Influence of the recombinant TM protein of HERV-K on the proliferation of ConA-stimulated PBMCs from one healthy human blood donor (a, b) or murine splenocytes (c).

<p>Cell proliferation was measured using the Alamar blue assay (<b>a, c</b>) or by ³H-thymidine incorporation (<b>b</b>) (mean±SD; n = 3). ³H-thymidine was added on day three and cells were then harvested one the next day and the counts per minute were determined, dark gray – isu peptide-BSA conjugates, gray – BSA conjugates, added at day 0. Black (Pos, positive control) – medium alone.
