Immunological tolerance

Japanese: 免疫学的寛容 - めんえきがくてきかんよう(英語表記)immunological tolerance
Immunological tolerance
A state in which immune responsiveness is specifically reduced. In general, the body does not display an immune response to self-antigens. This state is called self-tolerance or natural tolerance. It is also possible to specifically reduce immune responses to foreign antigens (protein antigens and isogeneic histocompatibility antigens) using a variety of methods. This state is called acquired tolerance. FM Barnett believed that specific lymphocytes that come into contact with self-antigens during the fetal and neonatal periods disappear, and natural tolerance is established.

特異的に免疫応答性が低下している状態。一般に自己の抗原物質に対して生体は免疫応答を示さない。この状態は自己免疫寛容あるいは自然免疫寛容と呼ばれている。また外来抗原(タンパク質抗原や同系組織適合抗原)に対しても,さまざまな方法で免疫応答を特異的に低下させることができる。この状態は獲得免疫寛容と呼ばれている。F.M.バーネットは,胎生期~新生期に自己抗原に触れた特異的リンパ球は消滅して自然免疫寛容が成立すると考えた。
