説明
<jats:p><jats:bold>Abstract</jats:bold> We have documented changes in expression of collagenolytic/gelatinolytic enzymes of the matrix metalloproteinase family (MMP) in healing or ulcerating corneal wounds of rat or rabbit. Correlation of our findings with specific changes in the extracellular matrix of the repair tissue suggests two different roles for the enzymes, MMP‐2 and MMP‐9. MMP‐2 is expressed in undamaged corneal stroma where it may degrade the occasional collagen molecule that becomes damaged. After corneal wounding, expression of this enzyme is increased and much of it appears in the active form. These changes persist for at least seven months, suggesting that MMP‐2 is involved in the prolonged process of collagen remodelling in the stromal repair tissue. MMP‐9 is expressed in the epithelial layer of repair tissue with a timing suggesting it might participate in controlling resynthesis of the basement membrane. MMP‐9 also appears to be involved in degradation of the epithelial basement membrane that precedes corneal ulceration.</jats:p>
