Mechanosensing in T lymphocyte activation.

Journal article

Mechanical forces play an increasingly recognized role in modulating cell function. This report demonstrates mechanosensing by T cells, using polyacrylamide gels presenting ligands to CD3 and CD28. Naive CD4 T cells exhibited stronger activation, as measured by attachment and secretion of IL-2, with increasing substrate elastic modulus over the range of 10-200 kPa. By presenting these ligands on different surfaces, this report further demonstrates that mechanosensing is more strongly associat...
