Frontiers in Cellular Neuroscience recently published a general commentary highlighting a study conducted in the laboratory of Dr. Weihong Lin, about G-protein βγ subunits in the olfactory organs of mice. According to the Frontiers website, "Commentaries call attention to papers of particular note - either published in Frontiers or in other journals." In their commentary, Tamara Boto and Esther Alcorta of the Scripps Research Institute and the University of Oviedo respectively, draw attention to the study led by Dr. Lin and her graduate student, Aaron Sathyanesan, which provides a much-needed comprehensive analysis of G-protein βγ expression patterns in the mouse main olfactory epithelium and the vomeronasal organ. The highlighted study uncovers many interesting expression patterns of the βγ subunits of G-proteins, which may lead to the discovery of novel signaling pathways in olfactory and vomeronasal sensory neurons.
