Telomere shortening in leukocyte subpopulations in depression

Telomere shortening is a normal age-related process. However, premature shortening of telomeres in leukocytes--as has been reported in depression--may increase the risk for age-related diseases. While previous studies investigated telomere length in peripheral blood mononuclear cells (PBMCs) as a whole, this study investigated specific changes in the clonal composition of white blood cells of the adaptive immune system (CD4+ helper and CD8+...
