Abstract

Cre-ating Ways to Serotonin

Highlights

  • Almost 50 years ago Dahlström and Fuxe discovered serotonergic neurons in the brainstem

  • For a cell type-selective manipulation, a “Cre driver mouse” is mated with another that has a gene with recognition sites for Cre

  • Inducible Cre activity, where we can turn on the Cre recombinase at defined ages of the mouse, is better

Summary

Introduction

Almost 50 years ago Dahlström and Fuxe discovered serotonergic neurons in the brainstem. A commentary on Inducible gene manipulations in serotonergic neurons. Studying circuitry with genetics often involves putting foreign proteins, e.g. Cre (cyclization recombination) site-specific DNA recombinase from bacteriophage P1, in specific cell types (Sauer, 2002; Dymecki and Kim, 2007; Gong et al, 2007).
