The number and percentage of T cell subsets change with ageing. a; c Subjects were divided into 3 groups according to three distinct T cell phases: memory generation (ages: 0–20 years, n = 19), memory homeostasis (ages: 20–60 years, n = 41), and immunosenescence (ages:over 60 years, n = 32). a The overall lengths of the bars indicate the absolute median count of the CD4 populations in the three phases according to our data. The different parts of each bar represent different T cell subsets, and the median percentage of each population is written in their respective position. b Schematic diagram of the ageing contribution to the decrease in T cells and thymic stromal cells and increase in adipocyte in the thymus. This process was accompanied by the accumulation of CD28- and CD95+ T cells in the peripheral blood. c The overall lengths of the bars indicate the absolute median count of CD8 populations in three phases according to our data. The different parts of each bar represent different T cell subsets, and the median percentage of each population is shown in their respective positions
