When people get insufficient sleep, taking low-dose aspirin lowers specific inflammatory markers—CRP, IL-6, and certain monocytes—but does not reduce other inflammatory signals or improve health...
Mechanism
Synthesis from 1 study
Aspirin blocks two specific enzymes in immune cells, which stops them from making signals that cause IL-6 and CRP to rise. This only affects those two markers and does not change other inflammation signals or health outcomes.
Most probable mechanism
Aspirin enters the body and permanently disables two enzymes called COX-1 and COX-2 inside certain immune cells. This stops those cells from making signaling molecules that trigger inflammation. As a result, the cells produce less IL-6, which causes the liver to make less CRP. This effect only happens for these specific signals and does not change other inflammation pathways or health outcomes.
Acetylsalicylic acid is deacetylated to salicylate, which irreversibly acetylates cyclooxygenase-1 and cyclooxygenase-2 enzymes in monocytes
Inhibition of COX-1 and COX-2 reduces the conversion of arachidonic acid to prostaglandin H2, suppressing downstream pro-inflammatory eicosanoid synthesis
Reduced prostaglandin signaling decreases NF-κB activation and cytokine transcription in monocytes
Lower IL-6 production by monocytes reduces hepatic synthesis of C-reactive protein
