Neuropeptide Y, its localization in the human cervix and possible effect on the contractile activity of cervix smooth muscle.
Immunochemical methods were used to identify neuropeptide Y (NPY) in the cervical tissue of women at early and term pregnancy. NPY-containing fibers could not be demonstrated in the upper and lower uterine segments at term, but the cervical innervation persisted during labor. Moreover, NPY alone did not affect cervical contractile activity, although the stimulatory effect of noradrenaline was enhanced.
