Medical Xpress reports that Vitamin D is crucial in human immune response to tuberculosis. The researchers "found that T-cells, which are white blood cells that play a central role in immunity, release a protein called interferon-gamma that triggers communication between cells and directs the infected immune cells to attack the invading tuberculosis bacteria. However, this activation requires sufficient levels of vitamin D to be effective."
This important finding stirs very mixed emotions in me. In childhood and adolescence I suffered repeated bouts of pulmonary tuberculosis, after which time I was advised by health professionals to avoid exposing my skin to sunshine in case it reawakened the dormant TB germs. Vitamin D is known as the 'sunshine vitamin'. Clearly, in the light of this research finding (published online today,Oct. 12, in the peer-reviewed journal, Science Translational Medicine) the advice that I was given was completely wrong, and since I followed that advice for a long time, it cannot but have compromised my health. More and more, researchers are reporting the many health benefits that vitamin D bestows on us, and the many disbenefits that are caused by inadequate levels of vitamin D.
