Disclosed herein are methods and composition useful for the detection of HPV in a subject sample.

The present disclosure relates to the treatment of HPV-associated cancers by small molecule PD-L1 inhibitors.

The present invention provides a fusion protein comprising an HPV cancer-causing protein segment, a coding sequence thereof and an application thereof in preparing drugs for detecting or treating HPV-related diseases. The fusion protein can simultaneously induce the humoral immunity and the cellular immunity for a high-risk HPV cancer protein and has anti-cancer activity in vivo.

A direct chemical lysis composition includes an assay compatible buffer composition and an assay compatible surfactant. When combined with a specimen storage composition, such compositions prevent undesired modifications to nucleic acid and proteins lysed from cells in the biological sample. Assays of samples from such compositions do not require expensive and time-consuming steps such as centrifugation and prolonged high temperature processing. The direct chemical lysis composition of the present invention permits direct nucleic acid extraction from the cells in the biological sample without the need to decant off the transport media or otherwise exchange the transport media with assay compatible buffers. There is no need to combine the sample with proteinase K or another enzyme to extract nucleic acids from the cells. A method for lysing cells to obtain target nucleic acid for assay and a kit for combining the direct chemical lysis composition with a sample are also contemplated.

Disclosed is a synthetic T cell receptor (TCR) having antigenic specificity for an HLA-A2-restricted epitope of human papillomavirus (HPV) 16 E7, E7.sub.11-19. Related polypeptides and proteins, as well as related nucleic acids, recombinant expression vectors, host cells, and populations of cells are also provided. Antibodies, or an antigen binding portion thereof, and pharmaceutical compositions relating to the TCRs of the invention are also provided. Also disclosed are methods of detecting the presence of a condition in a mammal and methods of treating or preventing a condition in a mammal, wherein the condition is cancer, HPV 16 infection, or HPV-positive premalignancy.

The invention relates to methods of assessing a patient's risk of developing Progressive multifocal leukoencephalopathy (PML).

The present invention provides an anti-HPV E7 protein monoclonal antibody and the use thereof. The antibody can detect the HPV16 E7 protein with high specificity and recognize the HPV18 E7 protein, thereby it can distinguish between the cancerous cervical epithelial cells and the cervical abnormal or non-cancerous cervical epithelial cells.

The invention relates to a microplate, an in vitro diagnostic kit for HPV type 16 E7 oncoprotein detection and a preparation method thereof The in vitro diagnostic kit is comprised of a microplate pre-coated with an HPV type 16 E7 antibody and an HRP-labeled HPV type 16 E7 antibody with concentration of 0.05-0.4 μg/ml, wherein the amount of the antibody in each microwell of the microplate is 0.05-0.5 μg. The in vitro diagnostic kit is used for directly detecting the expression of high-risk HPV-associated oncoprotein and the expression level, and thus has a clear judgment on the infection degree of high-risk HPV, and facilitates subsequent treatment.

The invention relates to a truncated L1 protein of the Human Papillomavirus Type 6, a virus-like particle consisting of the truncated L1 protein, a vaccine comprising said virus-like particle, and the use of the vaccine in the prevention of condyloma acuminatum or HPV infections.

Methods for producing a protein extract from cells, such as cells containing viral proteins, are provided. In general terms, the methods involve: increasing the pH of the cells to a pH of at least about pH 10.0 to produce an intermediate composition, and then, in the presence of a non-ionic detergent, neutralizing the pH of the intermediate composition to produce the protein extract. Kits and compositions for practicing the subject methods are also provided.
