New monoclonal antibody drug regrows lost teeth in ferrets

29-Mar-2021

Key points from article :

A specific gene regulates the behavior of molecules known to be key players in tooth development.

Begins with pair of molecules called bone morphogenetic protein (BMP) and Wnt.

"Suppressing USAG-1 benefits tooth growth," - Katsu Takahashi, lead author.

Tested the effects of several monoclonal antibodies on USAG-1 in mice.

Led to one antibody that disrupted the interactions between USAG-1 and BMP only.

BMP signaling played an essential role in determining the number of teeth the mice ended up with.

Delivering one-off dose of the antibody resulted in the generation of an entire tooth.

Follow-up experiments in ferrets produced similar results.

"Our next plan is to test the antibodies on other animals such as pigs and dogs," - Takahashi.

Treatment one day becoming an effect approach to tackling congenital tooth agenesis.
