... features that underlie polarized sorting, a specialized region at the base of the axon and polarized microtubules, are found in invertebrate neurons as well. It thus seems likely that all bilaterians generate axons and dendrites in the same way. As a next step, it will be extremely interesting to determine...

.... In the euryhaline green shore crab Carcinus maenas , active excretion of ammonia across isolated gills is reduced by inhibitors of the Na + /K + -ATPase and vacuolar-type H + -ATPase. In addition, a functional dynamic microtubule network is necessary, since application of colchicine, taxol or thiabendazole leads...

... of more than one phagosome in the macrostome, indicating that membrane transport to the oral apparatus in macrostomes is guided by microtubules. Nocodazole has no effect on the process of phagocytosis in microstomes. We do not know the mechanisms whereby phagocytosis is initiated in ciliates( Allen...
