Th1-mediated cellular responses are important for protection in
tuberculosis. However, the mechanisms and APC types responsible for
initiating Th1 responses are not well understood. These studies show
that macrophages and dendritic cells, albeit both being APC, respond
differently following Mycobacterium tuberculosis
infection and thereby have different consequences for the development
of naive T cells. We report that M.
tuberculosis-infected dendritic cells bias the polarization of
OVA peptide-specific naive transgenic T cells to the Th1 phenotype,
and, in contrast, in the presence of infected macrophages naive T cells
do not develop a Th1 phenotype. Comparison of the cytokine profile
expressed by the infected dendritic cells and macrophages revealed
several differences, the most striking being that infected macrophages
did not express the Th1-promoting cytokine IL-12. These studies also
show that IL-10 is responsible for the failure of IL-12 production by
M. tuberculosis-infected macrophages, and that the
effects of IL-10 can be overcome by IFN-
priming. We speculate that
the observed difference in response of the two APC types to M.
tuberculosis infection may be a reflection of their respective
roles in immune initiation and granuloma
regulation.
