Conducted by researchers of the study found that the immune system depends on what month the child was born. As it turned out, less susceptible to development of multiple sclerosis and other autoimmune diseases, children born in November, and the highest risk of the aforementioned diseases found in children who celebrate their birthday in may. The scientists explained that the whole reason the level of vitamin D. it Should be recalled that this vitamin is produced in the human body under the influence of sun rays. Studies conducted earlier have already established interconnection between the level of vitamin D during pregnancy and risk of multiple sclerosis in children.
A recent study, which was conducted by researchers from the University of London Queen Mary, aims to compare the blood samples from the umbilical cord 100 babies. The children were born in may and November 2009-2010 in London. Through the analysis the researchers wanted to determine the level of vitamin D, as well as someactivity T-cells - white blood cells that participate in immune reactions. Thanks to these cells the body detects and eliminates viruses and infections. But there are certain T-cells, which instead of protecting, they begin to expose attack the human body. In the process of development of the immune system malicious T-cells it is neutralized.
The analysis of the blood showed that those born in November of children vitamin D levels up to 20 percent more than in children who were born in may. In addition, the "may" children the number of malicious T-cells twice in "November". According to scientists, this is due to a larger number of patients with multiple sclerosis among people who were born in may. It should be noted that multiple sclerosis is an autoimmune disease, in which affected myelin sheath of the brain. Very often this disease affects people in the age group from 15 to 40 years, and its symptoms are blurred vision, depression, emotional instability, dysfunctional behavior and mental decline.
