BACKGROUND AND PURPOSE Endometriosis is a disorder in which the endometrium forms growths outside the uterus and is associated with chronic pain. Recent evidence suggests that endometrial motility plays a role in the aetiology of endometriosis. The endocannabinoid system regulates cellular migration. Given the growing involvement of the endocannabinoids in(More)
Microglia provide continuous immune surveillance of the CNS and upon activation rapidly change phenotype to express receptors that respond to chemoattractants during CNS damage or infection. These activated microglia undergo directed migration towards affected tissue. Importantly, the molecular species of chemoattractant encountered determines if microglia(More)
The discovery of the endogenous cannabimimetic lipid mediators, anandamide and 2-arachidonoyl glycerol, opened the door to the discovery of other endogenous lipid mediators similar in structure and function. The majority of these compounds do not bind appreciably to known cannabinoid receptors; yet some of them produce cannabimimetic effects while others(More)
Response properties of peripheral afferent fibers supplying the vagina and uterus of the rat vary with estrous stage (Robbins A, Berkley KJ, Sato Y. Estrous cycle variation of afferent fibers supplying reproductive organs in the female rat. Brain Res 1992,596:353-356), suggesting that behavioral sensitivity to vaginal and uterine stimulation might similarly(More)
Cisplatin, a platinum-derived chemotherapeutic agent, produces mechanical and coldallodynia reminiscent of chemotherapy-induced neuropathy in humans. The endocannabinoid system represents a novel target for analgesic drug development. The endocannabinoid signaling system consists of endocannabinoids (e.g. anandamide (AEA) and 2-arachidonoylglycerol (2-AG)),(More)
The ability to sense changes in the environment is essential for survival because it permits responses such as withdrawal from noxious stimuli and regulation of body temperature. Keratinocytes, which occupy much of the skin epidermis, are situated at the interface between the external environment and the body's internal milieu, and have long been(More)
This study examined whether a rat model of surgically-induced endometriosis that reduces fertility also evokes vaginal hyperalgesia along with changes in vaginal compliance. In nine rats trained to escape vaginal distention, percent escape responses to different volumes of vaginal distention were measured for 2.5 months before and after endometriosis or(More)
UNLABELLED BACKGROUND Neurons are known to employ the endogenous cannabinoid system to communicate with other cells of the CNS. Endocannabioid signaling recruits microglia toward neurons by engaging cannabinoid CB2 and abnormal cannabidiol (Abn-CBD) receptors. The Abn-CBD receptor is a prominent atypical cannabinoid receptor that had been discriminated(More)
N-arachidonoyl glycine (NAGly) is an endogenous signaling lipid with a wide variety of biological activity whose biosynthesis is poorly understood. Two primary biosynthetic pathways have been proposed. One suggests that NAGly is formed via an enzymatically regulated conjugation of arachidonic acid (AA) and glycine. The other suggests that NAGly is an(More)
BACKGROUND Endocannabinoids may participate in the homeostasis of arterial pressure. Recently, anandamide, the most extensively studied endocannabinoid, has been proposed as a key mediator in the peripheral arterial vasodilation of cirrhosis. OBJECTIVES To determine if circulating levels of anandamide are related to the extent of the peripheral arterial(More)
