The present invention provides biomarkers allowing the diagnosis of symptomatic congenital cytomegalovirus (CMV) infection and in particular to differentiate between symptomatic and asymptomatic infected fetuses, methods of diagnosis of CMV using said biomarkers, diagnostic kits comprising thereof, and use of the kits and methods of diagnosing fetuses infected with a symptomatic congenital cytomegalovirus (CMV).

Disclosed are a monoclonal antibody that is specific to human cytomegalovirus and binds to human cytomegalovirus with a high affinity, or an antigen-binding fragment thereof, and a method for preparing the antibody. The antibody is also highly effective in neutralizing infections. Also disclosed are an epitope to which the antibody binds, and the use of the antibody in the diagnosis, prevention and treatment of an infected individual.

Monoclonal antibodies and antigen binding fragments that specifically bind to the Human Cytomegalovirus (HCMV) pentamer protein complex (gH/gL/UL128/UL130/UL131A) or other gH-containing complexes, and uses thereof.

Provided are methods of determining prognosis of a subject diagnosed with sepsis, by determining the baseline levels of T-cell senescence in the subject. Also provided are methods of treating a subject diagnosed with sepsis, by monitoring the subject diagnosed with sepsis and treating the subject which exhibits high baseline levels of T-cell senescence.

Disclosed herein are methods and devices for pathogen or antibody detection using unmodified signaling substances with or without unlabeled detection reagents. Unmodified signaling substance include, but are not limited to, a molecule, a material or a part of a material that is not modified with an antibody, an antigen, a pathogen, a DNA probe or an aptamer molecule. Unlabeled detection reagent refers to an antibody, an antigen, a pathogen, a DNA probe, or an aptamer that is not labeled with a signaling molecule such as enzyme, biotin, streptavidin, fluorescence or chemiluminescence probe, etc.

Disclosed herein are methods of selecting an allogeneic T cell line for therapeutic administration to a patient having or suspected of having a pathogen or cancer. Also disclosed are methods of selecting a donor from whom to derive an allogeneic T cell line for therapeutic administration to a patient having or suspected of having a pathogen or cancer.

The invention describes a method to identify and stage human herpesvirus-mediated neurodegenerations by measuring secreted herpesvirus protein and RNA levels in a blood sample and comparing that level to an individual's baseline or reference level. Combining herpesvirus secretome levels with other neurodegeneration biomarkers, such as coagulation factors and cell adhesion molecules, can aid in diagnosis and staging of neuropathology. Sensitive and economical ELISA diagnostic kits can detect and quantify the herpesvirus secretome and neurodegeneration biomarkers to diagnose herpesvirus-mediated neurodegeneration, stage disease, and predict disease progression. Finally, this method will elucidate herpesvirus-mediated neurodegenerations and aid in developing therapeutics.

The present invention relates to a method of detecting the presence of Cytomegalovirus and measuring antigenicity through detection and quantification of a pentameric complex by an indirect sandwich ELISA assay which ensures an appropriate concentration of this critical glycoprotein complex is present in the vaccine.

Provided herein are engineered T-cell receptors (TCRs) having nanomolar affinity for the immuno-dominant pp65 peptide residing between residues 495-503 (NLV) in complex with HLA-A2*02:01. The TCRs may be membrane-hound TCRs, soluble TCRs, chimeric TCRs, or chimeric antigen receptors. Also provided are methods of using the engineered TCRs to treat diseases, monitor disease progression, monitor vaccine efficacy, and detecting NLV/A2 presentation on the surface of cells.

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.
