Citrulline results in increased protein levels of ABCA1 and ABCG1 in human monocyte derived macrophages (MDM). The monocytes were cultured and differentiated into macrophages in the presence of autologous sera obtained from 8 subjects before and 1 week after placebo or citrulline consumption as describe in Materials and Methods. MDM were lysed and subjected to a Western blot analysis. Protein levels were quantified as described in Materials and Methods. Independent experiments from 8 different subjects are expressed as the mean ± SEM. *Different from 0 week-citrulline, p<0.05.
