Suemasa Daichi
Abrégé
This protein collection determination system comprises: a first determination unit that uses first image data obtained by capturing a time series of images of a culture of a cell population infected with a virus as first input data and determines, as first output data, whether a cell population infected with a virus is in a suitable state for collecting a protein; and an acquisition unit that acquires image data obtained by capturing a time series of images of the inside of a culture container. The first determination unit performs determination by means of a first model, and the first model is a trained model obtained by performing deep learning of a first neural network using the actual values of the first input data and the actual values of the first output data as first teacher data.

Hence, prostate cancer cell lines (LNCaP-CR cells and LNCaP cells) were compared by SST-REX, and CXADR was identified as a molecule involved in tumor formation and so on. Then, a monoclonal antibody against CXADR was prepared, and the anti-cancer activity, ADCC activity, CDC activity, and so forth were examined. The result revealed that an antibody capable of binding to an epitope present at positions 181 to 230 of a CXADR protein derived from human exhibited an anti-cancer activity against prostate cancer cells, pancreatic cancer cells, and colorectal cancer cells. Further, it was also revealed that the antibody had an ADCC activity and a CDC activity. Moreover, the structures of light chain and heavy chain variable regions of the antibody were successfully determined.

From PBMCs originating from an H1N1pdm patient, the inventors acquired three types of human monoclonal antibodies which bind to epitopes present at positions 40-58 of the HA2 region of an H1N1pdm-derived hemagglutinin protein. The inventors also discovered that these antibodies have neutralizing activity with respect to the H1 subtype and the H5 subtype of group 1 influenza A virus. The inventors also discovered that the three types of antibodies have neither affinity nor neutralizing activity with respect to the H2 subtype, which belongs to group 1 but has the amino acid at position 45 substituted with phenylalanine and the amino acid at position 47 substituted with glycine in the H1N1pdm-derived HA2 region.

It is intended to provide a closed culture system of virus-specific CTL which has convenience and safety features and can be implemented at low cost for the purpose of achieving the practical application of cell therapy with the use of CTL specific to a virus (particularly HCMV). After virus-specific CTL epitope peptide and peripheral blood mononuclear cells are mixed and incubated, restimulation with this epitope peptide is given in a medium. Then, virus-specific CTL is isolated by targeting freshly expressed CD137 antigen, and T cells proliferated from peripheral blood mononuclear cells by the stimulation with OKT3 (anti-CD3 monoclonal antibody) are brought into contact with the epitope peptide in the medium. Then, the T cells and the virus-specific CTL are cocultured, whereby the virus-specific CTL is proliferated.

Abrégé
[PROBLEMS] To provide a method of constructing a recombinant proteoliposome that is suitable for diagnosis, a plate for detection coated with the recombinant proteoliposome, a kit for detection and so on. [MEANS FOR SOLVING PROBLEMS] A recombinant proteoliposome, in which a budding virus particle of a recombinant baculovirus expressing on the envelope a target membrane receptor (for example, human thyroid stimulation hormone receptor, an acetylcholine receptor, an insulin receptor, a β1-adrenaline receptor, an asialoglycoprotein receptor, etc. each participating in an autoantibody-related disease) is fused with a liposome is prepared. Compared with the recombinant baculovirus, this proteoliposome has an improved ability to bind to an autoantibody, which makes it possible to easily produce a kit to be used in detection.
