| Research Abstract |
When T cells recognize antigen on antigen.presenting cells, they start adhere and generate T cell antigen receptors (TCR) microclusters (TCR-MCs) which is a unit for starting T cell activation. The TCR-MCs move toward the center of the interface and form immunological synapse. We revealed and published that the transportation of TCR-MCs depends on microtubule motor, dynein and negatively regulate T cell activation. These observation were based on the quantitative analysis of TCR-MCs generated under physiological stimulus conditions.
