摘要:
The present disclosure provides an artificial adjuvant vector cell inducing an immune response to a spike protein of a coronavirus, a pharmaceutical composition containing the cell, and use of the cell and the composition. According to the present disclosure, the cell can be an artificial adjuvant vector cell (aAVC) expressing a spike protein of a coronavirus.
摘要:
The present invention provides use of KLRG1 as a marker specific to memory invariant NKT cells. Using an antibody that specifically recognizes KLRG1, memory invariant NKT cells can be easily detected or isolated.
摘要:
The present invention provides a production method of a functional differentiated cell having a post-rearrangement genotype of a particular antigen receptor gene, which includes culturing a stem cell having the genotype in a medium to give the differentiated cell derived from the stem cell. As the stem cell having the genotype, a stem cell (e.g., ES cell) established by transplantation of the nucleus of a cell having the genotype is preferable. As the differentiated cell, NKT cell is preferable.
摘要:
Provided is a method of evaluating the antigen presentation potential of human dendritic cells, including the following steps: (1) a step for administering α-galactosylceramide-pulsed human dendritic cells to a non-human mammal; (2) a step for collecting a sample containing NKT cells from the non-human mammal; (3) a step for detecting the activation of NKT cells present in the sample. Further provided is an agent for human NKT cell immunotherapy, containing human dendritic cells that have been assessed by the method as those possessing an antigen presentation potential for NKT cells.
摘要:
A modified immunocyte: (1) which expresses an exogenous unmodified T cell receptor α-chain and an exogenous T cell receptor β-chain on the cell surface thereof; or (2) which contains a polynucleotide encoding a T cell receptor α-chain and a polynucleotide encoding a T cell receptor β-chain. Thus, a new tool whereby immunity can be appropriately induced in vivo is provided.
摘要:
The present invention provides a means to be used for a new immunotherapy of cancer or infection utilizing activation of dendritic cell (DC) by innate immunity, namely, a method of preparing a cell co-expressing a target antigen and CD1d and having an ability to activate immunity against the target antigen, comprising the following steps (a) and (b): (a) a step of transfecting an mRNA encoding the target antigen into a CD1d-expressing cell to give a cell co-expressing the target antigen and CDld; and (b) a step of treating the cell obtained in step (a) with a CD1d ligand in a culture medium.
摘要:
This disclosure relates to a peptide inducing immunity to SARS-CoV-2. Also, the disclosure relates to a composition containing the peptide and inducing immunity to SARS-CoV-2.
摘要:
A cell of the present invention contains a nucleic acid construct encoding a WT1 gene product or a fragment of the WT1 gene product. The nucleic acid construct contains (i) a region encoding a desired fragment of the WT1 gene product and (ii) only AUG as a functional start codon. The present invention can provide a cell into which the nucleic acid construct is introduced so that an expression level of a WT1 gene product or a fragment of the WT1 gene product is remarkably enhanced.
