    The study developed COORDINATE, an agent-based model to analyze T cell priming in lymph nodes considering spatial structure and competition.

  • 2

    Stromal architecture and trafficking biases significantly affect T cell encounters with antigen-bearing dendritic cells.

  • 3

    Competition for limited dendritic cell access can prevent many T cells from forming productive contacts, impacting activation.

  • 4

    Reduced T cell activation may result from limited access to antigen rather than solely from impaired T cell receptor signaling.

  • 5

    The findings suggest that enhancing early antigen access could be a strategy to improve adaptive immune responses.
