Effect of PLTP on apoE secretion. ApoE was analyzed by ELISA in the media from MFC incubated with 10 μg/ml bovine serum albumin (BSA), 10 μg/ml apoA-I (apoA-I) or with 200 nmol/ml/h PLTP for 24h. Figure is representative for two independent experiments. Bars represent mean ± SD calculated from triplicates. * P < 0.05.
