T-cell activation is an essential event in the adaptive immune response to fight against infections. T cells were recently shown to be mechanosensitive, and to exert forces actively on the opposing antigen-presenting cell during activation. However, the molecular basis of force generation by T cells is poorly understood. Here, we report a molecular mechanism that involves the T-cell microtubule (MT) and actomyosin cytoskeletons, which interact through Rho GTPase activity. Our study highlights the role played by the MT cytoskeleton in regulating actomyosin-generated forces, which play a key role in T-cell activation.
