title: [Peptide modulation in vascular headache].
abstract: This article reviews recent developments in the field of vasoactive peptides in relation to certain types of headache. The equilibrium existing in the brain between contraction and dilatation of blood vessels is controlled by, among other factors, vasoactive peptides. Several of these have been discovered only recently and constitute a rapidly expanding field of research with exciting perspectives. Cranial blood vessels are innervated by sympathetic, parasympathetic and sensory nerve fibres, all of which contain certain vasoactive peptides as co-transmitters. Others, like endothelin, can be produced by the endothelium. There is evidence to suggest that vasoactive peptides of the trigeminovascular system are liberated in response to abnormal constriction of cranial blood vessels and contribute to headache. New drug therapies based on the activity of such substances are now being developed.
