The Claim
Exogenous L-lactate increases neutrophil H3K18 lactylation, RORα expression, and inflammatory cytokine production in mice and zebrafish, whereas exogenous D-lactate does not, demonstrating stereospecificity and biological relevance of lactate as a signaling molecule.
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.
L-lactate, but not D-lactate, triggers specific molecular changes in neutrophils of mice and zebrafish, including increased H3K18 lactylation, higher RORα expression, and greater production of inflammatory cytokines.
See the scientific wording
Exogenous L-lactate, but not D-lactate, increases neutrophil H3K18 lactylation, RORα expression, and inflammatory cytokine production in mice and zebrafish, demonstrating stereospecificity and biological relevance of lactate as a signaling molecule.
When L-lactate enters neutrophils, it attaches to a specific spot on histone proteins near the RORα gene, turning on that gene. The RORα protein then turns on other genes that make inflammatory signals, causing neutrophils to multiply and move into tissues to trigger inflammation. D-lactate cannot do this because its shape does not fit the biological machinery that recognizes lactate as a signal.
What the research says
1 studyThe study shows that when mice and zebrafish are sleep-deprived, their bodies make more of the natural form of lactate, which turns on inflammatory genes in immune cells — proving lactate isn’t just waste, but a signal. It doesn’t test the mirror-image version (D-lactate), but everything it found fits with the idea that only the natural form works.
