Summary
Aging causes changes in the neuromuscular junction (NMJ), impacting voluntary movement. This review covers NMJ aging in humans and rodents, and factors for repair.
Area of Science:
- Neuroscience
- Cell Biology
- Gerontology
Background:
- The neuromuscular junction (NMJ) is critical for voluntary movement and cell survival.
- Aberrant changes at the NMJ are linked to aging, diseases, and injuries.
- Understanding NMJ alterations is key to addressing age-related functional decline.
Purpose of the Study:
- To review morphological and molecular changes in aging NMJs.
- To explore factors involved in maintaining and repairing aged NMJs.
- To provide insights into NMJ health across the lifespan.
Main Methods:
- Review of existing literature on NMJ aging.
- Analysis of morphological changes in rodent and human NMJs.
- Molecular analysis of NMJ components during aging.
Main Results:
- Aging is associated with significant morphological and molecular alterations at the NMJ.
- Changes occur across all three cellular components: presynaptic, postsynaptic, and perisynaptic Schwann cells.
- Specific factors influencing NMJ maintenance and repair in aged individuals have been identified.
Conclusions:
- Aging profoundly affects neuromuscular junction structure and function.
- Targeting specific molecular and cellular pathways may aid in NMJ repair and maintenance.
- Further research into NMJ aging is crucial for developing interventions against age-related mobility loss.

33.7K
In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.

01:54Base Excision Repair
26.3K
One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

2.8K
The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...
