Contribution

The paper introduces a simplified membrane model that reproduces observed receptor patterning and applies a functional RG analysis for deeper insights.

Findings

Model reproduces experimentally observed receptor patterns

RG analysis reveals scale-dependent behavior of the synapse

Provides a theoretical framework for understanding T cell recognition

Abstract

The immunological synapse is a patterned collection of different types of receptors and ligands that forms in the intercellular junction between T Cells and antigen presenting cells (APCs) during recognition. The synapse is implicated in information transfer between cells, and is characterized by different spatial patterns of receptors at different stages in the life cycle of T cells. We obtain a minimalist model that captures this experimentally observed phenomenology. A functional RG analysis provides further insights.
