Role of peripheral nerve fibres in acute and chronic inflammation in arthritis

Pongratz, Georg, Straub, Rainer H.·2013·Nature Reviews Rheumatology

Abstract

The peripheral nervous system takes an active part in inflammatory processes by regulating effector cell function and reallocation of energy to the immune system. During acute inflammation, rapid neuronal reorganization and change of activity takes place. The hallmarks of this process are an increase in systemic sympathetic activity, a decrease in systemic parasympathetic activity and loss of sympathetic nerve fibres from sites of inflammation concomitant with increased innervation with sensory nerve fibres and increased sensory nerve fibre activity. On a systemic level, the increase in sympathetic activity (and decrease in parasympathetic activity) is necessary to provide enough energy to nourish the activated immune system. In locally inflamed tissue, the decrease in sympathetic nerve fibre density results in reduced anti-inflammatory signalling and, together with neuropeptides released from sensory nerve fibres, promotes local inflammation. In acute inflammation, this 'inflammatory configuration' of the peripheral nervous system favours the rapid clearance of antigenic threats. However, in chronic autoimmune inflammation, these changes of the peripheral nervous system lead to an unfavourable situation with ongoing energy reallocation and continuous local destruction. As an example of a chronic inflammatory condition, we discuss evidence for neuroimmune regulation in autoimmune arthritis with a focus on the sympathetic nervous system.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The sympathetic nervous system can have a disease-propagating role in animal models of arthritis.

    “This can also be the reason for a disease-propagating role of the SNS in animal models of arthritis (summarized in [116]).”
  • Local density of sympathetic nerve fibers is markedly reduced in inflamed tissue of different chronic inflammatory diseases and in secondary lymphoid organs of animals with chronic inflammatory diseases, which is a pro-inflammatory signal.

    “However, it was observed that local density of sympathetic nerve fibers is markedly reduced in inflamed tissue of different CIDs and in secondary lymphoid organs of animals with CIDs, which is a pro-inflammatory signal recently summarized [116].”
  • Sympathetic neurotransmitters can have anti-inflammatory effects on monocytes, macrophages, natural killer cells, neutrophils, and T helper type 1 lymphocytes via β2-adrenergic receptors.

    “Since sympathetic neurotransmitters can have anti-inflammatory effects on monocytes, macrophages, natural killer cells, neutrophils, and T helper type 1 lymphocytes via β2-adrenergic receptors, increased activity of the SNS might be favorable in local inflammation [116].”

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.
