It has long been known that each person reacts differently to diseases depending on the strength of the immune system.. Scientists have proven that the effectiveness of the immune system depends on genetic factors.

The blood of 134 volunteers was taken for the experiments.. Each sample was infected with a bacterial or viral disease and the results of the work of monocytes (white blood cells) were monitored.. Then the level of gene expression was measured at the stages of early and late immune response..

Research has shown that there are more than a hundred genes that play a key role in response to autoimmune, inflammatory and oncological diseases.. In addition, metabolism and the rate of aging of the body depend on them..

Also, scientists were able to find out that not all genetic diseases will necessarily manifest themselves.. It turns out that genes do not cause disease, but only weaken the immune system to certain types of diseases, such as lupus and celiac disease.. Their manifestation is influenced exclusively by the environment, including the presence of pathogens..
