The bacterial protein flagellin is the sole ligand of the innate immune receptor Toll-like receptor 5 (TLR5). Flagellins with strong agonism bind TLR5 at their D1 and D0 domains, while poor agonist si...

The cake is done and ready for tomorrow’s party! We won’t talk about the bit where I iced most of it before I realised it was backwards/upside down and was not a number 6 at all. Fixed with some cake surgery 😅

We can now assemble them beautifully in vitro, without the ugly defects you get using acid/base or denaturants.
This lets us put any synthetic cargo into these cages.
