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. https://t.co/BZdJHyctl2

Researchers in the Peng Lab use custom-built microscopy and nanotechnology to tag and follow the activity of individual proteins in real time.

@kyleconcannonMD @CellCellPress Thank you! Yes, we'd love to do that.

@GallowayLabMIT @broadinstitute @ChemistryMIT Thank you Katie!

[Sam Peng @CTSPeng]

Congrats to the whole team co-lead by Kaibo, Xiaojie, and João! @broadinstitute @ChemistryMIT in collaboration with Matthew Meyerson, Heidi Greulich, Michael Eck! Thanks to the Johnsson lab for help with SNAP/CLIP tags, and the editor/reviewers for a thoughtful review process.

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.

The 2026 Breakthrough Prize ceremony (“the Oscars for science”) celebrated the achievements of many remarkable scientists and their students and collaborators last weekend. Here’s the video of the show: https://t.co/eCHUnDqrYX. And here’s the segment in which Anne Hathaway and Alex Honnold (who climbed El Capitan free solo) presented the story of baby K.J.’s base editing treatment and introduced Kiran Musunuru, Rebecca Ahrens-Nicklas, Peter Marks, baby K.J. and his wonderful family, and myself: https://t.co/eCHUnDqrYX
