Abstract:
Alzheimer's disease and other neurodegenerative disorders are major health and economic problems. The main emphasis on treating these disorders has been based on the idea of targeting the amyloid pathway, but these efforts have not yielded effective disease-modifying therapies. In this article, I review arguments in favor of "calcium hypothesis of neurodegeneration" that offer additional targets that may potentially be explored. The main limitation in translation of this idea to the clinic has been concern about potential side effects of calcium channel blockers and inhibitors of calcium signaling enzymes in nonneuronal tissues. I reason that recently developed positive allosteric modulators of sarco-endoplasmic reticulum calcium (SERCA) pump may be able to solve this problem and briefly review results supporting this claim. If this class of compounds is proven safe in humans in clinical trials, they would offer promising therapeutic leads for developing disease-modifying therapy for a variety of neurodegenerative disorders.
Insights
The amyloid pathway has failed to treat neurodegenerative diseases. Exploring the calcium hypothesis, particularly with SERCA pump modulators, offers new therapeutic targets for Alzheimer's and similar disorders.
Area of Science:
- Neuroscience
- Pharmacology
Background:
- Alzheimer's disease and other neurodegenerative disorders represent significant health and economic burdens.
- Current therapeutic strategies primarily target the amyloid pathway, but have not resulted in effective disease-modifying treatments.
Purpose of the Study:
- To review evidence supporting the "calcium hypothesis of neurodegeneration" as an alternative therapeutic avenue.
- To address the clinical translation challenges of calcium signaling modulation.
Main Methods:
- Review of existing literature on the calcium hypothesis of neurodegeneration.
- Discussion of potential therapeutic agents, including positive allosteric modulators of the sarco-endoplasmic reticulum calcium (SERCA) pump.
Main Results:
- The amyloid pathway has shown limited success in treating neurodegenerative diseases.
- Concerns regarding side effects of traditional calcium channel blockers hinder clinical application.
- Positive allosteric modulators of SERCA pumps present a potential solution to mitigate side effects.
Conclusions:
- The calcium hypothesis offers promising alternative targets for neurodegenerative disorders.
- SERCA pump modulators may overcome previous safety concerns, offering new therapeutic leads.
- Further clinical trials are necessary to validate the safety and efficacy of SERCA modulators in humans.
