Described herein are methods, devices and systems for inhibition of granulocyte activation by appropriate stimulation of the vagus nerve. Methods of treating granulocyte-mediated disorders (including inflammatory disorders) by stimulating the vagus nerve to inhibit granulocyte activation (particularly neutrophil activation) are also described. Appropriate stimulation may be very low levels of stimulation, including stimulation that does not result in desensitization. The level of granulocyte activation may be detected and used to at least partially control stimulation.

1. A method of treating and/or preventing a granulocyte-mediated disease or disorder in a subject, the method comprising: detecting a granulocyte activation level; andstimulating the subject's inflammatory reflex in an amount sufficient to achieve an inhibition in expression of a marker of granulocyte activation without desensitizing the response of the subject's granulocytes to vagal stimulation. 2. The method of claim 1, further comprising stimulating the subject's inflammatory reflex to achieve a sustained reduction of expression of the marker of granulocyte activation. 3. The method of claim 1, further comprising stimulating the subject's inflammatory reflex to achieve a reduction of expression of the marker of granulocyte activation without substantially reducing the expression of CD16b. 4. The method of claim 1, wherein the marker of granulocyte activation is CD11b expression. 5. The method of claim 1, wherein the granulocytes affected by stimulation of the inflammatory reflex are neutrophils. 6. The method of claim 1, wherein the granulocyte-mediated disease or disorder granulocyte is selected from the group consisting of: diabetes, atherosclerosis, cancer, septic shock, acute respiratory distress syndrome (ARDS), bacterial meningitis, acute pancreatitis, multiple organ failure (MOF), post-ischemic reperfusion, acute cellulitis, abdominal aortic aneurysm, asthma, osteomyelitis, Crohn's disease, cystic fibrosis, emphysema, septic or bacterial pyelonephritis, rheumatoid arthritis, septic arthritis, uveitis, periodontitis, psoriasis, severe burns, skin ulceration, acute lung injury, pneumonia, trauma, severe early graft dysfunction, brochioeactasis, chronic obstructive pulmonary disease (COPD), complications with hemodialysis, hypersensitivity pneumonitis, lung fibrosis, herpes stromal keratitis, vascular restenosis, glomerulonephritis, hypersensitivity, cardiac rupture arising as a complication with myocardial infarction, multiple sclerosis, stroke or cerebral ischemia, and traumatic brain injury. 7. The method of claim 1, wherein the inflammatory reflex is stimulated by electrical stimulation. 8. The method of claim 1, wherein the inflammatory reflex is stimulated by mechanical stimulation. 9. The method of claim 1, wherein the inflammatory reflex is stimulated by electromagnetic stimulation. 10. The method of claim 1, wherein the stimulation comprises extremely low frequency, low level stimulation. 11. The method of claim 1, further comprising implanting a stimulator for stimulating the inflammatory reflex. 12. The method of claim 1, further comprising determining if the subject is a candidate for inhibition of granulocyte-mediated disease or disorder by stimulation of the inflammatory reflex. 13. The method of claim 1, wherein the step of stimulating the inflammatory reflex comprises stimulating the vagus nerve. 14. A method of treating and/or preventing a granulocyte-mediated disease or disorder in a subject, the method comprising: stimulating the subject's vagus nerve in an amount sufficient to inhibit the expression of CD11b on the surface of the subject's granulocyte cells without desensitizing the response of the granulocytes to vagal stimulation; andscreening the subject at different times to determine the extent of inhibition of granulocyte activation in response to vagal stimulation. 15. The method of claim 14, wherein the stimulation of the subject's vagus nerve is sufficient to inhibit CD11b expression for a period of greater than 12 hours. 16. The method of claim 14, wherein the disease or disorder is selected from the group consisting of: diabetes, atherosclerosis, cancer, septic shock, acute respiratory distress syndrome (ARDS), bacterial meningitis, acute pancreatitis, multiple organ failure (MOF), post-ischemic reperfusion, acute cellulitis, abdominal aortic aneurysm, asthma, osteomyelitis, Crohn's disease, cystic fibrosis, emphysema, septic or bacterial pyelonephritis, rheumatoid arthritis, septic arthritis, uveitis, periodontitis, psoriasis, severe burns, skin ulceration, acute lung injury, pneumonia, trauma, severe early graft dysfunction, brochioeactasis, chronic obstructive pulmonary disease (COPD), complications with hemodialysis, hypersensitivity pneumonitis, lung fibrosis, herpes stromal keratitis, vascular restenosis, glomerulonephritis, hypersensitivity, cardiac rupture arising as a complication with myocardial infarction, multiple sclerosis, stroke or cerebral ischemia, and traumatic brain injury. 17. The method of claim 14, wherein the stimulation is mechanical stimulation, electrical stimulation, or electromagnetic stimulation. 18. The method of claim 14, wherein the stimulation comprises pressure applied to the subject's vagus nerve. 19. The method of claim 14, wherein the stimulation comprises extremely low frequency, low level stimulation. 20. The method of claim 14, further comprising implanting a stimulator configured to apply stimulation to the subject's vagus nerve. 21. A method of treating and/or preventing a granulocyte-mediated disease or disorder in a subject, the method comprising: detecting a baseline granulocyte activation level; andapplying a first stimulation to the subject's inflammatory reflex to inhibit granulocyte activation in response to the detected granulocyte activation level. 22. The method of claim 21, wherein the step of applying stimulation to the subject's inflammatory reflex comprises stimulating the subject's vagus nerve. 23. The method of claim 21, further comprising: detecting a second granulocyte activation level after a predetermined time after applying the first stimulation to the subject's inflammatory reflex;comparing the second granulocyte activation level with the baseline granulocyte activation level to determine a level of inhibition; andapplying a second stimulation to the subject's inflammatory reflex when the level of inhibition exceeds a predetermined threshold. 24. The method of claim 21, wherein the step of detecting a granulocyte activation level comprises detecting expression of CD11b expression on granulocytes. 25. The method of claim 21, wherein the stimulation comprises mechanical stimulation. 26. The method of claim 21, wherein the stimulation comprises electrical stimulation. 27. The method of claim 21, wherein the stimulation comprises electromagnetic stimulation.
