Abstract: The present invention provides a novel immunity induction method, particularly, a method of simultaneously inducing activation of NKT cells and T-cell immune responses. To be more precise, the present invention provides a target antigen and CD1d co-expressing cell, and a preparation and identification method thereof; a target antigen and CD1d co-expressing cell capable of activating immunity to the target antigen, and a preparation method thereof; an immunoinducer to a target antigen or a pharmaceutical agent, which contains a target antigen and CD1d co-expressing cell capable of activating immunity to the target antigen; a target antigen and CD1d co-expressing vector; a kit containing an expression vector and/or a CD1d ligand; and the like.

Abstract: The present invention provides a superior method of functional analysis of NKT cells, which enables function analysis of low frequency NKT cells, is independent of the function of autologous APCs, and can avoid an influence of secondary factors and the like.

Abstract: The present invention relates to a fermented food and process for producing the same, in which the food contains a sufficient amount of conjugated fatty acid and is excellent in digestivity and absorbability, physiological effects, safety, sensory properties, and the like. The fermented food is obtained by adding a conjugated fatty acid in the form of a glyceride to a fermentation medium either before or after the fermentation by the fermenting bacterium, and the final fermented food product contains such conjugated fatty acid in the form of a glyceride. The conjugated fatty acid of the glyceride type is a glyceride derivative containing a fatty acid having conjugated double bonds (a conjugated fatty acid) as its constituent fatty acid, and sustains many of useful physiological activities of the conjugated fatty acid while coping with the inhibitory action of free fatty acids to the fermenting bacterium.
