Both sympathetic and sensory denervation resulted in lower immunoreactivity against markers of proliferation and fibrosis, especially sensory denervation.In Experiment 2, surgical denervation before or after induction of endometriosis also decelerated the development of endometriosis, as manifested by significantly reduced lesion weight and extent of lesional fibrosis, along with improved hyperalgesia.In Experiment 3, NK1R activation by SP infusion accelerated lesional development, as evidenced by significantly increased lesional weight, more thorough progression of EMT, FMT, SMM, exaggerated lesional fibrosis and deteriorated hyperalgesia.
Tachykinin mRNA (TACR1/2) and protein (neurokinin 1 receptor [NK1R]) expression in both eutopic and ectopic endometrial tissue from patients with endometriosis and the correlation to peritoneal fluid TNFα were measured.
Aim of this study was, therefore, to examine the effect of a single nucleotide polymorphism (SNP) of the NK1R gene on the susceptibility for endometriosis and the disease free survival (DFS) after surgery for endometriosis.
