Percentage of apoptotic pneumocytes treated with HZ. The number of apoptotic cells from EB/AO and annexin V-FITC/PI staining was calculated from line graphs. (a, b) At 1 h post-exposure, the group with the fastest cellular apoptotic induction was HZ-IL-1β. CPT and HZ alone groups were the next to reach high apoptosis levels after 6 and 12 h exposure times. At 24 h post-exposure, the HZ-IL-1β groups had higher numbers of apoptotic cells than those of the CPT-, HZ- and no-treatment groups.
