Signal Transduction Mechanisms in Protozoa

摘要: Although protozoa are unicellular eukaryotes, they have developed signalling mechanisms to modulate fundamental activities such as acquisition of nutrients and reproduction. However, our knowledge signal transduction events in has lagged behind advances made this field more complex organisms. Nevertheless, evidence discussed review suggests that take place by similar those present higher namely, binding molecules specific receptors. This then results the activation pathways. The latter been studied detail ciliates, particular, opioid mechanism Tetrahymena Stentor, chemosensing Paramecium pheromone secretion Euplotes. These data suggest pathways metazoa originated evolution from eukaryotes.
