Homozygous male TaoEP1455 flies exposed to a moderate (non-sedating) concentration of ethanol exhibit reduced hyperactivity compared to wild type. This reduction in hyperactivity is present over a range of ethanol doses and is not observed in heterozygotes. The presence of the phenotype is dependent on the temperature during metamorphosis; flies at 25[o]C during pupariation exhibit reduced hyperactivity whereas locomotor activity in flies that metamorphose at 18[o]C is comparable to wild type. TaoEP1455 flies are not insensitive to ethanol, as naive flies startle normally on exposure, reaching speeds that are usually observed in the later phases of the hyperactivity response. The rate of ethanol accumulation is also similar to controls. TaoEP1455 flies are capable of normal locomotion, having an average walking speed that is comparable to wild type. As well as ethanol, TaoEP1455 mutant flies are also resistant to the effects of other drugs of abuse, exhibiting improved climbing behaviour in response to both cocaine and nicotine in comparison with control flies.
TaoEP1455/Tao50 males exhibit greatly diminished ethanol-induced hyperactivity compared to wild type.
The brains of TaoEP1455 mutant flies appear normal in size and gross morphology. However, striking differences are seen in the mushroom and ellipsoid bodies. The normally circular ellipsoid body appears open and flattened and the α and β lobes of the mushroom body are absent in most flies. The γ lobes are present but are often thinner than in wild type flies. No defects are observed in other components of the central complex, including the fan-shaped body and the cerebral bridge. However, a FasII-positive ball-like structure is present in the posterior of the brain, adjacent to the mushroom body calices.
