Q: Question: Is integrin -8 , but not -5 or -6 , protein expression increased in livers of children with biliary atresia?
Answer: Our data show that integrin 8, but not integrin 5 or integrin 6, protein expression is increased in liver specimens of patients with BA. These data support the mounting evidence that transforming growth factor- (TGF-) activation is responsible for the fibrosis found in BA. Anti-integrin 8 or more global integrin blocking strategies may be therapeutic options in BA, but further work is clearly needed.
A:
yes
