The Claim
One night of total sleep deprivation in healthy young adults is associated with a significant reduction in TLR7 mRNA expression in peripheral blood mononuclear cells, with women maintaining higher post-deprivation expression levels than men after adjusting for age and BMI.
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, healthy young adults show lower levels of TLR7 mRNA in immune cells in their blood, and women have higher levels than men after accounting for age and body weight.
See the scientific wording
One night of total sleep deprivation in healthy young adults is associated with a significant reduction in TLR7 mRNA expression in peripheral blood mononuclear cells, with women maintaining higher post-deprivation expression levels than men after adjusting for age and BMI, suggesting sex-specific modulation of innate immune signaling pathways.
Without sleep, the body's internal clock disrupts the activity of immune genes in blood cells, causing TLR7 to become less active. Women retain more TLR7 activity than men because their second X chromosome provides extra copies of the gene that stay active, giving them a biological advantage in maintaining this immune signal.
What the research says
1 studyAfter one night without sleep, the study found that a key immune gene (TLR7) became less active in blood cells, and women kept higher activity levels than men—even when accounting for age and weight. This matches exactly what the claim says.
