Abstract

The question of how the neural and immune systems interact in host defense is important, integrating a system that senses the whole body with one that protects. Understanding the mechanisms and routes of control could produce novel and powerful ways of promoting and enhancing normal functions as well as preventing or treating abnormal functions. Fragmentation of biological research into specialities has resulted in some failures in recognizing and understanding interactions across different systems and this is most striking across immunology, hematology, and neuroscience. This reductionist approach does not allow understanding of the in vivo orchestrated response generated through integration of all systems. However, many factors make the understanding of multisystem cross-talk in response to a threat difficult, for instance the nervous and immune systems share communication molecules and receptors for a wide range of physiological signals. But, it is clear that physical, hard-wired connections exist between the two systems, with the key link involving sensory, unmyelinated nerve fibers (c fibers) containing the neuropeptide calcitonin gene-related peptide (CGRP), and modified macrophages, mast cells and other immune and host defense cells in various locations throughout the body. In this review we will therefore focus on the induction of CGRP and its key role in the neuroimmune axis.

  • Type II afferents express neuropeptides such as CGRP, which in somatic C-fibers modulates the activity of immune cells that proliferate after trauma.

    “Type II afferents express neuropeptides such as CGRP (37, 38, 54), which in somatic C-fibers (55) modulates the activity of immune cells that proliferate after trauma (56).”

    From Damage-evoked signals in cochlear neurons and supporting cells (2024) · cites this paper as [55]

    The “CGRP and immunity” section says CGRP is released from sensory C-fibers during trauma or injury and that C-fiber neuropeptides modulate immune responses. “CGRP release in vivo” also describes CGRP acting on nearby immune cells. Neither passage establishes that those immune cells proliferate after trauma. (LLM, conf=0.84)

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.
