Description

Insulin-like 6 immunoreactivity (irINSL6) was detected in Leydig cells of the mouse testis. In the brain, labeled somata were detected mainly in the caudal hypothalamus and midbrain. Double labeling the brainstem sections revealed that irINSL6 somata were 5-hydroxytryptamine (5-HT) positive. The presence of irINSL6 in discrete populations of hypothalamic and brainstem neurons and in Leydig cells of the testis suggests a diverse biological function of this novel peptide.
