With the aid of monoclonal antibodies, macrophages can be split into functionally distinct subpopulations on the basis of their phenotype. Absence of macrophage subtypes has been noted in chronic inflammatory processes, e.g. posttraumatic osteomyelitis, rheumatoid arthritis and sarcoidosis. In the inflammatory focus of acute septic arthritis (n = 13 patients) however, macrophages constitute the majority of immunocompetent cells. The inflammatory macrophage subtype 27E10 was clearly present in increased numbers in 11 of 13 biopsies from the inflammatory foci, showing the effector task of this subtype in synovial resistance. The anti-inflammatory macrophage subset RM3/1 was present in increased numbers in biopsies of infected tissue and the surrounding soft tissue. The occurrence of 25F9-positive macrophages, typical of the late phase of inflammation, varied widely in the biopsies. [ABSTRACT FROM AUTHOR] |
