The Claim

1,25-Dihydroxyvitamin D suppresses the expression of microRNA-155 in mouse and human macrophages exposed to bacterial lipopolysaccharide, leading to reduced inflammation through de-repression of the anti-inflammatory protein SOCS1.

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

A form of vitamin D can calm down overactive immune cells in the body by turning down a specific molecule that causes inflammation, which helps the body produce a protein that reduces swelling and irritation.

See the scientific wording

1,25-Dihydroxyvitamin D suppresses the expression of microRNA-155 in both mouse and human macrophages exposed to bacterial lipopolysaccharide, reducing inflammation by de-repressing the anti-inflammatory protein SOCS1.

What the research says

1 study

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

    Vitamin D helps calm down overactive immune cells by turning down a molecule called miR-155, which normally blocks a natural brake on inflammation called SOCS1. When vitamin D reduces miR-155, SOCS1 can work better to stop excessive inflammation.
