Mechanical tuning of synaptic patterns enhances immune discriminations

Milos Knezevic

Abstract: An immunological synapse is an adhesive intercellular junction, patterned with a variety of receptors and ligands, that forms between B cells and antigen-presenting cells (APCs) during recognition. Via synapses, B cells use mechanical pulling forces to extract recognized antigen (Ag) from APCs. Depending on its stage of development, a B cell exhibits distinct synaptic patterns and uses force at different strength and timing, which appears to lead to varied stringency of Ag affinity discrimination. We use a statistical-mechanical model to study how the experimentally observed synaptic architectures can originate from normal cytoskeletal forces coupled to lateral organization of mobile receptors, and show how this active regulation scheme, collective in nature, may enhance the efficiency and capacity of discrimination.
