Abstract: The present invention relates to a cancer-specific tumor antigen neoepitope represented by any one of SEQ ID NOs: 1 to 214, an antigen-presenting cell loaded with the neoepitope, and a method for activating T cells for cancer treatment using the antigen-presenting cell. An antigen-presenting cell, that is, a dendritic cell, loaded with a cancer-specific tumor antigen epitope provided in the present invention enables rapid and effective induction of differentiation and proliferation of cancer antigen-specific T cells, preferably memory T cells, and the memory T cells thus activated can treat a cancerous or neoplastic condition or prevent recurrence, progression, or metastasis of cancer while avoiding the defense mechanism of cancer cells.
Abstract: Herein is reported a method for the co-cultivation of single deposited B-cells, which can be of any source, with EL-4 B5 feeder cells in a suitable co-cultivation medium. In the herein reported methods the EL-4 B5 cells have been irradiated with a dose of less than 40 Gy, preferably 9.5 Gy or less. Thereby the EL-4 B5 cells have a higher viability and maintain the ability to divide in cultivation at doses less than 6 Gy.
Abstract: Provided herein are methods and compositions for rapid, highly sensitive detection of SARS-CoV-2 in biological samples. In particular, provided herein is a rapid, low-cost method for detecting SARS-CoV-2 that provides reliable, visible test results and does not require PCR reagents, elaborate biosafety precautions, or sophisticated laboratory equipment.

Abstract: This invention relates to modified parvovirus inverted terminal repeats (ITRs) that do not functionally interact with wild-type large Rep proteins, synthetic Rep proteins that functionally interact with the modified ITRs, and methods of using the same for delivery of nucleic acids to a cell or a subject. The modifications provide a novel Rep-ITR interaction that limits vector mobilization, increasing the safety of viral vectors.
