Herring bodies or neurosecretory bodies are structures found in the
neurosecretory terminals.[1]
Antidiuretic hormone (ADH) and oxytocin are both stored in Herring bodies, but are not stored simultaneously in the same Herring body.[2]
In addition, each Herring body also contains ATP and a type of
neurophysin. Neurophysins are binding proteins, of which there are two types: neurophysin I and neurophysin II, which bind to oxytocin and ADH, respectively. Neurophysin and its hormone become a complex considered a single protein and stored in the neurohypophysis. Upon stimulation by the hypothalamus, secretory granules release stored hormones into the bloodstream. Fibers from supraoptic nuclei are concerned with ADH secretion; paraventricular nuclei with oxytocin.[3]
This anatomical structure was first described by
Percy Theodore Herring
in 1908.
