Epigenetic signature in neural plasticity: the journey so far and journey ahead
Open accessAbstract
Neural plasticity is a remarkable characteristic of the brain which allows neurons to rewire their structure in response to internal and external stimuli. Many external stimuli collectively referred to as 'epigenetic factors' strongly influence structural and functional reorganization of the brain, thereby acting as a potential driver of neural plasticity. DNA methylation and demethylation, histone acetylation, and deacetylation are some of the frontline epigenetic mechanisms behind neural plasticity. Epigenetic signature molecules (mostly proteins) play a pivotal role in epigenetic reprogramming. Though neuro-epigenetics is an incredibly important field of emerging research, the critical role of signature proteins associated with epigenetic alteration and their involvement in neural plasticity needs further attention. This study gives an integrated and systematic overview of the current state of knowledge with a clear idea of types of neural plasticity and the context-dependent role of epigenetic signature molecules and their modulation by some natural bioactive compounds.

At the molecular level, synaptic plasticity processes are supported by glutamatergic signaling through NMDA and AMPA receptors, neurotrophins such as BDNF, intracellular signaling cascades, and dynamic interactions with astrocytes and microglia.
“At the molecular level, these processes are supported by glutamatergic signaling through N-Methyl-D-aspartic acid (NMDA) and α-Amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors, neurotrophins such as brain-derived neurotrophic factor (BDNF), intracellular signaling cascades, and dynamic interactions with astrocytes and microglia [82, 83].”

The sections on NMDAR-dependent LTP/LTD and BDNF-dependent plasticity support the roles of NMDA and AMPA receptors, BDNF, and intracellular signaling pathways. Our copy does not support the attributed claim about dynamic interactions with astrocytes and microglia; searches for both terms found no relevant passage.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
