“…However, recent evidence shows that these inflammatory responses to Ti particles are based on the adherent endotoxin to Ti particles (Bi et al , 2001) and that Ti ions inhibit osteoclast formation induced by PGE 2 . In an in vitro study Matsunaga et al (2001) questioned whether Ti particles are directly involved in osteolysis caused by wear debris. In the present study, we found, rather unexpectedly, that Ti particles with no adherent endotoxin inhibited osteoclastogenesis without affecting osteoclastic bone resorbing activity.…”

“…FAK ainda participa da fosforilação de tensina e paxilina, proteínas estruturais dos contatos focais (JULIANO, 1996) (POSTIGLIONE et al, 2003). Recentemente, foi evidenciado que íons de titânio causam uma degradação preferencial maior de osteoclastos do que osteoblastos, quase como um mecanismo apoptótico (MATSUNAGA et al, 2001) 3 PROPOSIÇÃO O presente projeto de pesquisa tem a proposição de avaliar qualitativamente a expressão das integrinas por meio do cultivo celular sobre a superfície de implantes de titânio.…”
