Harmonic activity of glutamate dehydrogenase and neuroplasticity: The impact on aging, cognitive dysfunction, and neurodegeneration.
In recent years, glutamate has attracted significant attention for its roles in various brain processes. However, one of its key regulators, glutamate dehydrogenase (GDH), remains understudied despite its pivotal role in several biochemical pathways. Dysfunction or dysregulation of GDH has been implicated in aging and various neurological disorders, such as Alzheimer's disease and Parkinson's disease. In this review, the impact of GDH on aging, cognitive impairment, and neurodegenerative conditions, as exemplars of the phenomena that may affected by neuroplasticity, has been reviewed. Despite extensive research on synaptic plasticity, the precise influence of GDH on brain structure and function remains undiscovered. This review of existing literature on GDH and neuroplasticity reveals diverse and occasionally conflicting effects. Future research endeavors should aim to describe the precise mechanisms by which GDH influences neuroplasticity (eg. synaptic plasticity and neurogenesis), particularly in the context of human aging and disease progression. Studies on GDH activity have been limited by factors such as insufficient sample sizes and varying experimental conditions. Researchers should focus on investigating the molecular mechanisms by which GDH modulates neuroplasticity, utilizing various animal strains and species, ages, sexes, GDH isoforms, brain regions, and cell types. Understanding GDH's role in neuroplasticity may offer innovative therapeutic strategies for neurodegenerative and psychiatric diseases, potentially slowing the aging process and promoting brain regeneration.
期刊介绍:
Behavioural Brain Research is an international, interdisciplinary journal dedicated to the publication of articles in the field of behavioural neuroscience, broadly defined. Contributions from the entire range of disciplines that comprise the neurosciences, behavioural sciences or cognitive sciences are appropriate, as long as the goal is to delineate the neural mechanisms underlying behaviour. Thus, studies may range from neurophysiological, neuroanatomical, neurochemical or neuropharmacological analysis of brain-behaviour relations, including the use of molecular genetic or behavioural genetic approaches, to studies that involve the use of brain imaging techniques, to neuroethological studies. Reports of original research, of major methodological advances, or of novel conceptual approaches are all encouraged. The journal will also consider critical reviews on selected topics.
