Neuroplasticity

Neuroplasticity

Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

Chromatin Modification in iPS Cells

Chromatin Modification in iPS Cells

Chromatin modification alters gene expression; therefore, scientists can add histone-modifying enzymes, histone variants, and chromatin remodeling complexes to somatic cells to aid reprogramming into pluripotent stem (iPS) cells.
Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...

Long-term Potentiation

Long-term Potentiation

Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

Neurogenesis and Regeneration of Nervous Tissue

Neurogenesis and Regeneration of Nervous Tissue

In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Background:

Excitatory communication predominantly occurs at dendritic spines.
Spine modifications are closely linked to synaptic modifications in both healthy and diseased states.
The precise roles and molecular underpinnings of spine remodeling in synaptic plasticity remain incompletely understood.

Purpose of the Study:

To review recent advancements in understanding dendritic spine remodeling.
To discuss the functional implications of spine remodeling, encompassing changes in spine size and actin dynamics.
To propose distinct contributions of these actin remodeling aspects to synaptic modification.

Main Methods:

Literature review of recent research on dendritic spine remodeling.
Analysis of studies investigating spine size alterations.
Examination of research focusing on actin dynamics within dendritic spines.

Main Results:

Spine remodeling, including alterations in spine size and actin dynamics, is essential for synaptic modification.
These two facets of actin remodeling appear to play separate roles in the process of synaptic modification.
Recent progress highlights the complexity and distinct functional contributions of spine remodeling processes.

Conclusions:

Dendritic spine remodeling is a fundamental process underlying synaptic plasticity.
Alterations in spine size and actin dynamics represent key, yet distinct, mechanisms of spine remodeling.
Further research into the molecular mechanisms governing these distinct remodeling processes is warranted to fully elucidate their role in synaptic function and dysfunction.
