Abstract

The interactions between Chlamydia trachomatis and human blood mononuclear leukocytes were studied using flow cytometry, immunofluorescence, electron microscopy and cytokine assays. Under serum-free conditions, elementary bodies (EB) of C. trachomatis were found to bind to human T lymphocytes as well as to B cells and monocytes/macrophages (M phi). For all cell types the binding was saturable, rapid, temperature-independent and independent of the chlamydia-specific serological status of the donor. Similar proportions of T and B cells bound EB at similar levels. In the T cell population, proportionally less CD8+ cells bound EB. Whereas M phi phagocytosed and destroyed the bound micro-organism..
