- 自己免疫とは,自己免疫である.
- レウマトロジーの病理学
背景:
- リウマチ性関節炎 (RA) は,原因がよくわかっていない慢性関節疾患です.
- RAは白血球の侵入,シノビオサイトの活性化,そしてその後の軟骨/骨の破壊を伴う.
研究 の 目的:
- ヒトのリウマチ性関節炎を模倣する新しい自発的なマウスモデルを記述する.
- このモデルにおいて,関節疾患の発症の根本的なメカニズムを調査する.
主な方法:
- NOD株とT細胞受容体 (TCR) トランスジェニックラインを交差させ,マウスモデルの生成.
- 子孫における疾患発達の観察は,ヒトのRAを想起させる関節疾患として特徴付けられています.
主要な成果:
- すべての子孫は,ヒトのRAに似た関節疾患を発症した.
- トリガーには,NODから派生したメジャーヒストコンパティビリティ・コンプレックス (MHC) クラスII分子が,トランスジェニックTCRによって認識されることが含まれていた.
- 関節炎の進行にはCD4+T細胞,B細胞,骨髄性細胞が関与した.
結論:
- 関節の特定の疾患は,自己耐性の崩壊から生じ,全身的な自己反応性につながる可能性があります.
- このマウスモデルは,RAの病原性を研究するための貴重なツールを提供します.
- ヒトのRAは,全身的自己免疫を含む同様のメカニズムを通じて発症する可能性があります.

What is the Immune System?
Overview
Cell-mediated Immune Responses
Overview
Disorders of Leukocytes
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...

Special Features of Adaptive Immunity
The adaptive immune system, a crucial component of the overall immune response, offers a highly specialized defense against pathogens. It involves specific cell types and features, enabling it to combat infections effectively and efficiently.
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...

Antigens Involved in Adaptive Immunity
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
Complete Antigens
Complete antigens possess both immunogenicity and reactivity.

Autoimmune Disorders
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.
