An Introduction on the Old Age and the Aging of the Immune System
The immune system is vital for the well-being and general health of all individuals, especially elderly, while like other systems it undergoes several changes during aging. Aging influence not only the renewal potential of this system but also the elements of the cytokine network essential for communication between its different parts. It is therefore very necessary to acquire more knowledge on the effects of aging on this highly complex system. Although, there is a growing body of literature on this field, there are far more controversial and unresolved subjects in need of further research. The well-being, health of the old people, and possible restoration of the potential of this system rely largely on the valuable knowledge remained to be gained by further research on this subject.
