Inhibition of enzymes involved in adenosine degradation potentiated the acupuncture-elicited increase in adenosine, as well as its anti-nociceptive effect. This impressive paper is the first set of studies to identify a critical role for adenosine in the local mechanism of manual acupuncture in inflammatory and.

Adenosine A1 receptors mediate local anti-nociceptive effects of acupuncture.

New Finding Interesting Hypothesis. Worse, her speculations would also have been easy enough to test, given that she had the experimental model up and apparently running smoothly. Consider the following examples, but note that this is not an exhaustive list:. However, this effect differs from the anti-nociceptive effect of acupuncture, which does not depend on the afferent innervation of the skin.

Up until now, this paper was a fairly straightforward neuroscience paper looking at some interesting results. Scientists could take these observations and use them as the scientific justification to work on better, more specific, and longer acting A1 agonists.

Injecting CCPA into the Zusanli point greatly improved touch sensitivity and in essence reversed the increased sensitivity to heat. Don’t have an account? You have a close personal relationship e.

Having established that adenosine was increased within 30 minutes of an acupuncture stimulus, Nedergaard then injected an chemical that binds to the cell receptor activated by adenosine, the A1 receptor agonist, 2-chloro-N 6 -cyclopentyladenosine CCPA.

As in acupuncture, adenosine may accumulate during these treatments and dampen pain in part by the activation of A1 receptors on sensory locl of ascending nerve tracks. The tissue damage, virtually no matter where the needle is stuck, is going to be close to these nerves.

All Figure S3 shows is that failing to rotate the needle results in loss of the analgesic effect.

Citations Publications citing this anti-nocifeptive. Does that mean that Christian Science prayer is an effective treatment for anything? In the current study, scientists found that the chemical is also very active in deeper tissues affected by acupuncture. For instance, the kidney, stomach, and spleen acupuncture points line anti-nocixeptive somewhat with nerves at certain points in the body but are nowhere near ascending nerves in other parts.

This latter indication corresponds to the concept that needling this point can tonify the sea of qi and thereby help to stop the wasting disease and restore ones body weight and vitality. Perturbations in mitochondrial dynamics induced by human mutant Anti-nocicetpive can be rescued by the mitochondrial division inhibitor mdivi As Steve Novella has pointed out, in general in medicine at least these daysthe trajectory of research is usually from bench research to animal models to small scale, less rigorous, pilot studies in humans to large scale, rigorously designed studies using many subjects.


Adenosine A1 receptors mediate local anti-nociceptive effects of acupuncture.

McAlonan Evidence-based complementary and alternative…. However, it is possible that ATP release from keratinocytes in response to mechanical stimulation of the skin results in an accumulation of adenosine that transiently reduces pain, as A1 receptors are probably expressed by nociceptive axon terminal in epidermis. Robert Brett Kelly American family physician These observations indicate that adenosine mediates the effects of acupuncture and that interfering with adenosine metabolism may prolong the clinical benefit of acupuncture.

You work at the same institute as any of the authors. From This Paper Topics from this paper. AcupunctureScience and the Media Tagged in: The current standard indications for zusanli, as reviewed in Advanced Textbook of Traditional Chinese Medicine and Pharmacology 21 are: The Zusanli point in a mouse is going to be within a couple of millimeters of the sciatic nerve or one of its major branches.

Apparently in the mouse adenosine has a lot to do with modulating pain response in peripheral nerves, and apparently a fair number of pharmaceutical companies are interested in developing adenosine agonists to take advantage of this effect in humans. Posted by David Gorski Dr. Perhaps they could even develop oral drugs that are broken down into adenosine or A1 receptor agonists in the peripheral tissues.

Even better, this effect was not observed in mice genetically engineered not to make the adenosine A1 receptor, known as A1 receptor knockout mice, strong evidence that it was the A1 receptor that was responsible for the observed blunting of the pain response.
