Sildenafil Enhances Neurogenesis and Oligodendrogenesis in Ischemic Brain of Middle-Aged Mouse

Adult neural stem cells give rise to neurons, oligodendrocytes and astrocytes. Aging reduces neural stem cells. Using an inducible nestin-CreER(T2)/R26R-yellow fluorescent protein (YFP) mouse, we investigated the effect of Sildenafil, a phosphodiesterase type 5 (PDE5) inhibitor, on nestin lineage neural stem cells and their progeny in the ischemic brain of the middle-aged mouse. We showed that ...

Endogenous Neurogenesis, Oligodendrogenesis and Angiogenesis after Ischemic Brain Injury

Strokes are a major cause of death and result in a drastic reduction in the quality of life. The only effective therapeutic approach is thrombolysis with recombinant tissue plasminogen activator, and a new strategy to minimize ischemic-related damage is thus required. Over the past 10 years, regenerative therapy, which supplies new neurons or oligodendrocytes, has been extensively studied. Two ...

Ventromedial prefrontal cortex stimulation enhances memory and hippocampal neurogenesis in the middle-aged rats

Memory dysfunction is a key symptom of age-related dementia. Although recent studies have suggested positive effects of electrical stimulation for memory enhancement, its potential targets remain largely unknown. In this study, we hypothesized that spatially targeted deep brain stimulation of ventromedial prefrontal cortex enhanced memory functions in a middle-aged rat model. Our results show t...

Exercise enhances learning and hippocampal neurogenesis in aged mice.

Aging causes changes in the hippocampus that may lead to cognitive decline in older adults. In young animals, exercise increases hippocampal neurogenesis and improves learning. We investigated whether voluntary wheel running would benefit mice that were sedentary until 19 months of age. Specifically, young and aged mice were housed with or without a running wheel and injected with bromodeoxyuri...

Stroke-induced neurogenesis in aged brain.

BACKGROUND AND PURPOSE Stroke induced by middle cerebral artery occlusion (MCAO) triggers increased neurogenesis in the damaged striatum and nondamaged hippocampus of young adult rodents. We explored whether stroke influences neurogenesis similarly in the aged brain. METHODS Young adult (3 months) and old (15 months) rats were subjected to 1 hour of MCAO, and new cells were labeled by intrape...
