FIG. 2.

Cholesteryl ester levels in uninfected (open circles) and C. pneumoniae-infected (solid circles) macrophages. Cells were infected (MOI = 2) or not infected for 2 h, washed twice, and incubated with various doses of LDL for 24 h. Cholesteryl ester levels were normalized to protein content. Data are representative of three experiments and are reported as means of triplicates with SD. ∗, statistically significant difference compared with infected samples cultured without exogenous LDL, P < 0.05 (t test).
