  • Title: Uptake of immunoreactive leukocyte elastase-inhibitor complexes in macrophage-like cells in abscesses.
    Author: Delshammar M, Lasson A, Ohlsson K.
    Journal: Eur Surg Res; 1991; 23(3-4):256-60. PubMed ID: 1723685.
    Abstract:
    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.
