The Claim

1,25-dihydroxyvitamin D3 strongly up-regulates the human cathelicidin antimicrobial peptide (CAMP) gene in myeloid cells, including acute myeloid leukemia cell lines, immortalized keratinocytes, colon cancer cells, and normal human bone marrow-derived macrophages, through binding to a vitamin D response element in the CAMP promoter, revealing a direct molecular mechanism linking vitamin D to innate immune regulation in primates.

Source: Human cathelicidin antimicrobial peptide (CAMP) gene is a direct target of the vitamin D receptor and is strongly up‐regulated in myeloid cells by 1,25‐dihydroxyvitamin D3

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.

How it works
1 study reviewed
In plain English

Vitamin D activates a gene in certain human immune cells that helps fight off germs, and this happens because vitamin D directly attaches to a specific spot on the gene to turn it on.

What the research says

1 study
  1. Study: Human cathelicidin antimicrobial peptide (CAMP) gene is a direct target of the vitamin D receptor and is strongly up‐regulated in myeloid cells by 1,25‐dihydroxyvitamin D3

    This study shows that a form of vitamin D turns on a human gene that helps fight germs, and it does so in immune cells exactly as claimed — by attaching to a specific spot on the gene’s DNA.
