Therapeutic potential of dopamine and serotonin in inflammation and cancer: Insights into immune regulation.

Abstract

Introduction: This review explores the significant roles of neurotransmitters, focusing on dopamine and serotonin, in inflammation and cancer. These neurotransmitters are vital for neural signaling and play crucial roles in various physiological and pathological processes.

Materials and methods: We conducted an extensive literature review, focusing on studies published between 2013 and 2024, using databases such as PubMed, Google Scholar, and Scopus. Studies were selected based on relevance to neurotransmitter synthesis, receptor function, and their involvement in diseases like cancer and neurodegenerative disorders. The key search terms included "dopamine", "serotonin", "inflammation", and "cancer".

Results: Dopamine and serotonin are synthesized intracellularly and function as pivotal signaling molecules within the central nervous system (CNS) and peripheral systems. Through their respective receptors, dopamine and serotonin influence immune responses and the functionality of various bodily systems. Dysregulation in their signaling pathways is associated with a range of cancers and imbalances within the immune system.

Discussion: The interplay between dopamine and serotonin systems extends beyond neural communication, significantly affecting immune responses and inflammation. Dopamine's role in modulating immune cell activity highlights its potential in treating inflammatory conditions and cancer. Similarly, serotonin's extensive physiological impact underscores the importance of targeting 5-HT pathways in various disorders. Future research should focus on developing therapeutic strategies that leverage these neurotransmitters' regulatory functions in both the CNS and peripheral systems.
