I-54: New Models for Human and Mouse Genetic
The possibility to reprogram somatic human cells will greatly and deeply change genetic approach and allow the development of new tools to study genetics diseases. Indeed, our ability to study human genetic diseases suffers from the lack of valid in vitro models. The latter should (i) be originating from human primary cells, (ii) be able to self-renew for a long time and (iii) be able to differ...
متن کاملPrepulse-elicited startle in prepulse inhibition.
BACKGROUND Prepulse inhibition (PPI) has become a major experimental paradigm in the study of psychiatric disorders. In this study, a potential confound in measurement and interpretation of PPI, namely startle reactions to so-called "nonstartling" prepulses, was examined. METHODS Prepulses of 80, 85, and 90 dB(A) were presented on their own or followed by a pulse of 115 dB(A) (lead interval: ...
متن کاملAnalysis of prepulse inhibition in mouse lines overexpressing 22q11.2 orthologues.
Animal models have been useful in elucidating the genetic basis of the cognitive and behavioural phenotypes associated with the 22q11.2 microdeletions. Loss-of-function models have implicated a number of genes as playing a role in prepulse inhibition (PPI) of the startle response. Here, we report the generation and initial analysis of bacterial artificial chromosome (BAC) transgenic (Tg) mice, ...
متن کاملEffects of early acoustic stimulation on prepulse inhibition in mice
The purpose of this study was to determine the effects of an atypical pattern of early acoustic stimulation on auditory development. Previous human research suggests that the acoustic environment of pre-term human infants in the Neonatal Intensive Care Unit (NICU) negatively affects some aspects of auditory development. Animal research suggests that premature auditory stimulation interrupts aud...
متن کاملA Cellular Mechanism for Prepulse Inhibition
In prepulse inhibition (PPI), startle responses to sudden, unexpected stimuli are markedly attenuated if immediately preceded by a weak stimulus of almost any modality. This experimental paradigm exposes a potent inhibitory process, present in nervous systems from invertebrates to humans, that is widely considered to play an important role in reducing distraction during the processing of sensor...
