Association for the Sciences of Chemoreception: Fostering Research and Understanding of the Chemical Senses in Health and Disease


The 43rd AChemS Annual Meeting hosted scientists from around the world to present their latest research findings on a myriad of topics around chemosensation.

GLENVIEW, ILLINOIS, USA, November 23, 2021 / – For 5 days in April (19-23), scientists from around the world came together virtually to present and discuss new information on the role of the senses chemicals in disease, nutrition, and social interactions in humans and animals. The 43rd Annual Meeting of AChemS hosted scientists from around the world to present their latest research findings on a myriad of topics around chemosensation, ranging from molecular mechanisms to cognitive processes and associated behaviors. Around the world, thousands of people each year experience loss or dysfunction of the chemical senses (olfaction (smell), taste (taste) and chemesthesia (touch, temperature, irritation)) resulting from head trauma, disease. sinuses, cancer and neurological disorders, such as stroke, multiple sclerosis and Alzheimer’s disease, among others. More recently, loss of smell and / or taste has emerged as a troubling symptom of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which has infected millions of people around the world. By providing a better understanding of the function of chemosensory systems, scientific and biomedical research is leading to improvements in the diagnosis and treatment of many disorders.

Additionally, along with clinicians and researchers, members of the AChemS community organized the first World Taste and Smell Day on September 14, 2021.

World Taste and Smell Day is a celebration of taste and smell intended to promote awareness, understanding and appreciation of these essential, but often overlooked, senses. This virtual event also served as both an interpersonal support forum and clinical resource for the many taste and / or smell dysfunctions caused by COVID-19 or other causes.

Highlights from this year’s event and information on next year’s World Smell & Taste Day can be found at or by contacting Kareen Kreeger at kkreeger @
