JNK isoforms control adult mammal hippocampal neurogenesis
[eng] In mammals, the term "Adult Neurogenesis” (AN) defines the process through which, throughout adulthood, new neurons are produced from neural stem cells (NSC). These NSC are located in a specific niche, concretely, in the subventricular zone (SVZ), lining the lateral ventricles, and in the...

| Sumario: | [eng] In mammals, the term "Adult Neurogenesis” (AN) defines the process through which, throughout adulthood, new neurons are produced from neural stem cells (NSC). These NSC are located in a specific niche, concretely, in the subventricular zone (SVZ), lining the lateral ventricles, and in the subgranular zone (SGZ) in the dentate gyrus (DG) of the hippocampus. Controversially, new data have questioned the existence of this AN in the human brain seeing how only populations of immature neurons (IN), broadly dispersed within SGZ, have been detected. Either way, neurogenic activity in the hippocampus has been correlated with learning, memory formation and behavioral responses to stress, just like with the pathophysiology of many brain diseases and mood disorders. Various extracellular and intracellular stimuli have been shown to modulate survival, proliferation, and differentiation of adult-born cells in the hippocampus, especially through conserved stimuli-response mechanisms like the JNKs. In the present review, the JNK pathway and their control of adult hippocampal neurogenesis are described, evidencing the critical role of isoform JNK1. |
