  • Publication number: 20230201263
    Abstract: An antigen-loaded nanogel is formed by loading or encapsulating one or more long peptide antigens or one or more protein antigens in a hydrophobized polysaccharide. The long peptide antigen(s) or protein antigen(s) contains (or each contain) one or more CD8+ cytotoxic T cell recognition epitopes and/or one or more CD4+ helper T cell recognition epitopes, which is/are derived from the antigen. The antigen-loaded nanogel is administered at least one day prior to administration of antigen-specific T cells to improve the efficacy of a T cell infusion therapy against an immune checkpoint inhibitor-resistant tumor. The hydrophobized polysaccharide may be pullulan having cholesteryl groups bound thereto. An immune-enhancing agent also may be administered in or with the antigen-loaded nanogel.

  • Publication number: 20220062398
    Abstract: A long-chain peptide antigen includes a plurality of epitopes. An interepitope sequence located between two of the plurality of epitopes contains four to ten consecutive tyrosines, threonines, alanines, histidines, glutamines, or asparagines. The killer T-cell recognition epitopes form complexes with MHC class I molecules and are recognized by CD8+ killer T-cells when the complexes are presented on the surfaces of antigen-presenting cells. The helper T-cell recognition epitopes form complexes with MHC class II molecules and are recognized by CD4+ helper T-cells when the complexes are presented on the surfaces of antigen-presenting cells. The peptide is cleaved within the first interepitope sequence upon uptake of the peptide into antigen-presenting cells. The long-chain peptide antigen may be administered to a patient together with a hydrophobized polysaccharide, such as cholesterol-modified pullulan, and/or an adjuvant, such as CpG oligo DNA.

  • Patent number: 10379565
    Abstract: An output driver circuit provides an overcurrent protection function by a simple circuit configuration. The output driver circuit has a constant-current circuit, a constant-current mirror MOS transistor, and a selector circuit. The constant-current mirror MOS transistor and the output MOS transistor constitute a current mirror circuit. The gate of the output MOS transistor is controlled by a voltage based on a constant current generated by the constant-current mirror MOS transistor, thereby limiting the current flowing between the source and the drain of the output MOS transistor.

  • Patent number: 9638761
    Abstract: To provide a magnetic sensor circuit that outputs a desired detection pulse while preventing an erroneous detection/erroneous release pulse output when a fluctuation in a power supply voltage occurs within an operating power supply voltage range. A magnetic sensor circuit is configured to include a detection circuit that detects a fluctuation in a power supply voltage or an internal power supply voltage and so as not to latch a determination output of a comparator by a latch circuit that, on the basis of a power supply fluctuation detection signal output from the detection circuit, holds the logic of a control clock signal output from an oscillation circuit for a prescribed period of time and determines the output logic of an output terminal.
