ABSTRACT
In this study, we report a new approach that allows dissection of distinct pathways regulating induction of early adaptive immunity in response to Mycobacterium tuberculosis (Mtb). We used traceable murine dendritic cells (DCs) and macrophage populations to chart their migratory pattern in response to Mtb, and found that only DCs receiving inflammatory stimuli from Mtb up-regulated their expression of CCR7 and migrated specifically to the draining lymph nodes (LNs). Furthermore, these Mtb-modulated DCs initiated a Th1 response only in the draining LNs. Taken together, these results demonstrate that Mtb-induced modulation of DCs is critical for their migration to regional LNs and ensuing T cell priming.
