Which Of These Glands Produce A Hormone That Stimulates Cells In The Immune System?. For example a hypothalamic hormone called gonadotrophin releasing hormone (gnrh) stimulates the pituitary synthesis and release of gonadotrophins. Among the cell types in each pancreatic islet are the alpha cells, which produce the hormone glucagon, and the beta cells, which produce the hormone insulin.
