Primate biology limits how rodent vitamin D data applies to human fungal infections

This review examined whether vitamin D could help treat invasive fungal infections. The authors looked at data from rodent studies to see if results would apply to humans. They found that the biology of primates differs significantly from rodents. Specifically, the way vitamin D regulates immune responses in primates is different from what was seen in mice. Because of these species differences, findings from rodent models cannot be directly applied to human patients with fungal infections. The review highlights that a specific genetic element controlling vitamin D responses exists in primates but not in rodents. This biological constraint means that positive results in mice do not guarantee the same effect in humans. Safety concerns were not reported because the study relied on existing animal data rather than human trials. Readers should understand that this evidence is limited to preclinical models. There is no proof that vitamin D works for fungal infections in people based on this information. The main takeaway is that more human-specific research is needed before making treatment recommendations.
