Cranial irradiation inhibits hippocampal neurogenesis via DNMT1 and DNMT3A
Impairment of neurogenesis in the hippocampus following whole-brain irradiation is the most important mechanism of radiation-induced cognitive dysfunction. However, the underlying mechanism remains obscure, meaning an ideal therapeutic target has not been identified. Evidence indicates that DNA methylation in neurons regulates synaptic plasticity and neuronal network activity. In the present st...
متن کاملAdult Hippocampal Neurogenesis and Memory
Adult neurogenesis, a concept emergent in the late 1990s, is the generation of new neurons in the adult brain. This process occurs thank to cells who have this proliferative feature, named as Neural Stem Cells (NSCs). Neural Stem Cells (NSCs) are primary progenitors who can generate the two neural types (neurons and glia). Classically it was assumed that NSCs are only present in the embryo, but...

متن کاملPrenatal Stress Inhibits Hippocampal Neurogenesis but Spares Olfactory Bulb Neurogenesis
The dentate gyrus (DG) and the olfactory bulb (OB) are two regions of the adult brain in which new neurons are integrated daily in the existing networks. It is clearly established that these newborn neurons are implicated in specific functions sustained by these regions and that different factors can influence neurogenesis in both structures. Among these, life events, particularly occurring dur...
متن کاملInterleukin-17 inhibits Adult Hippocampal Neurogenesis
Interleukin 17(A) (IL-17) is a potent pro-inflammatory cytokine that acts as a central regulator of inflammatory response within the brain, but its physiological roles under non-inflammatory conditions remain elusive. Here we report that endogenous IL-17 ablates neurogenesis in the adult dentate gyrus (DG) of hippocampus. Genetic deletion of IL-17 increased the number of adult-born neurons in t...
