Abstract:

Mitogen-activated protein kinases (MAPKs) have been demonstrated to regulate flagellar/ciliary motility of spermatozoa and miracidia of Schistosoma mansoni. However, the role of MAPKs in mediating flagella-driven motility of Leishmania donovani is unexplored. We investigated the function of MAPKs in motility regulation of L. donovani using pharmacological inhibitors and activators of various MAPKs and fast-capture videomicroscopy. Our studies have revealed that the inhibitor of p38 MAPK, PD 169316, significantly affected various motility parameters such as flagellar beat frequency, parasite swimming speed, waveform of the flagellum and resulted in reduced parasite motility. Together, our results suggest that a MAPK, similar to human p38 MAPK, is implicated in flagellar motility regulation of L. donovani.
