Fig. 1From: Extracellular release of virulence factor major surface protease via exosomes in Leishmania infantum promastigotesTransmission electron microscopy of the secreted nanovesicles. The secreted nanovesicles from the stationary promastigotes of L. infantum were processed and examined by TEM. The size and morphology of the secreted nanovesicles from logarithmic and metacyclic promastigotes were similar (not shown). Scale-bar: 200 nmBack to article page
