Metabolism of [3H]serotonin in the marine mollusc, Aplysia californica

Brain Research

Abstract

The fate of serotonin was studied in several tissues of the marine mollusc, Aplysia californica. When isolated nervous tissue was bathed in [3H]serotonin, two radioactive derivatives were formed; both appeared to be sugar conjugates: the first, possibly of glucuronic acid, and the second, of a more complex sugar moiety. When [3H]serotonin was injected directly into cell bodies of identified neurons, both serotonergic and non-serotonergic, only the conjugate which behaved as the glucuronide was formed. [3H]Serotonin was also converted only to this substance during incubation with isolated heart, kidney and hemolymph. Metabolic activity of the blood resided within cellular elements. No evidence of oxidative deamination was found in any tissue. In contrast to serotonin, however, [3H]tryptamine was readily oxidized to indoleacetic acid by nervous tissue.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.
