摘要:
Cell-based immunotherapy (e.g., immunization or vaccination) may be improved by frequent administration to a human subject of allogeneic cancer cells secreting a modified heat shock protein (e.g., gp96), depletion of B cells in the subject, or both. Antigen (e.g., epitope derived from neoantigen or tumor antigen of allogeneic or syngeneic cancer cells) may induce a specific immune response in the subject. For example, the epitope bound in an immunogenic complex with the secreted heat shock protein may be obtained from allogeneic cancer cells coexpressing both secreted gp96 and antigen, or from syngeneic cancer cells of the subject expressing only antigen.

摘要:
The present invention relates to methods for purifying immunogenic, prophylactically and therapeutically effective complexes of modified heat shock proteins noncovalently associated with antigenic peptides of cancer or infected cells. The claimed methods comprise the constructing of a nucleotide sequence encoding a secretable modified heat shock protein, expressing the sequence in an appropriate host cell, recovering the immunogenic complexes from the cell culture and the cells, and purifying the immunogenic complexes by affinity chromatography. Large amounts of such immunogenic complexes can be obtained by large-scale culturing of host cells containing the genetic sequence. The complexes can be used as a vaccine to elicit specific immune responses against cancer or infected cells, and to treat or prevent cancer or infectious diseases.

A developing device includes a developer bearer and a stirring conveyor. The stirring conveyor includes a first conveying chamber including a conveying member and a second conveying chamber to receive the developer from an end of the first conveying chamber. The conveying member includes a forward winding blade, a reverse winding blade, and a shaft portion on which the forward winding blade and the reverse winding blade are mounted with a space therebetween. A circumferential phase of the conveying member at a start position of the reverse winding blade is different from a circumferential phase of the conveying member at an end position of the forward winding blade. The conveying member is disposed in the first conveying chamber so that the space is opposite a portion at which the second conveying chamber receives the developer from the end of the first conveying chamber.
摘要:
A developing device includes a developer bearer, a developer regulator disposed opposite the developer bearer across a first gap, and an opposing member having an opposing face disposed opposing the developer bearer across a second gap wider than the first gap. The opposing face is disposed adjacent to and upstream from the developer regulator in a direction of rotation of the developer bearer. The opposing face is inclined relative to an orthogonal plane direction orthogonal to a side face of the developer regulator. The opposing face is inclined to progressively reduce a distance from the developer bearer to the opposing face in a direction of rotation of the developer bearer. A difference between the second gap and the first gap is not greater than 1.75 times as large as the first gap.

摘要:
A development device includes a developer bearer to carry the developer to a development range, a magnetic field generator disposed inside the developer bearer for generating magnetic force, a developer regulator for adjusting an amount of the developer, a developer supply compartment disposed adjacent to the developer bearer, separated by a side wall from a portion where the developer bearer is provided, a developer agitator provided in the supply compartment, and a blocker disposed above the side wall of the supply compartment across a supply gap through which the developer moves from the supply compartment. The magnetic field generator has an attraction magnetic pole and a regulation magnetic pole. The blocker prevents the developer blocked by the developer regulator from moving along a magnetic force line of the regulation magnetic force toward the circumferential surface of the developer bearer.
