Excited to share our work on ErbB receptors published today @CellCellPress! Using multicolor, photostable UCNPs, we perform long-term (>15 min) single-particle tracking of EGFR, HER2, and HER3, enabling direct visualization of dimerization in live cells. cell.com/cell/fulltext/S0092…

Excited to share our work developing U-STORM super-resolution microscopy, now published @NatureNano! We engineered UCNPs that blink spontaneously and indefinitely, enabling two-color U-STORM imaging with sub-ångström localization precision using a simple optical setup without special imaging buffers. nature.com/articles/s41565-0…

ErbB family receptor dimerization dynamics and dysregulation via long-term single-molecule imaging

Ma et al. developed long-term single-particle tracking of ErbB family receptors in living cells using upconverting nanoparticles. They discovered constitutive HER2 and HER3 homodimerization and...

We also identified stable, ligand-independent heterodimers among all three receptors. These insights offer a comprehensive ErbB interaction network, elucidating diverse dimerization mechanisms and implications for oncogenic signaling.
