Incorporation of [ methyl -3H]choline labelled LDL into L929 cells, PC, LPC and aqueous fraction. L929 cells were infected with C. trachomatis at a multiplicity of infection of 3 to 5 CFU. At 22 h post infection (hatched bars) or post mock-infection (open bars), cells were incubated for 5 h with [3H]PC-LDL and radioactivity incorporated into A. L929 cells; B. PC; C. LPC; and D. aqueous fraction determined. Results represent the mean ± standard deviation of three dishes. *p < 0.05.
