Nanobody mimicry of a GPCR recognition site disrupts human C5a-C5aR1 signaling
Key Takeaways
  • Nanobodies are shown to bind human and mouse C5a with high affinity.
  • In cell assays these nanobodies were reported to block receptor activation.
  • Structural work showed the nanobody mimics a C5aR1 extracellular turn.
