Abstract
Chlamydia trachomatis-infected macrophages induce T cell apoptosis. This ability might promote intracellular survival of Chlamydia and perpetuate chronic chlamydial infection. The purpose of this study was to examine the molecular mechanisms by which C. trachomatis-infected macrophages induce T cell apoptosis. Monocytes and T cells were isolated from the peripheral blood of healthy donors. Macrophages were infected with C. trachomatis, and autologous T cells were stimulated by mitogen. After 6 days, both populations were cultured together using a two-chamber transwell membrane system to differentiate between mechanisms involving either cell-to-cell contact or secretion of apoptotic factors. Apoptotic T cells were identified by propidium iodide through-flow cytometry, and tumor necrosis factor-α (TNF-α) concentrations were measured by enzyme-linked immunosorbent assay. Antagonists of TNF-α, the Fas (CD95) molecule, TNF-related apoptosis-inducing ligand (TRAIL), and catalase were added to differentiate between the pathways of apoptosis. C. trachomatis-infected macrophages significantly induced T cell apoptosis by cell-to-cell contact (mean ± standard deviation, 30±4%; P<0.001) and by humoral mechanisms (mean ± standard deviation, 22±3%, P<0.001). Humoral apoptosis was mediated by secretion of TNF-α from infected macrophages. Inhibition of secretory TNF-α by the monoclonal anti-TNF-α antibody adalimumab (D2E7) blocked T cell death in vitro. In contrast, T cell apoptosis mediated by cell-to-cell contact was not inhibited by the different anti-apoptotic reagents. In summary, TNF-α derived from infected macrophages is an important apoptosis factor for T cell apoptosis induced by C. trachomatis-infected cells.
