which test can be completed by a user in about one hour.

The present invention provides matched antibody pairs for the specific detection of one or more of the four dengue virus serotypes in a biological sample that may contain one or more of such dengue virus serotypes. Each matched antibody pair is capable of detecting not more than one serotype of dengue virus NS1 protein that may be present in the sample and will not cross react with other serotypes that may be present in the sample. Multiple matched pairs may be used to detect one or more dengue virus serotypes that may be present in a sample. Such matched pair antibodies, facilitate the development of confirmatory in vitro diagnostic tests such as sandwich immunoassays, that detect and distinguish the presence of one or more dengue virus serotypes in a biological sample, preferably a sample derived from human subject. The invention also provides kits comprising the matched antibody pairs of the invention and methods for using the kits for immunoassays for the specific detection of one or more serotypes of dengue virus in a patient population. The present invention also provides monoclonal antibodies specific for the NS1 protein of dengue virus and therapeutic compositions and methods for treating dengue virus infection.

An object of the present invention is to provide a technique for preventing or treating HTLV-1-associated diseases, such as ATL, a material for use in the technique, a method for screening the material, and the like. The present invention provides a TCR screening method comprising sorting HTLV-1-derived antigen-recognizing cells from cells derived from an HTVL-1 patient and subjecting the HTLV-1-derived antigen-recognizing cells to TCR repertoire analysis, ranking the TCR types in descending order of the number of cells of each TCR type, and selecting a highly ranked TCR. The present invention provides a prophylactic or therapeutic agent for an HTLV-1-associated disease, the agent comprising a TCR comprising specific CDRs that can be obtained by the TCR screening method and cells expressing the TCR.

Certain embodiments are directed generally to compositions and methods related to recombinant vesicular stomatitis virus vectors (GrVSV) encoding Crimean-Congo Hemorrhagic Fever glycoprotein precursor (CCHFV-GPC) and forming a recombinant vesicular stomatitis virus vector encoding Crimean-Congo Hemorrhagic Fever glycoprotein precursor (GrVSV-CCHFV-GPC).

A lab-on-skin biosensor for detecting target molecule and vital sign monitoring, a method of manufacturing, and a method of using the same, wherein the lab-on-skin biosensor is fabricated with a microfluidics layer, a moisture resistant layer, a multimodal sensing layer comprising an electrode, and a logic circuit that may include a processor and non-transitory memory with computer executable instructions embedded thereon.

A recombinant polypeptide can be used in the diagnosis of the presence of a Zika virus in a patient. The recombinant polypeptide includes SEQ ID NO1 or a variant thereof, where the recombinant polypeptide is a monomer, a dimer, or a hexamer.

The present invention discloses a new approach to produce membrane or lipid bilayer mimicking surfaces, their use in the aforementioned areas of application, a kit of parts and a sensor.

The present disclosure relates to solid dosage forms comprising anti-HCV compounds and methods of using such dosage forms to treat or prevent HCV infection. Direct-acting antiviral agents (DAAs) have a high cure rate, and favorable tolerability in persons infected with hepatitis C virus (HCV). However, shorter courses of therapy can improve adherence, affordability, and increase DAAs accessibility. The addition of an NS3 protease inhibitor to dual NS5A-NS5B (nucleoside) inhibitors enhances antiviral efficacy, and reduces treatment duration to 3 weeks (wks) in individuals with a rapid virologic response (RVR), defined as plasma HCV RNA<500, or <1,000, IU/mL by Day 2 of treatment.

The subject invention pertains to isolated influenza virus that is capable of infecting canids and causing respiratory disease in the canid. The subject invention also pertains to compositions and methods for inducing an immune response against an influenza virus of the present invention. The subject invention also pertains to compositions and methods for identifying a virus of the invention and diagnosing infection of an animal with a virus of the invention.

This invention provides immunogenic compositions comprising an immune stimulant and an respiratory syncytial virus (RSV) oligopeptide or an unglycosylated RSV polypeptide. The RSV oligopeptides are shown in SEQ ID NO: 3-33. The unglycosylated RSV polypeptide may consist essentially of the ectodomain of an RSV G protein, such as that shown in SEQ ID NO: 2 or the ectodomain of an RSV F protein such as the ectodomain of the F protein shown in SEQ ID NO: 39.
