Which research group led the study on tissue-resident memory CD4⁺ T cells?

The study was led by a research group from the Graduate School of Medicine, Chiba University, including Chiaki Iwamura and Kiyoshi Hirahara.

What cell surface molecule controls the retention of CD4⁺ TRM cells in organs?

The mechanism by which these cells remain in organs is controlled by a cell surface molecule called CD69.

In which scientific journal and on what date was this research finding published?

The research finding was published in the international scientific journal Science Advances on April 8, 2026.

What property do CD4⁺ TRM cells acquire in inflamed tissues and retain in the blood?

They acquire an inflammation-prone property within inflamed tissue and retain it even after migrating into the bloodstream.

What model and specimens were analyzed by the researchers in this scientific study?

The researchers analyzed the cells using asthma model mice and human patient specimens in this study.
