Vitamin «de» enhances the immune response

U.S. study concluded that vitamin «de» may play a key role in the response of the immune system effectively against diseases such as tuberculosis.

This discovery leads to the grounds therapies against the disease, which kills 1.8 million people a year. The dark-skinned people are more susceptible to tuberculosis, and see some areas in Africa, the highest proportions of patients in the world.

The researchers say the increased sensitivity to Bacillus bacteria, may be part of them back to a proliferation of melanin in dark-skinned, a substance that protects the chromosome from ultraviolet radiation.

And by reducing the absorption of solar radiation, reduces melanin production also vitamin «de», as interpreted by those in charge of the study.

And produces the majority percentage of vitamin «de» natural interaction between ultraviolet radiation, and a cholesterol derivative usually found in the body.

The researchers studied the processes that allow the immune system to eliminate disease-causing agents, such as Bacillus bacteria that cause tuberculosis.

They found that the cells «T» responsible for the response of the immune system produces a protein known as interferon-mentioned allows the cells to communicate and launch an attack against the bacteria that cause TB. However, in order to ensure the effectiveness of the effect of interferon, should be the proportion of vitamin «de» enough, the researchers explained that in light of their findings.

The supervisor of research Robert Moudlin that «our discovery leads us to conjecture that an increase in the proportion of vitamin D by supplementation improves immune response».
