| Outline of Final Research Achievements |
Invariant (i)NKT cells recognize a complex of the antigen-presenting MHC-like molecule CD1d and a glycolipid and play a key role at the initial immunological defense in infection and cancer. After the activation, the fate of iNKT cells toward memory has not been identified. Here we show the presence of effector memory-like KLRG1+iNKT cells in the lung. They express the distinct expression of adhesion molecules, chemokine receptors and NK receptors and can produce high amount of IFN-gamma. In addition, we identified the specific molecules, of KLRG1+ iNKT cells by RNA-seq analysis.
