摘要

Based on our results, we can speculate that NCX1, by regulating microglia/astrocytes activation and polarization, might inter- fere with the neurogenic potential of astrocytes under ischemic conditions. During our daily life, we face stressful events to which our body generates responses and memories of these events are stored in order to cope with their future occurrence. Transducer of ErbB2 (Tob), a member of the Tob/BTG anti-proliferative family proteins, has been implicated in cell proliferation, differentiation and the DNA damage response. In the brain, there are reports suggesting that Tob regulates complex behavioral processes such as learning and memory. Interestingly, Tob knockout mice exhibited increased brain weights in conjunction with structural magnetic resonance imaging (MRI) which revealed increased volume compared to wild- type mice. Behavior analyses showed increased levels of anxiety and fear expression in Tob knockout mice. Additionally, fMRI anal- ysis for the functional connectivity between different brain parts in Tob-knockout mice revealed altered hippocampal and pre-frontal cortex connectivity, which might predispose for impaired stress handling in mice. Since Tob protein has been shown to be respon- sive to different stress stimuli, restraint stress for mice subjects has been utilized as a stress model in this study. The neuronal molecular pathway for Tob in response to stress involving dynamic phosphorylation signaling events and changes in neurotransmit- ter’s postsynaptic receptor levels will be elucidated. This study sets the stage for investigating the potential function of Tob in the brain in response to stress and involvement in neurological disorders.
