Application of new methods and technologies in mice models of autism research
Nováková, Rozálie ; Kubik-Zahorodna, Agnieszka (advisor) ; Telenský, Petr (referee)
Autism Spectrum disorder (ASD) is a neurodevelopmental disorder affecting around 2 % of the world's population. The underlying pathology is still unknown, but it seems that this disorder might be caused by a complex combination of genetic, epigenetic and environmental factors. ASD individuals suffer not only from repetitive behavior, abnormal social behavior and impaired communication but also from many comorbid disorders. ASD mouse models offer a deeper insight into the pathology of ASD, possibly leading to the development of treatments, or even a cure. Since there are over a thousand risk-genes for ASD, and therefore many ASD mouse models, there is an increased pressure to develop new, effective, and more automatized behavioral assays. Two examples of this would be Intellicage and Digitally Ventilated Cage (DVC), where an explicit advantage to these systems is that they can both function as a home cage. Intellicage is a fully-automized home cage designed for the high-throughput and long-term investigation of spontaneous behavior and cognitive abilities of mice, and DVC, a standard IVC cage continuously measuring a mouse's activity. These may become useful tools not only for animal models of Autism Spectrum Disorder, but all studies involving behavioral assays.

Comparison of transgenic and streptozotocin models of Alzheimer in rats: validation of IntelliCage system for behavioral phenotypization
Svobodová, Eva ; Telenský, Petr (advisor) ; Svoboda, Jan (referee)
Animal models of Alzheimer's disease display cognitive insufficiencies which mimic human symptoms and occur at a given age or post-treatment time. Animals are typically tested using canonical behavioral tests, lasting minutes and taking place mostly in the non-active period of the daily cycle. Animals are exposed to certain amounts of manipulation-induced stress. Our work represents a validation study for the rat behavioral system IntelliCage. The tested individuals live freely in a group and their behavior is monitored continuously. It is however possible to set up individual tests for each animal or a group of animals. The rats are not subject to human manipulation and hence the results are not affected by manipulation-induced stress. We tested early cognitive impairment in the transgenic rat model TgF344-AD at 6 - 8 months of age. Further, we tested two most common protocols of the streptozotocin model, i.e. single dose of intracerebroventricular 3 mg/kg streptozotocin and double dose 48 hrs apart. Results were compared with the canonical Morris Water Maze (MWM) test. In the MWM test, transgenic animals did not differ from controls in any of the studied parameters. The streptozotocin model displayed a deficit only in the double dose group. However in the IntelliCage, transgenic animals displayed...
