Hypothesis
Can oral supplementation with N-acetylcysteine restore synaptic plasticity in aged mice?
Conclusion
Oral supplementation with N-acetylcysteine can reverse age-related impairments in synaptic plasticity in the hippocampus of aged mice.
Supporting Evidence
- Aged mice showed a 39.8% decrease in brain GSH levels compared to adult mice.
- N-acetylcysteine supplementation increased GSH levels by 26.2% in aged mice.
- LTP in aged NAC-fed mice was restored to NMDAR-dependence, similar to adult mice.
Takeaway
Giving older mice a supplement can help their brains work more like younger mice, especially in learning and memory.
Methodology
Aged mice were supplemented with N-acetylcysteine for 21 days, and their synaptic plasticity was assessed through electrophysiological recordings.
Limitations
The study primarily focused on male C57BL/6 mice, which may limit the generalizability of the findings.
Participant Demographics
Adult (2-4 months old) and aged (14-18 months old) male C57BL/6 mice.
