The imbalance of circulating pro-inflammatory cytokines interleukin-12 and interferon gamma and anti-inflammatory cytokine interleukin-1ra in chronic insomnia disorder.

A growing body of literature suggests that cytokines can play an important role in chronic insomnia disorder (CID); however, the underlying mechanisms are still unknown. Here we show that serum levels of pro-inflammatory mediators including IL-12, IFN-γ and ICAM-1 are elevated in CID group when compared with healthy controls, and that the REM sleep duration diminishes with increased concentrations of IL-12 and IFN-γ in individuals with CID. Furthermore, we find that lowered serum concentration of IL-1ra is negatively correlated with severity of insomnia in CID group.

Natural Immunosuppressants as a Treatment for Chronic Insomnia Targeting the Inflammatory Response Induced by NLRP3/caspase-1/IL-1β Axis Activation: A Scooping Review.

Chronic insomnia is an inflammatory-related disease with an important pathological basis for various diseases which is a serious threat to a person's physical and mental health. So far, many hypotheses have been proposed to explain the pathogenesis of insomnia, among which inflammatory mechanisms have become the focus of scientific attention. In this regard, the aim of the present scooping review is to evaluate the potential benefits of natural compounds in treatment of chronic insomnia targeting nucleotide-binding oligomerization domain (NOD)-like receptor-pyrin-containing protein 3 (NLRP3)/caspase-1/IL-1β axis as one of the most important activators of inflammatory cascades.

Interleukin-1α and tumor necrosis factor α as an inducer for reactive-oxygen-species-mediated NOD-like receptor protein 1/NOD-like receptor protein 3 inflammasome activation in mononuclear blood cells from individuals with chronic insomnia disorder.

Background And Purpose: There is some evidence that cytokines may play an important role in sleep deprivation; however, the underlying mechanisms are still unknown. So, the present study aimed to evaluate the relationship between NOD-like receptor protein 1 (NLRP1) and NOD-like receptor protein 3 (NLRP3) inflammasome activation of blood cells and serum levels of cytokines in individuals with chronic insomnia disorder (CID).

Methods: Blood samples were collected from 24 individuals with CID and 24 healthy volunteers.

IgLON5 autoimmunity tested positive in patients with isolated chronic insomnia disease.

In the patients with neurological autoimmune diseases such as anti-IgLON5 disease, insomnia symptoms are very common. Clinical diagnosis of the anti-IgLON5 disease is usually made when neurodegenerative processes have occurred. To find the early signs of anti-IgLON5 disease, we evaluate the presence of IgLON5 autoantibodies in the serum of patients with chronic insomnia disease.
