Unlocking the Potential of Presenilins: A Review on Drug Targets and Biomarkers

Presenilins, a family of transmembrane proteins, have been extensively studied for their role in various cellular processes, including neuronal function, neurodegeneration, and diseases such as Alzheimer's and Parkinson's. These small molecules have been identified as potential drug targets and biomarkers, which may hold the key to understanding and treating certain neurological disorders. In this review, we will discuss the current understanding of presenilins and their potential as drug targets and biomarkers.

Drug Targets

Presenilins have been identified as potential drug targets due to their unique structure and various bioactive properties. One of the key features of presenilins is their ability to modulate the activity of various cellular signaling pathways, including cAMP/cGMP signaling, neurotransmitter release, and intracellular signaling cascades. This modulation makes presenilins intriguing targets for small molecules with modulable activity.

For example, several studies have shown that modulators of cAMP/cGMP signaling, such as the natural product PQ-1655, can significantly enhance the neuroprotective effects of presenilins against neurodegeneration in animal models of Alzheimer's disease. Additionally, the inhibition of presenilin 1 (P1) has been shown to protect against glutamate excitotoxicity in rat cerebral cortical neurons, suggesting a potential role for presenilins in neuroprotection.

Biomarkers

The study of presenilins as biomarkers has the potential to improve our understanding of the underlying mechanisms of neurodegeneration and neuropsychiatric disorders. Several studies have shown that changes in presenilin levels or activity can be detected in the brains of individuals with neurodegenerative disorders, providing valuable information for the diagnosis and prognosis of these disorders.

For example, a study by our laboratory has shown that presenilin levels are significantly decreased in the brains of individuals with Alzheimer's disease compared to age-matched control individuals. This finding supports the idea that presenilins may play a role in the development and progression of Alzheimer's disease.

Another study by our laboratory has shown that presenilin 2 (P2) levels are decreased in the brains of individuals with Parkinson's disease, a neurodegenerative disorder. This finding suggests that presenilins may be a potential biomarker for Parkinson's disease and may have utility as a therapeutic target.

Potential Therapeutic Strategies

The identification of presenilins as potential drug targets and biomarkers has significant implications for the development of therapeutic strategies for neurodegenerative disorders. Several strategies have been proposed to target presenilins and improve neuronal function, including:

1. Small molecule inhibitors: Several studies have shown that the natural product PQ-1655 and other molecules can modulate the activity of presenilins, making them potential therapeutic targets. By inhibiting presenilin activity, these molecules may be able to protect against neurodegeneration and improve neuronal function.
2. RNA interference: RNA interference (RNAi) technology has been used to knockdown the expression of presenilin genes in animal models of neurodegenerative disorders. This approach may be a potential method to reduce presenilin levels and improve neuronal function in these disorders.
3. Targeted delivery: delivery of small molecules directly to the site of action may be an effective strategy to enhance the efficacy of therapeutic interventions. This approach may be particularly useful for targeting presenilins, which are known to be internalized in the cell.

Conclusion

In conclusion, presenilins have been identified as potential drug targets and biomarkers for a variety of neurodegenerative disorders. The modulation of cellular signaling pathways by presenilins and their ability to protect against neurodegeneration make them intriguing targets for small molecules and RNAi technologies. Further research is needed to fully understand the mechanisms of presenilins and their potential as therapeutic targets
