VITAMIN D or vitamin that can be obtained from food or produced by human skin exposed to sunlight, play an important role in improving the body's immune system.
The presence of vitamin D is very crucial for the body. Therefore, the weapon T cells of the body, the cells that attack and destroy bacteria and viruses that lodged in the body. Scientists at the University of Copenhagen have found that vitamin D was very important to activate the human immune system. Without vitamin D intake is sufficient, killer cells of the immune system (T cells) will not be able to react and fight serious infections in the body.
Well, that T cells can detect and kill foreign pathogens such as bacteria and viruses, the cells must be triggered first and then transformed from inactive cells and become dangerous killer cells are ready to find and destroy all the attackers.
The researchers found that T cells depend on vitamin D in the activation process. Thus, the body will be vulnerable if the deficiency of vitamin D in the blood. Researchers from the Department of International Health, Immunology and Microbiology Professor Carsten Geisler said, when dealing with T cells of foreign pathogens, these cells will be held device or antenna signal, known as the vitamin D receptor, which will search for vitamin D.
