On-Demand Webinar: Evaluation of Checkpoint Inhibitor Therapies using a Mixed Lymphocyte Reaction (MLR) Assay


Immune checkpoints are signaling molecules which control the synapse between T cells and antigen presenting cells (APCs).

Checkpoint inhibitor therapies target and inhibit the signals that ‘switch off’ T cells, leading to an upregulation of T cell activation and tumor cell killing.

The mixed lymphocyte reaction (MLR) mimics the T cell and APC synapse by co-culturing immune cells from two individuals. MLR is used as a model, to explore the effects of checkpoint inhibitor drugs in vitro; facilitating biological research applications and drug discovery processes.
