The Meeting of the International Society for Serotonin Research (ISSR) has been a historic and premier forum to highlight the cutting edge in serotonin research. Keeping in this tradition, the 2025 meeting of the ISSR, held in Vienna, Austria, showcased an exciting program of serotonin research.

These presentations advanced our understanding of the roles of serotonin in health and disease, in relation to behavior and exciting new serotonin-based treatments for disease. This Special Issue in ACS Chemical Neuroscience will be a collection of this work, bringing together important perspectives, critical reviews and original research.

To gain deeper insights into the evolving discourse surrounding this topic, we invite you to explore a selection of recent serotonin research published in ACS Chemical Neuroscience below.

Topics include, but are not limited to:

  • Tool development for monitoring serotonin in different biological systems
  • Serotonin receptors and autoreceptors
  • Serotonin pharmacology, understanding the mechanism of action of existing drugs and development of new ones
  • How serotonin underlies behavior
  • Serotonin circuits
  • Disease studies
  • Computational models
