Fig 4. Ii intermediates were detected in DCs+B cells by IP.

(A) Ii intermediates, LIP, SLIP and p10 accumulated when cells were treated with 10 μg E64 or transinfected with 2 μg px458-253 vector first and incubated with M.hp later. (B) less LIP or SLIP and no p10 accumulated in cells when cells overexpressed with 2 μg CTSL-GFP or add 30 μg rCTSL in vitro. Data are representative of three independent experiments.
