概括
剖腹产可能与女性患多发性硬化症 (MS) 的风险增加有关. 这种关联是在一项大型加拿大研究中观察到的,但对于其他自身免疫性疾病 (如乳病或类风湿性关节炎) 没有发现.
科学领域:
- 生殖健康 生殖健康
- 免疫学 免疫学 免疫学
- 流行病学 流行病学
背景情况:
- 剖腹产是一种常见的分娩程序,具有潜在的长期健康影响.
- 自身免疫性疾病影响了女性人口的很大一部分.
- 了解自身免疫性疾病的风险因素对于早期发现和预防至关重要.
研究的目的:
- 调查一次性剖腹产与女性自身免疫性疾病发生率之间的关联.
- 评估在剖腹产和阴道分娩后患乳病,多发性硬化症 (MS),类风湿性关节炎 (RA) 和全身自身免疫性类风湿性疾病 (SARD) 的风险.
主要方法:
- 一项以人口为基础的队列研究包括加拿大安大略省的253,901名女性,她们在2012-2017年间进行了第一次分娩.

Autoimmune Disorders
379
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.

Pathophysiology of Diabetes
852
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Development of Immunocompetence
282
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Transcytosis of IgG
2.7K
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

Oogenesis
63.4K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
