Abstract: Disclosed is a method for detecting regulatory dendritic cells, the method comprising step a: detecting the presence or absence of one or more types of molecules on a cell surface in a cell population that comprises regulatory dendritic cells; and step b: identifying regulatory dendritic cells on the basis of the presence or absence of the one or more types of molecules. Also disclosed is a method for producing a cell population enriched for regulatory dendritic cells, the method comprising step 1: detecting the presence or absence of one or more types of molecules on a cell surface in a cell population that comprises regulatory dendritic cells; and step 2: obtaining a cell population enriched for regulatory dendritic cells on the basis of the presence or absence of the one or more types of molecules. Further disclosed is a cell population enriched for regulatory dendritic cells obtained by the method.

Abstract: Disclosed is a method for producing regulatory T cells, the method comprising: (1) differentiating cells that can differentiate into regulatory T cells, into which an expression construct is introduced, into regulatory T cells, the expression construct comprising: (a) conserved non-coding sequence (CNS) 1, CNS2, and CNS3 of Foxp3 gene; (b) a promoter; and (c) a nucleic acid encoding FOXP3. Also disclosed are regulatory T cells obtained by the method, and a pharmaceutical composition comprising the regulatory T cells.

Abstract: The present invention provides a therapeutic agent for an immune/inflammatory disease comprising an anti-human TIGIT antibody, which activates a suppressive immune checkpoint molecule (TIGIT), as an active ingredient. Also, provided is an antibody having the following characteristics a) and b):



a) the third CDR of heavy chain variable region comprises the amino acid sequence of SEQ ID NO: 4
b) the third CDR of light chain variable region comprises the amino acid sequence of SEQ ID NO: 6.
