Nonetheless, the fact that the 20 week library A granulomas (most of which have succeeded in killing many of the bacteria within them[14, 17]) and the 4 week library B granulomas in the same animals shared this increased IL-10+ T cell profile suggests that the Library B granulomas are primed to quickly dispense with the infection, with IL-10 production being one factor associated with that clearance. Here, IL10 is linked to infection.
