Microbial symbionts can modulate host interactions with biotic and abiotic factors. Such interactions may affect the evolutionary trajectories of both host and symbiont. Wolbachia protects Drosophila melanogaster against several viral infections and the strength of the protection varies between variants of this endosymbiont. Since Wolbachia is maternally(More)
Wolbachia are intracellular symbionts of many species of animals, mostly arthropods. Vertical transmission of Wolbachia is exclusively maternal and this endobacterium promotes reproductive manipulations of its hosts, increasing the fitness of infected females. Moreover, Wolbachia provides its hosts with a wide range of adaptive features ranging from(More)
A high concentration of selegiline ((-)-deprenyl; 10(-4) M) potentiated low frequency (2 Hz) nerve stimulation-evoked release of [3H]noradrenaline from the isolated main pulmonary artery of the rabbit in the presence of neuronal (cocaine, 3 X 10(-5) M) and extraneuronal (corticosterone, 5 X 10(-5) M) uptake blockers, and inhibited the postsynaptic response.(More)
Vinpocetine (10(-6)-3 X 10(-5) M) increased both the resting and the nerve stimulation-evoked release of [3H]noradrenaline from the isolated main pulmonary artery of the rabbit in the presence of uptake blockers (cocaine, 3 X 10(-5) M; corticosterone, 5 X 10(-5) M), and inhibited the nerve stimulation-evoked postsynaptic response. The resting transmitter(More)
