Mineral trioxide aggregate (MTA) has been introduced as a choice material for regenerative dentistry. To date, the diverse biological activities of MTA, including its anti-inflammatory effects, have been extensively discussed. However, there is limited insight into the link between MTA and immune cell migration. In this study, we report the role of MTA in enhancing both chemotactic and chemokinetic immune cell migration through distinct signaling pathways. By using versatile live imaging techniques, we demonstrated that MTA-mediated CaSR activation induced diverse downstream pathways to govern cell migratory capacity. In this context, Cdc42 generates cytoskeleton-driven cellular protrusions to steer directional cell migration (chemotaxis) whereas Ca2+-calmodulin dependent myosin light chain kinase induces cell contractility that plays an important role in speeding up the average migration speed (chemokinesis). Our findings illuminate an unrecognized role for MTA and the related CaSR signaling network in immune cell migration, providing evidence that can drive development of novel approaches to immunological therapy.
