TFF-peptides (formerly P domain peptides, trefoil factors) are typical secretory products of many mucous epithelial cells. TFF3 is also synthesized in the hypothalamus and has anxiolytic or anxiogenic activities when injected into the rat amygdala. Here we show by immunohistochemistry that TFF3 is localized to a distinct population of neurons of the human hypothalamic paraventricular and supraoptic nuclei. Generally, TFF3-positive cells are co-localized in oxytocin-producing cells and not in vasopressin-producing cells. Relatively large amounts of TFF3-but not TFF1 and TFF2-are present in the posterior lobe of the human pituitary, where it is probably released into the bloodstream. Furthermore, TFF3 was also detectable in human postmortem cerebrospinal fluid.

TFF-peptides (formerly P-domain peptides, trefoil factors) are typical secretory products of many mucous epithelial cells. TFF3 is also synthesized in oxytocinergic neurons in the paraventricular and supraoptic nuclei of the human hypothalamus. Here, TFF3 and oxytocin are shown to be co-localized within the same secretory vesicles in the neural (posterior) lobe of the procine pituitary by means of immunoelectron microscopy. Relatively large amounts of TFF3, but not TFF1 and TFF2, are present in the neural lobe of the porcine pituitary, where it is probably released into the bloodstream.
