Background & Aims: Cerebral ischemia is known as a major worldwide problem and subsequent reperfusion leads to apoptosis or programmed cell death. Specific regions of the brain and specific types of neurons, including hippocampal CA1 pyramidal neurons are more sensitive in cerebral ischemia. Today cell therapy is one of the common treatments that spread among the researchers. In this study, we...
Integration of new neurons into the adult hippocampus has been linked to specific types of learning. Primary cilia were found to be required for the formation of adult neural stem cells (NSCs) in the hippocampal dentate gyrus during development. However, the requirement of cilia in maintenance of adult NSCs is unknown. We developed a genetic mouse model in which fetal/perinatal brain developmen...
Background: Diabetes causes nerve tissue damage and ultimately death of nerve cells, especially in important areas such as the hippocampus. It seems that exercise training and anti-inflammatory supplements can moderate this condition. Therefore, the aim of this study was to determine the effect of aerobic training exercise and L-carnitine consumption on the levels of hippocampus CNTF and CNTFR ...
traumatic brain injury (tbi) is one the most common cause of disability between young adults. these people have been socially isolated during post-surgery traumatic brain injury. in this study we investigated the effect of social isolation on the structural deficits after tbi in the young rats. young rats were divided into control group with social interaction, sham group with social isolation ...
Physiological body temperature is an important determinant for neural functions, and it is well established that changes in temperature have dynamic influences on hippocampal neural activities. However, the detailed molecular mechanisms have never been clarified. Here, we show that hippocampal neurons express functional transient receptor potential vanilloid 4 (TRPV4), one of the thermosensitiv...
Cellular proliferation, differentiation, integration, and survival within the adult neural stem cell niche are altered under pathological conditions, but the molecular cues regulating the biology of this niche are mostly unknown. We examined the hippocampal neural stem cell niche in a transgenic rat model of Huntington disease. In this model, progressive cognitive deficits develop at the age of...
Isolation and expansion of self-renewing neural cells ex vivo are required for neural tissue repair in regenerative medicine. Neurogenesis occurs in restricted areas of postnatal mammalian brain including dentate gyrus and subventricular zone. We developed a simple method to entrap migrating neural cells (potential neuroprogenitors) from postnatal hippocampal organotypic cultures in three-dimen...
INTRODUCTION Radiation therapy plays an essential role in the treatment of brain tumors, but neurocognitive deficits remain a significant risk, especially in pediatric patients. In recent trials, hippocampal sparing techniques are applied to reduce these adverse effects. Here, we investigate dose-dependent effects of ionizing radiation (IR) on juvenile hippocampal neurogenesis. Additionally, we...
