Abstract

Abstract. Bruchfeld A, Goldstein RS, Chavan S, Patel NB, Rosas‐Ballina M, Kohn N, Qureshi AR, Tracey KJ. (Karolinska Institute, Stockholm, Sweden; The Feinstein Institute for Medical Research, North Shore University Hospital‐LIJ Health System, Manhasset, NY, USA; and Karolinska Institute, Stockholm, Sweden) Whole blood cytokine attenuation by cholinergic agonists ex vivo and relationship to vagus nerve activity in rheumatoid arthritis. J Intern Med 2010; 268:94–101. Objective. The central nervous system regulates innate immunity in part via the cholinergic anti‐inflammatory pathway, a neural circuit that transmits signals in the vagus nerve that suppress pro‐inflammatory cytokine production by an α‐7 nicotinic acetylcholine receptors (α7nAChR) dependent mechanism. Vagus nerve activity is significantly suppressed in patients with autoimmune diseases, including rheumatoid arthritis (RA). It has been suggested that stimulating the cholinergic anti‐inflammatory pathway may be beneficial to patients, but it remains theoretically possible that chronic deficiencies in this pathway will render these approaches ineffective. Methods. Here we addressed the hypothesis that inflammatory cells from RA patients can respond to cholinergic agonists with reduced cytokine production in the setting of reduced vagus nerve activity. Results. Measurement of RR interval variability (heart rate variability, HRV), in RA patients (n = 13) and healthy controls (n = 10) revealed that vagus nerve activity was significantly depressed in patients. Whole blood cultures stimulated by exposure to endotoxin produced significantly less tumour necrosis factor in samples from RA patients as compared to healthy controls. Addition of cholinergic agonists (nicotine and GTS‐21) to the stimulated whole blood cultures however significantly suppressed cytokine production to a similar extent in patients and healthy controls. Conclusion. These findings suggest that it is possible to pharmacologically target the α7nAChR dependent control of cytokine release in RA patients with suppressed vagus nerve activity. As α7nAChR agonists ameliorate the clinical course of collagen induced arthritis in animals, it may be possible in the future to explore whether α7nAChR agonists can improve clinical activity in RA patients.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
