T Cells Use Tissue Stiffness to Help Shape Immune Memory
Immune cells do more than recognize pathogens and respond to chemical signals. A McGill University study found that T cells can also sense the physical properties of their surroundings, particularly how stiff the surrounding tissue is.
Researchers observed that these mechanical signals help guide whether activated T cells develop into long-lasting memory cells. Because memory T cells protect against future infections, the result suggests that tissue stiffness may play a role in shaping the strength and persistence of immune protection.
The discovery expands the traditional view of immune-cell behavior and points to a possible connection between tissue mechanics and long-term immunity. The article does not specify the mechanism in greater detail or indicate whether the finding is ready for clinical application.
