Nanopores can activate human T cells without biochemical signals

AI Summary

Researchers from multiple European institutions have discovered that human immune cells can be activated by the surface structure of materials without biochemical signals. This finding may have important implications for medical treatments involving immune cell activation.

Immune cells protect and heal the human body. In medicine, they are specifically activated through biochemical reactions to treat certain diseases. Researchers at the Helmholtz-Zentrum Hereon, ETH Zurich, Humboldt University of Berlin, Charité Berlin and Inselspital Bern have now discovered that immune cells also respond to the surface structure of materials—without chemistry.
