An estimated 5-30% of the population suffers from one or more functional pain disorders affecting the pelvic organs. Unfortunately, existing treatment options offer little relief as these disorders are generally not associated with any underlying pathology and the mechanisms generating the heightened pain sensations are poorly understood. The focus of my lab is to study how the relationship between neurotrophic growth factors and pain-related channel expression and function drives the nociceptive tone of pelvic afferents relaying pain information from the affected area. Neurotrophic growth factors, including nerve growth factor (NGF), glial cell line-derived neurotrophic factor (GDNF), artemin and neurturin are expressed at high levels during embryonic and postnatal development and are essential for establishing proper sensory innervation of peripheral tissues. Injury or inflammation during these early developmental stages can cause permanent changes in sensory processing, resulting in enhanced behavioral and cellular responses to painful (noxious) stimuli. Mice that received intracolonic mustard oil application during early postnatal development have a prolonged period of developmentally-high growth factor expression in the colon. We hypothesize that this may underlie their significantly heightened response to colorectal distension as adults, as well as the observed increase in the percentage of colon-specific sensory neurons that express the transient receptor potential channel ankyrin 1 (TRPA1; Christianson et al., Pain, in press). We are currently investigating whether neonatal vaginal irritation or stress caused from maternal separation will produce a similar effect with the ultimate goal of identifying common mechanisms as potential targets for therapeutic intervention in the treatment of chronic pelvic pain.
