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.
The pituitary glands are made of the anterior lobe and posterior lobe. The anterior lobe produces and releases hormones. The posterior lobe does not produce hormones per seâthis is done by nerve cells in the hypothalamusâbut it does release them into the circulation.Hormones of the Pituitary Gland.The hormones of the pituitary gland send signals to other endocrine glands to stimulate or inhibit their own hormone production.he posterior lobe does not produce hormones per seâthis is done by nerve cells in the hypothalamusâbut it does release them into the circulation.
