Abstract

It is well known that sleep disorders are harmful to people's health and performance, and growing evidence suggests that sleep deprivation (SD) can trigger neuroinflammation in the brain. The nucleotide‐binding domain and leucine‐rich repeat protein‐3 (NLRP 3) inflammasome is reported to be relevant to the neuroinflammation induced by SD, but the regulatory signaling that governs the NLRP 3 inflammasome in SD is still unknown. Meanwhile, whether the regulatory action of antidepressants in astrocytes could affect the neuroinflammation induced by SD also remains obscure. In this study, we were the first to discover that the antidepressant fluoxetine, a type of specific serotonin reuptake inhibitor widely used in clinical practice, could suppress the neuroinflammation and neuronal apoptosis induced by SD. The main findings from this study are as follows: (i) SD stimulated the expression of activated NLRP 3 inflammasomes and the maturation of IL‐1β/18 via suppressing the phosphorylation of STAT 3 in astrocytes; (ii) SD decreased the activation of AKT and stimulated the phosphorylation of GSK‐3β, which inhibited the phosphorylation of STAT 3; (iii) the NLRP 3 inflammasome expression stimulated by SD was partly mediated by the P2X7 receptor; (iv) an agonist of STAT 3 could significantly abolish the expression of NLRP 3 inflammasomes induced by an agonist of the P2X7 receptor in primary cultured astrocytes; (v) the administration of fluoxetine could reverse the stimulation of NLRP 3 inflammasome expression and function by SD through elevating the activation of STAT 3. In conclusion, our present research suggests the promising possibility that fluoxetine could ameliorate the neuronal impairment induced by SD. image

  • Fluoxetine inhibits SD-induced stimulation of the NLRP3 inflammasome by the AKT/STAT3 and ERK/STAT3 pathways in vivo, and SD triggers depressive-like behaviors by stimulating astrocytic P2X7Rs.

    “Furthermore, administration of fluoxetine effectively inhibits SD-induced stimulation of the NLRP3 inflammasome by the AKT/STAT3 and ERK/STAT3 pathways in vivo, and SD dramatically triggers depressive-like behaviors by stimulating astrocytic P2X 7 Rs. 41 , 155”

    The Discussion (p. 17) and Figure 8 (p. 26) support the claim that fluoxetine suppresses SD-induced astrocytic NLRP3 inflammasome activity through ERK1/2- and AKT-mediated STAT3 activation in mice. The paper also links astrocytic P2X7R to SD-induced inflammasome formation, but it does not report that SD triggers depressive-like behaviors through that receptor; the depression-like behavior mentioned in the Introduction (p. 6) concerns a different study.

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.
