Abstract:
Psychiatric disorders rank among the most common severe diseases worldwide, with millions of people affected worldwide every year. The symptoms are manifold, and the outcome for the patients is often unclear. As a high and yearly rising cost burden for society, anxiety disorders, depression and their related mental disorders are currently a well-researched topic in order to develop new functional pharmacological therapies as alternatives to those that are in use and bear many unpleasant side effects. Brain circuitries, such as those underlying anxiety formations, are mainly driven by the interplay of various neurotransmitter systems and the interaction of different brain loci, as well as the modulating impact of neuropeptides. Targeting those networks is a complex but promising way to regulate mood. Alterations on molecular level of the neuronal cell in response to respective receptor activation, especially at post-transcriptional level via the highly regulatory function of non-coding RNAs such as microRNAs (miRNAs) seem to hold a promising future in the development of novel therapeutic strategies and are therefore under intensified investigation. This review focusses on the impact of miRNAs on the neurotransmitter and neuropeptide systems of the central nervous system relevant for the formation of anxiety disorders and discusses the potential of miRNAs for the development of new therapeutic strategies for anxiety and mood disorders.
Insights
MicroRNAs (miRNAs) show promise for treating anxiety and mood disorders by regulating neurotransmitter and neuropeptide systems. This review explores their impact on brain circuitry and potential as novel therapeutic targets.
Area of Science:
- Neuroscience
- Molecular Biology
- Psychiatry
Background:
- Psychiatric disorders, including anxiety and depression, are a significant global health burden with unclear patient outcomes.
- Current treatments for mental disorders have limitations and unpleasant side effects.
- Brain circuitry, neurotransmitter systems, and neuropeptides are key to mood regulation and anxiety formation.
Purpose of the Study:
- To review the impact of microRNAs (miRNAs) on neurotransmitter and neuropeptide systems in the central nervous system relevant to anxiety disorders.
- To discuss the therapeutic potential of miRNAs for anxiety and mood disorders.
Main Methods:
- Literature review focusing on molecular mechanisms and neurobiology.
- Analysis of the role of non-coding RNAs, specifically miRNAs, in regulating neuronal function.
- Examination of miRNA interactions with neurotransmitter and neuropeptide systems.
Main Results:
- MicroRNAs (miRNAs) play a crucial role in post-transcriptional regulation of genes involved in neuronal signaling.
- Alterations in miRNA expression are linked to the molecular basis of anxiety and mood disorders.
- miRNAs modulate key neurotransmitter and neuropeptide systems implicated in mental health.
Conclusions:
- MicroRNAs represent a promising frontier for developing novel therapeutic strategies for psychiatric disorders.
- Targeting miRNA pathways offers a potential avenue for more effective and targeted treatments for anxiety and mood disorders.
- Further research into miRNA function is essential for translating these findings into clinical applications.
