ABSTRACT
We review the growth factor receptor-mediated cell signaling events that induce the responses required for the maintenance of corneal epithelial health. Our focus is to show how such responses contribute to sustaining corneal transparency and deturgescence, so basic to the pathogenesis of corneal diseases. Furthermore, we point out how alterations of receptor-mediated control of these responses account for losses in corneal transparency. In particular, the roles of growth factors in the mediation of normal corneal function, including epithelial cell proliferation, prevention of compromise of the barrier function of the cornea, and maintenance of normal renewal processes are discussed in relation to clinical entities involving the cornea.
RESUMO
Revimos os eventos de sinalização celular mediados por receptores de fatores de crescimento, usados para manter a saúde do epitélio da córnea. O objetivo é mostrar como essas respostas contribuem para manter a transparência e a deturgescência da córnea, críticos na patogênese das doenças da córnea. Mais ainda, enfatizamos como alterações no controle mediado por receptor dessas respostas contribuem na transparência da córnea. Especificamente, o papel dos fatores de crescimento na mediação do controle funcional normal da córnea, incluindo proliferação epitelial, prevenção da quebra da função de barreira, manutenção do processo de renovação são discutidos em relação às entidades clínicas envolvidas na córnea.
