日本の内藤メディカルクリニックに高齢化などの免疫活性試験に関する参考文献として、結論は免疫細胞の活動は二十代後の経時につれて減少しているです。

 

他の研究で調べてみると、

Age-related effects on Immune Cells; NK, NKT, mast cells and eosinophils

 

Cell type Change with advanced age Change
NK cells numbers in circulation ↑ increase
activity ↓ decrease
cytotoxicity ↓ decrease
Intact ADCC
proliferation and IFN-γ production in response to IL-2 ↓ decrease
NKT cells numbers in lymphoid organs and blood ↑ increase
Contribute to age-associated:
in vitro T cell proliferation ↓ decrease
in vivo DTH ↓ decrease
IL-10 and IL-4 ↑ increase
cytotoxicity ↓ decrease
Mast cells numbers in the skin of humans ↓ decrease
numbers in the skin of BALB/c mice; no change in C57BL/6 mice ↑ increase
degranulation in varicose disease ↑ increase
Eosinophils cell number in sputum No change
release of EDN in response to IL-5 in asthma patients ↓ decrease
release of EDN in response to fMLP ↓ decrease
production of O2- in response to PMA ↓ decrease
adhesion or chemotaxis in asthma patients No change
