hCAP18 Levels and Vitamin D Deficiency in Healthy Subjects
hCAP18 Levels and Vitamin D Deficiency in Healthy Subjects
Vitamin D deficiency (low levels of vitamin D in the blood) is a common problem. A recently
 discovered protein, called hCAP18, likely plays an important role in the immune system and
 may depend on adequate levels of vitamin D. It is not known what levels of vitamin D are
 needed to allow the body to make this protein. Nor is it known if giving vitamin D to people
 who are found to be deficient will help boost levels of hCAP18. This study aims to clarify
 the relationship between vitamin D levels and hCAP18.
