Abstract
In order to understand T cell function, it is necessary to completely decipher the molecular dynamics underlying T cell activation and effector function. In vitro easy-to-handle cellular models are valuable tools to study intracellular molecular mechanisms in live cells. The CD4 T cell line Jurkat (JK) has been widely employed to investigate intracellular signaling leading to T cell activation in response to T cell receptor (TCR) triggering. Here, we describe diverse, complementary protocols to evaluate the TCR- and costimulation-mediated T cell activation, as well as the immunological synapse assembly and cytokine production occurring as a consequence of successful early activation events. This in vitro model is extremely useful to address molecular mechanisms operating during T cell activation and effector function acting in diverse pathophysiological scenarios.
