(A) BMDMs were infected with G217B yeast cells at an MOI of 5. At various time points post-infection, total RNA was isolated from BMDMs and TRB3 expression was monitored by quantitative RT-PCR. Fold induction was calculated relative to the uninfected 0-hour sample. (B) To monitor macrophage lysis, supernatants from the same infected macrophages assayed in (A) were subjected to LDH release analysis. (C) BMDMs were either mock-infected (uninfected) or infected with wild-type G217B ura5Δ+URA (wild-type) or cbp1+URA mutant cells (cbp1) at an MOI of 10. Lysis of the macrophage monolayer infected with wild-type cells was complete by 48 hpi. At the indicated times post-infection, total RNA was isolated from BMDMs and TRB3 expression was monitored by quantitative RT-PCR. Fold induction was calculated relative to the mock-infected 24-hour sample. (D) BMDMs were either mock-infected (uninfected) or infected with wild-type G217B ura5Δ+URA (wild-type), cbp1+URA mutant cells (cbp1), or the complemented strain (cbp1+CBP1) at an MOI of 2. At the indicated times post-infection, total RNA was isolated from BMDMs and TRB3 expression was monitored by quantitative RT-PCR. Fold induction was calculated relative to the mock-infected 0-hour sample.
