Flagellin works through TLR5 as a potential vaccine adjuvant

Flagellin is a potent activator of many cell types.

Flagellin has the following properties

- adjuvant
- promoter of cytokine production
- trigger of a recruitment of T and B lymphocytes
- activates TLR5(+)CD11c(+) cells and T lymphocytes

The plasticity of flagellin has allowed for the generation of flagellin-Ag fusion proteins that are effective vaccines in animal models. The adjuvant effect of flagellin brings a lot of human research interest.
