背景情况:

移植获得过敏 (TAA) 在儿科肝移植接受者中被认可.
在异性造血细胞移植 (allo-HCT) 后的TAA的临床特征和机制仍然不完全理解.
观察到的TAA表现包括湿疹性皮肤炎,过敏性鼻炎和喘.

研究的目的:

为了阐明TAA的临床特征在alo-HCT的背景下.
探索推动TAA在HCT合后发展的潜在机制.
确定影响TAA患病率和表现的因素.

主要方法:

对TAA在各HCT中的现有文献的综述.
从回顾性研究中分析临床数据 (如有).
讨论潜在的免疫路径,如记忆B细胞转移和Th2反应.

主要成果:

过敏性疾病可以通过alo-HCT从过敏的捐赠者转移到非过敏的接受者.
潜在的机制包括过敏原特异性记忆B细胞的转移,促进Th2-歪曲的免疫反应.
追溯数据表明,带血移植 (CBT) 和塔克罗利斯可能会影响TAA的发展.

结论:

TAA是alo-HCT的潜在并发症,具有不同的临床表现.
了解机制和风险因素需要进一步调查.
前性研究至关重要,以建立关于TAA患病率和相关风险因素的强有力的证据.

Hypersensitivities

Hypersensitivities

Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Tissue Transplantation

Tissue Transplantation

Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.
The Biology of Tissue Transplantation
The biology of tissue transplantation hinges on the Major Histocompatibility Complex (MHC) molecules. These molecules...
