摘要:
The present inventors worked on elucidating the mechanism of antigen cross-presentation by dendritic cells, and revealed that foreign antigens taken up in dendritic cells are degraded by proteasomes after undergoing polyubiquitination. Based on the novel finding that polyubiquitination is involved in cross-presentation, the promotion of polyubiquitination was attempted by a number of methods, and the promotion of antigen presentation was confirmed. These methods enable the production of dendritic cells effective for inducing CTL activation.
摘要:
The present inventors worked on elucidating the mechanism of antigen cross-presentation by dendritic cells, and revealed that foreign antigens taken up in dendritic cells are degraded by proteasomes after undergoing polyubiquitination. They discovered a positive correlation between the uptake amount of an antigenic protein by dendritic cells or the level of polyubiquitination and the level of antigen presentation of the antigenic protein. Based on these findings, methods were developed for predicting the intensity of cross-presentation of an anti genic protein by measuring the amount of antigenic protein taken up or polyubiquitinated protein. The use of these methods allows selecting antigenic proteins that are readily presented as antigens from among a number of proteins. The methods of the present invention enable suitable cancer immune vaccines to be provided through selection of more suitable cancer-specific proteins.
摘要:
An objective of the present invention is to provide methods for selecting candidate peptides presented on the surface of cancer cells following binding to MHC class I molecules, wherein the peptides are involved in the stimulation of T cell immunity (cellular immunity). The present inventors discovered a new principle of MHC I-mediated antigen presentation in which a T cell antigen epitope is more efficiently presented on MHC I molecules when it is positioned at the N-terminal side than when positioned at the C-terminal side.

摘要:
A molding condition optimizing system for an injection molding machine comprising plastic flow condition optimizing section and an operating condition determining section is disclosed. The plastic flow condition optimizing section carries out a plastic flow analysis on a molded part model, and determines an optimum flow condition in a filling stage and a packing stage of an injection molding process of the injection molding machine by repeatedly executing an automated calculation using the result of the plastic flow analysis and the plastic flow analysis itself. The operating condition determining section comprises an injection-side condition determining section for determining an optimum injection-side condition of the injection molding machine according to the optimum flow condition obtained by the plastic flow condition optimizing means and a knowledge database with respect to an injection condition, and a clamping-side condition determining section for determining an optimum clamping-side condition according to the molded part form data generated by the plastic flow condition optimizing means, the result of the plastic flow analysis, mold design data, and a knowledge database with respect to a mold clamping condition.
