How Vitamin D Fights Tuberculosis (1 of 2)

Caption

Mycobacterium tuberculosis (red) is hiding in human macrophages (blue and green) cultured in vitamin D deficient serum so it is not being efficiently killed by cathelicidin and other proteins. This image relates to a paper that appeared in the Oct. 12, 2011, issue of Science Translational Medicine, published by AAAS. The paper, by Dr. M. Fabri of the David Geffen School of Medicine at University of California, Los Angeles in Los Angeles, Calif., and colleagues, was titled, "Vitamin D is Required for IFN-gamma Mediated Antimicrobial Activity of Human Macrophages."
