The good news is scientists believe that the aging process of the immune system is quite possible to reverse.
Australian scientists from the University of Biomedicine to them. Monash (BDI) conducted a study and identified factors affecting aging of the immune system. About it reported in a press release on MedicalXpress. It turned out that as a result of the decrease in the production of specific proteins, it undermines the function of stem cells in the composition of the thymus.
Thymus (thymus) is constantly producing all the variety of lymphocytes. T-lymphocytes are active agents of the immune system and fight infections in our body. However, the thymus is the organ that one of the first to react to the age and development function of T-lymphocytes decreases, which leads to a weakening of the immune system.
In the elderly dysfunction of the thymus leads to inefficient functioning of the immune system, and as a result increases the susceptibility to infections and cancer development. It turned out that the dysfunction of the thymus are the factors influencing the growth and differentiation of epithelial stem cells. Scientists have found that older people have decreased production of bone morphogenetic protein BMP4.
As a result, in the thymus there is a loss of Mature epithelial cells and reduced production of T-lymphocytes. The study authors stressed that these changes can be reversed and start new research to see whether we can develop a treatment aimed at the regeneration of epithelial cells of the thymus.
