LTR-based synthetic peptides stimulate IL-6 release in PBMCs. Synthetic peptides, at the indicated concentrations, were added to PBMCs for 24 h, and the conditioned supernatants were assayed for IL-6 by ELISA. TR1 refers to 1 repeat (12 amino acids), TR2 to 2 repeats, and so on. For the sequence of the repeats, see Table .
