A T cell antigen receptor, an immune cell for expressing the T cell antigen receptor (TCR) and a preparation method and use thereof. The TCR disclosed in the present invention can be specifically activated by virus antigen peptide presenting cells, so that the release level of extracellular cytokines IFNγ and IL2 and the release amount of lactate dehydrogenase are improved, and target cells are significantly killed.

The present invention provides methods and immunoassays kits for the improved detection of cytomegalovirus (CMV) in a subject. In some embodiments, the methods and immunoassays kits differentiate between subjects who have developed a serological response to vaccination against CMV and subjects who have had a natural infection. In some embodiments, the methods and immunoassays kits differentiate between serological responses to different CMV serotypes.

Disclosed is an immunoassay method for detecting an analyte such as an antigen or an antibody in an isolated sample suspected to contain the analyte by incubating the sample with a plurality of binding partners, one of which carries a detectable label, wherein a label-specific binding partner is added that does not carry a label but binds to the detectable label. The method is applicable for a large variety of analytes and has proven particularly useful for analyte antibodies of the IgG and IgM class present in samples due to infections by pathogens. Also disclosed is a reagent kit useful for the method comprising at least two analyte-specific binding partners one of which carries a detectable label and a label-specific binding partner that binds to said detectable label but itself does not carry a detectable label.

Provided are devices for assessing the presence of SARS-CoV-2 in a biological sample, the devices comprising a substrate comprising a top surface and a back surface; and, an electrode on the top surface of the substrate, wherein the electrode is functionalized with a detection moiety that binds SARS-CoV-2 spike protein. Also disclosed are articles that include such devices, and methods for assessing the presence of SARS-CoV-2 in a biological sample using the disclosed devices. The present disclosure also provides devices for assessing the presence of herpes simplex virus (HSV) in a biological sample comprising a substrate that includes a top surface and a back surface; and, an electrode on the top surface of the substrate, wherein the electrode is functionalized with a detection moiety that binds HSV glycoprotein gD2, such as nectin-1. Also disclosed are articles that include such devices, and methods for assessing the presence of HSV in a biological sample using the disclosed devices.

Provided herein, inter alia, are compositions and methods for treating or preventing viral infections. The methods and compositions may modulate entry of a virus into a cell, viral fusion to a cell, or cell to cell spread of the virus by targeting one or more viral proteins or ligands thereof. The methods and compositions provided herein including embodiments thereof are contemplated to be especially effective for treating or preventing cytomegalovirus infections.

The present invention refers to a new monoclonal antibody or fragment thereof, called 11B2C7, which specifically recognizes herpes simplex virus (HSV), in its two types, herpes simplex virus type 1 and herpes simplex virus type 2 (HSV-1 and HSV-2). Preferably, the antibody of the invention is useful for the development of methods for the diagnosis of herpes simplex virus infection, as well as for the production of pharmaceutical compositions intended for the treatment, protection and/or prophylaxis of infection specifically caused by HSV-1 and HSV-2.

The present invention refers to a new monoclonal antibody or fragment thereof, called 14F5F6, which specifically recognizes herpes simplex virus (HSV), in its two types, herpes simplex virus type 1 and herpes simplex virus type 2 (HSV-1 and HSV-2). Preferably, the antibody of the invention is useful for the development of methods for the diagnosis of herpes simplex virus infection, as well as for the production of pharmaceutical compositions intended for the treatment, protection and/or prophylaxis of infection specifically caused by HSV-1 and HSV-2.

Protein and mRNA expression based methods for classification of gastric cancer, and methods of treatment based thereon.

The present invention relates to antigen binding protein, and in particular monoclonal antibodies, with bind to a HSV gEgI heterodimer, and to the use of such in detection and potency assays and in therapy.

The present disclosure provides antibodies that bind to a gD protein. The present disclosure also discloses a composition comprising an anti-gD protein antibody, a pharmaceutical composition comprising an anti-gD protein antibody and a pharmaceutically acceptable carrier. Also disclosed are a polynucleotide sequence encoding an anti-gD protein, a vector comprising such a polynucleotide, and a cell capable of expressing an anti-gD protein. The present disclosure also provides a method for producing an anti-gD protein antibody, a method for treating HSV-1 and/or HSV-2 infection, and a method for detecting HSV-1 and/or HSV-2.
