Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists01:30

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

804
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.

Epigenetic Regulation01:37

Epigenetic Regulation

4.1K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Cognitive Development During Adulthood

1.1K
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Chromatin Modification in iPS Cells

2.3K
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...

Area of Science:

  • Neuroscience
  • Genetics
  • Pharmacology

Background:

  • Age-related cognitive decline is a significant societal issue.
  • Epigenetic modifications, including histone acetylation, play a crucial role in gene transcription.
  • Aging disrupts the balance of epigenetic modifications, impacting gene expression.

Purpose of the Study:

  • To discuss evidence on age-related modulation of gene transcription by epigenetic modifications.
  • To explore the role of histone acetylation and deacetylation in aging-related cognitive deficits.
  • To present histone deacetylase inhibitors as a potential therapeutic strategy.

Main Methods:

  • Review of recent evidence on epigenetic modifications and aging.
  • Analysis of the impact of histone acetylation/deacetylation balance on gene expression.
  • Discussion of pharmacological interventions targeting histone deacetylase.

Main Results:

  • Aging is associated with an imbalance in epigenetic modifications, specifically increased histone deacetylation.
  • This imbalance limits the expression of plasticity-related genes, contributing to cognitive decline.
  • Histone deacetylase inhibitors can shift the balance towards histone acetylation.

Conclusions:

  • Epigenetic modifications are key regulators of age-related cognitive changes.
  • Targeting histone deacetylase offers a promising pharmacological avenue to improve cognitive function in aging.
  • Further research into histone deacetylase inhibitors could lead to effective treatments for cognitive deficits.
