The Claim

Deletion of microRNA-155 in mice reduces the hyperinflammatory response induced by vitamin D receptor deficiency, indicating that overexpression of microRNA-155 is necessary for the exaggerated inflammation observed in vitamin D-deficient macrophages.

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.

How it works
1 study reviewed
In plain English

When scientists removed a tiny gene regulator called miR-155 from mice that lacked vitamin D receptors, the mice’s immune systems didn’t go into overdrive anymore. This suggests that too much of this gene regulator is what makes the inflammation worse when vitamin D is low.

See the scientific wording

Deletion of microRNA-155 in mice attenuates the hyperinflammatory response caused by vitamin D receptor deficiency, demonstrating that miR-155 overexpression is necessary for the exaggerated inflammation seen in vitamin D-deficient macrophages.

What the research says

  1. Study: 1,25-Dihydroxyvitamin D Promotes Negative Feedback Regulation of TLR Signaling via Targeting MicroRNA-155–SOCS1 in Macrophages

    When mice don’t have enough vitamin D signaling, their immune cells go into overdrive because a tiny molecule called miR-155 gets too active. When scientists removed miR-155, the overactive inflammation stopped — proving miR-155 is the culprit.
