BACKGROUND Uterine natural killer (uNK) cells are the most abundant leukocytes in pre-implantation endometrium and early pregnancy deciduas in humans and rodents. They are associated with structural changes in maternal spiral arteries but regulation of their recruitment and activation is incompletely understood. The major subpopulation of uNK cells in humans expresses CD56, the neural cell adhe...

tooth pulpal nerves include sympathetic and sensory nerves that originate from trigeminal ganglion .from the terminal of these sensory nerves neuropeptides are secreted that are neuromodulators and neurotransmitters. one of them is cgrp (calcitonin gene-related protein) which has a vasodilatory effect on pulpal vessels. near abscess and moderate injuries, this neuropeptide can lead to neural fi...
