Scientists from the University of California, Los Angeles (UCLA) conducted a study of the role of various nutrients in the fight against infectious agents. It turned out that the vitamin a activates the immune system and protects against Mycobacterium tuberculosis. The study was able to establish the mechanism of action of vitamin. Substance together with a special gene confer immunity, reduce cholesterol in the tissues affected by TB, writes The Times of India.
Cholesterol is an important indicator for the development of TB. It is believed that this is one of the nutrients required for breeding bacteria. In the study, researchers compared the effectiveness of various vitamins and found that vitamin D and help the immune system in the fight against infectious agents and elevated cholesterol.
It should be noted that the effect of vitamin a depends strongly on the degree of activity of the NPC2 gene. Affected cells, the scientists write, can not cope with the infection, if gene expression is minimal. Will not help even a direct introduction of the vitamin in the fabric.
The plan of scientists to establish the response of the immune system to an inactive form of vitamin a (retinol). Possibly a derivative of retinol helps to destroy the bacteria and fight the disease.
