The distinction between neuropeptide and peptide hormone has to do with the cell types that release and respond to the molecule; neuropeptides are secreted from neuronal cells (primarily neurons but also glia for some peptides) and signal to neighboring cells (primarily neurons).oth neuropeptides and peptide hormones are synthesized by the same sets of enzymes, which include prohormone convertases and carboxypeptidases that selectively cleave the peptide precursor at specific processing sites to generate the bioactive peptides.
Parathyroid hormone (PTH), also known as parathormone, is a hormone released by the parathyroid glands. The four parathyroid glands are located in your neck, next to the thyroid gland.These glands are responsible for managing calcium, vitamin D, and phosphorus levels in the blood and bones.hus, calcium imbalances in the blood may be a sign of parathyroid gland or PTH issues. Calcium levels in the blood signal the parathyroid glands to release PTH. When calcium levels are low, the parathyroid glands increase PTH production.
