Whole mount confocal microscopy output of leaves expressing human or mouse IL-10 fused to GFP.

<p>Highly mobile globular granules of up to 5 µm in size were observed traveling along cytoplasmic and/or ER strands for SP-hIL-10-GFP only. (A) GFP preceded by the <i>Arabidopsis thaliana</i> chitinase signal peptide for secretion (SP-GFP). (B/C) The native open reading frame of human (h) and mouse (m) IL-10 including the native signal peptide (SP) with GFP fused C-terminally.
