(A) IL-12p70 in supernatants from non-treated BMDC(NT), BMDC infected (Inf) with L. major promastigotes at 48 hours p.i., BMDC stimulated with parasite lysate (LmAg), or with heat-killed parasites (HK), for 48 hours. (B) IL-12p40 and (C) IL-10 concentration in supernatants of BMDC at 48 hours p.i., or stimulation with LmAg or HK parasites. (D) IL-12p70 production in supernatants from non-treated BMM (NT), BMM infected (Inf) with L. major promastigotes at 48 hours p.i., and BMM stimulated for 48 hours with LmAg or HK parasites. (E) IL-12p40 and (F) IL-10 concentration in supernatants of BMM at 48 hours p.i., or stimulation with either LmAg or HK parasites. The results are expressed as mean ± SD of 5 independent experiments. For each experimental group (NT, Inf, LmAg and HK), statistical significance was estimated between WT and Ctsb−/− cells, and between WT and Ctsl−/− cells, * p<0.05, **p<0.01, *** p<0.005.
