Abstract | The change of immune capacity with aging was evaluated by measuring the peripheral blood lymphocyte subsets of 249 normal individuals. Double stained lymphocytes with monoclonal antibodies were analyzed by FACS flowcytometry. It was found that the number of lymphocytes and the proportion of pan T cells, suppressor/cytotoxic T cells (CD8+T), cytotoxic T cells and inducer T cells significantly decreased and the proportion of helper T cells significantly increased with aging individuals over 60 years old. The proportion of B cells and suppressor T cells did not significantly change with aging. We also found that the proportion of suppressor-inducer/naive T cells (CD45RA+CD4+T) decreased with aging and helper-inducer/memory T cells (CD45RO+CD4+T) tended to increase until the 50-59 age group and then decrease with aging in the older age groups. The proportion of NK cells, especially the weakest subset of NK cells (CD57+CD16-cells) significantly increased in aged individuals. |

B細胞やサプレッサーT細胞の比率には, 加齢の影響を認めなかった. サプレッサーインデューサー/ナイーブT細胞(CD45RA+CD4+T)の比率は加齢とともに減少を示し, ヘルパーインデューサー/メモリーT細胞(CD45RO+CD4+T)は50歳代までは増加傾向を, 以後加齢とともに逆に低下傾向を示した. NK細胞の坤率は高齢者において有意な増加を示し, 特にNK活性の最も弱いCD57+CD16-NK細胞で顕著であった. |
