A group of researchers from the University of Copenhagen has found that in order for the body's immune system to start up, it is imperative that there is an appropriate level of vitamin D in the blood, and that the T cells that are part of it can not Activate when there is not enough vitamin D because, as Professor Carsten Geisler of the Department of International Health, Immunology and Microbiology explains, before combating pathogens, T cells activate a receptor to obtain vitamin D and, if they do not get the necessary , they can not act.
T cells have the function of combating external pathogens that attack the human body, such as bacteria, viruses, and certain toxic substances. In order to carry out their mission, they join the invading pathogens and multiply in order to destroy them. Once activated, these cells also have the possibility of storing the characteristics of the pathogens for their subsequent recognition by the immune system.
Although scientists already know the decisive role of vitamin D in processes such as the absorption of calcium, and in the prevention of diseases such as osteoporosis, cancer or multiple sclerosis, until now its important contribution to the functioning of the immune system was unknown. . In the opinion of Professor Geisler, this finding could contribute to fight against infections and global epidemics, and serve to develop new vaccines and in the treatment of autoimmune diseases.
