Stress induces a switch of intracellular signaling in sensory neurons in a model of generalized pain - Source: The Journal of Neuroscience, May 28, 2008

Stress dramatically exacerbates pain in diseases such as Fibromyalgia and rheumatoid arthritis, but the underlying mechanisms are unknown.

We tested the hypothesis that stress causes generalized hyperalgesia [increased sensitivity to pain] by enhancing pronociceptive [pain promoting] effects of immune mediators [signaling molecules].

Rats exposed to nonhabituating sound stress exhibited no change in mechanical nociceptive threshold, but showed a marked increase in hyperalgesia evoked by local injections of prostaglandin E(2) or epinephrine.

This enhancement, which developed more than a week after exposure to stress, required concerted action of glucocorticoids and catecholamines at receptors located in the periphery on sensory afferents.

The altered response to pronociceptive mediators involved a switch in coupling of their receptors from predominantly stimulatory to inhibitory G-proteins (G(s) to G(i)), and for prostaglandin E(2), emergence of novel dependence on protein kinase C epsilon.

Thus, an important mechanism in generalized pain syndromes may be stress-induced coactivation of the hypothalamo-pituitary-adrenal and sympathoadrenal axes, causing a long-lasting alteration in intracellular signaling pathways, enabling normally innocuous levels of immune mediators to produce chronic hyperalgesia.
