The Claim
Chronic moderate exercise in mice increases chromatin accessibility at regulatory regions of M2-associated genes (e.g., CD206, Mertk, Maml2) and decreases chromatin accessibility at regulatory regions of M1-associated genes (e.g., MMP12, Src, Hoxa13/Hottip), resulting in epigenetic reprogramming toward an anti-inflammatory macrophage phenotype.
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.
In mice, regular moderate exercise changes the accessibility of DNA regions that control anti-inflammatory and pro-inflammatory genes, leading to a shift in macrophage gene expression patterns toward an anti-inflammatory state.
See the scientific wording
Chronic moderate exercise in mice increases chromatin accessibility at regulatory regions of M2-associated genes (e.g., CD206, Mertk, Maml2) and decreases accessibility at M1-associated genes (e.g., MMP12, Src, Hoxa13/Hottip), suggesting epigenetic reprogramming toward an anti-inflammatory macrophage phenotype.
Regular moderate exercise improves the energy efficiency of immune cells in the bone marrow, causing them to burn fuel differently and produce less cellular stress. This change opens up specific parts of their DNA that control healing genes and closes off parts that control inflammation genes. As a result, these cells become more focused on repair and less likely to trigger harmful inflammation.
What the research says
1 studyStudy: Moderate exercise induces trained immunity in macrophages.
When mice exercise regularly, their immune cells change how they read their DNA—making it easier to turn on healing genes and harder to turn on inflammation genes. This helps them stay healthier and less inflamed.
