Pineal Histology

  • Pinealocytes - produce and secrete melatonin.
  • Astrocytes - glial cells (contain glial fibrillary acidic protein, GFAP) may play a role in modulation of pineal indoleamines and norepinephrine.
    • Human and sheep astrocytes - form arrangements of processes around the pinealocytes (sheep form a specialised "basket-like" arrangement). Fibres in human and sheep pineals may be derived from both intra- and extra glandular sites. Fibre arrangement and origins differ for rodents. PMID 3897467
