Conditional Vitamin D Receptor Deletion Induces Fungal and Archaeal Dysbiosis and Altered Metabolites.

ABSTRACT: A vitamin D receptor (VDR) deficiency leads to the dysbiosis of intestinal bacteria and is associated with various diseases, including cancer, infections, and inflammatory bowel disease. However, the impact of a VDR deficiency on fungi and archaea is unknown. We conditionally deleted the VDR in Paneth cells (VDR^ΔPC), intestinal epithelial cells (VDR^ΔIEC), or myeloid cells (VDR^ΔLyz) in mice and collected feces for shotgun metagenomic sequencing and untargeted metabolomics. We found that fungi were significantly altered in each knockout (KO) group compared to the VDR^Loxp control. The VDR^ΔLyz mice had the most altered fungi species (three depleted and seven enriched), followed by the VDR^ΔPC mice (six depleted and two enriched),
