Leukocyte elastase was demonstrated immunohistochemically not only in PMN-leukocytes in subcutaneous abscesses but also in scattered macrophage-like cells which in addition contained immunoreactive alpha 1-proteinase inhibitor (alpha 1PI) and alpha 2-macroglobulin (alpha 2M). These cells were located mainly in the marginal region of the abscess. It is concluded that the intracellular deposits in the macrophage-like cells represent phagocytized elastase and/or elastase-alpha 1PI and elastase-alpha 2M complexes. A contributing, local production of the inhibitor is, however, not excluded by the present findings.
免疫组织化学显示,白细胞弹性蛋白酶不仅存在于皮下脓肿中的中性粒细胞中,还存在于散在的巨噬细胞样细胞中,这些细胞还含有免疫反应性α1-蛋白酶抑制剂(α1PI)和α2-巨球蛋白(α2M)。这些细胞主要位于脓肿的边缘区域。可以得出结论,巨噬细胞样细胞中的细胞内沉积物代表吞噬的弹性蛋白酶和/或弹性蛋白酶-α1PI以及弹性蛋白酶-α2M复合物。然而,目前的研究结果并不排除抑制剂存在局部产生的情况。
