CD2 is preferentially enriched at microvilli tips on OT-I T cells, where it strongly associates with TCR and persists at the immunological synapse after 1–2 h of stimulation.
- Why it matters: Microvilli are key signaling hubs during antigen scanning, but their nanoscale 3D organization in the immunological synapse is difficult to measure, limiting understanding of how adhesion and TCR signaling are spatially coordinated.
- What they did: Using NanoMAP, an expansion microscopy-based platform, the authors mapped CD2, LFA-1, and TCR on OT-I T cells at 35–60 nm resolution, including before and after 1–2 h of antigen stimulation.
- The result: After antigen engagement, TCR patches are selectively lost from microvilli, while CD2 and LFA-1 are retained, implying receptor-specific microvillar remodeling that NanoMAP can quantify.
