The Claim
One night of total sleep deprivation has no significant effect on TLR9 mRNA expression in peripheral blood mononuclear cells of healthy young adults, and baseline sex differences in TLR9 mRNA expression are eliminated following sleep deprivation.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
After one night without sleep, the level of TLR9 mRNA in immune cells from the blood of healthy young adults does not change significantly, and any differences in TLR9 mRNA levels between males and females before sleep loss are no longer present after sleep deprivation.
See the scientific wording
One night of total sleep deprivation does not significantly alter TLR9 mRNA expression in peripheral blood mononuclear cells of healthy young adults, despite baseline sex differences in expression that disappear after sleep loss.
When a person stays awake all night, the body's internal clock gets disrupted, causing immune cells in the blood to adjust how much TLR9 gene they produce. This adjustment brings the gene activity in men and women to the same level, even though they started at different levels. The total amount of TLR9 gene activity doesn't go up or down overall — it just becomes equal between sexes.
What the research says
1 studyAfter one night without sleep, the study found that the usual difference in TLR9 gene activity between men and women went away, but the overall level of this gene activity didn’t change for anyone — which means sleep loss didn’t boost or lower it overall.
