Fig. 2.

The release of CCL19 from mononuclear cells during highly active anti-retroviral therapy (HAART). The panels show the spontaneous (a, b) and phytohaemagglutinin (PHA)-stimulated (c, d) release of CCL19 in mononuclear cells from peripheral blood mononuclear cells (PBMC, left panels) and bone marrow (BM) aspirates (right panels) after culturing for 20 h in six healthy controls and in nine human immunodeficiency virus (HIV)-infected patients before (baseline) and at different time-points (weeks) after initiating HAART. The bold horizontal line indicates the mean of the observations (PHA final dilution 1:100).
