We previously found an abnormal deposition of an extracellular matrix glycoprotein, tenascin-C (TN-C), in human corneas with pseudophakic/aphakic bullous keratopathy (PBK/ABK). In this work, we studied cellular TN-C receptors in normal and PBK/ABK corneas. Cryostat sections of normal and PBK/ABK corneas were stained by immuno-fluorescence for TN-C receptors: alpha2, alpha8, alpha9, alphaVbeta3, beta1, and beta6 integrins, and annexin II. Beta6 integrin mRNA levels were assessed by semiquantitative reverse transcription-polymerase chain reaction (RT-PCR) using beta2-microglobulin gene to normalize the samples. In PBK/ABK compared to normal corneas, relatively minor changes were observed for alpha2 and beta1 integrins, and for annexin II. Alpha8, alpha9, and beta6 subunits of TN-C receptors, alpha8beta1 alpha9beta1, and alphaVbeta6, respectively, were absent from normal central corneas but were found in the central epithelium of PBK/ABK corneas. Beta6 integrin showed the most significant accumulation. It correlated best with the expression of TN-C rather than with the expression of other alphaVbeta6 ligands, fibronectin, and vitronectin. RT-PCR analysis also showed elevated levels of beta6 mRNA in PBK/ABK compared to normal corneas. Therefore, accumulation of TN-C in PBK/ABK corneas was accompanied by an increased expression of its three binding integrins, especially alphaVbeta6 in the corneal epithelium. The interaction of tenascin-C with these integrins may contribute to the fibrotic process that occurs in PBK/ABK corneas.
