CD11c⁺CD11b^+/- cells deliver T gondii into the brain. (A) Accumulation of CD11c⁺CD11b^+/- and CD11c^-CD11b⁺ cells in the brain of infected C57BL/6 mice previously engrafted with GFP⁺ bone marrow cells. (B) Number of parasites harbored by GFP⁺ brain cells from naive or infected chimeric mice. Values represent mean number plus SD for 3 to 5 mice per group. (C) Dot plots of CD11c⁺ and CD11b⁺ GFP⁺ cells naive or infected chimeric mouse brains. Brain GFP⁺ cells were isolated by FACS and stained. Numbers are the total CD11c⁺ or CD11b⁺ GFP⁺ cells per brain. Data are from a single experiment, representative of 2 separate experiments.
