Brain and gut peptides {bombesin} can lower body temperature, control gastric secretions, and stimulate appetite.
Intestinal hormones {peptide YY3-36} (PYY) can work in hypothalamus to reduce appetite.
Gut, hypothalamus, medulla-oblongata, pons, substantia-nigra, and spinal-cord dorsal-root peptides {substance P}| (SP) can be in fine pain fibers and affect peripheral sympathetic catecholamine neurons. Substance P releases serotonin from terminals inhibited by serotonin. Substance P makes long lasting excitation by slow, excitatory postsynaptic potentials and can cause pain. Substance P increases preprotachykinin mRNA. Sympathetic-neuron activity suppresses substance P. Serotonin enhances substance-P release to excite spinal cord.
Gut, cerebral-cortex bipolar-cell, and submandibular salivary-gland postsynaptic parasympathetic-neuron peptides {vasoactive intestinal peptide}| (VIP) can regulate neuronal mitosis, process outgrowth, and sympathetic-neuron survival.
