Figure 2. Lm-induced pro-inflammatory cytokine production in P2X5-deficient mice.
(a) IL-12p40 and IFN-γ were measured from collected serum at days 0, 1 and 2 post-Lm infection by ELISA. (b) Splenocytes from mice 0, 1 and 2 days post-Lm infection were cultured with or without HKLM stimulation for 4 hr in the presence of BFA and stained for intracellular TNF-α with surface staining for CD4, CD8a, and CD11b. Cell numbers are gated from non-CD4, CD8 and CD11bint TNF-αhi lymphocytes/monocytes. Data are representative of at least two independent experiments. (**p < 0.01)
