概括
周围血液检测可以帮助检测移植排斥. 常规血液检测和淋巴细胞亚种群的变化与T细胞介导排斥 (TCMR) 和抗体介导排斥 (ABMR) 相相关,有助于诊断.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學.
- 免疫学 免疫学 免疫学
- 移植手术 移植手术
背景情况:
- 移植脏的拒绝仍然是移植存活的主要挑战.
- 活检虽然是最终的,但是侵入性的,不适合常规监测.
- 周围血液淋巴细胞亚种群分析为免疫评估提供了一种不那么侵入性的方法.
研究的目的:
- 调查外围血液淋巴细胞亚群与T细胞介导排斥 (TCMR) 和抗体介导排斥 (ABMR) 在移植受体之间的关系.
- 为了评估这些淋巴细胞亚种群的诊断价值,与常规血液检测一起进行.
- 探索移植拒绝的潜在预测模型.
主要方法:
- 对154名移植接受者的回顾性分析.
- 根据排斥状态将其分类为稳定,TCMR和ABMR组.
- 在治疗前的小组中,对功能,常规血液检查和外周血液淋巴细胞亚群的比较.
主要成果:
- 拒绝 (TCMR和ABMR) 与功能受损 (肌素和BUN升高,EGFR降低) 有关.
- 在例行血液检测中观察到明显的变化:ABMR显示血红蛋白,红细胞和血小板数量较低;TCMR和ABMR显示中性粒细胞百分比较高.
- 无论是TCMR和ABMR组都表现出较低的淋巴细胞数量和特定亚群变化 (例如TCMR中减少的CD4+T细胞).
结论:
- 移植脏的拒绝会显著改变常规血液检测参数和外围血液淋巴细胞亚群.
- 这些变化的特定模式可能有助于预测和诊断TCMR和ABMR,区分两种类型的排斥.

Blood Transfusion and Agglutination
10.8K
Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Blood transfusion is a critical medical procedure that saves lives and treats various medical conditions. It involves transferring blood from a donor to a recipient. This process requires a thorough understanding of the ABO blood group system and its associated antigens and antibodies.
Blood Transfusion Overview
A blood transfusion is a medical procedure used to replace blood lost due to injury, surgery, or to treat conditions such as anemia or cancer. During a transfusion, donor blood is...

Special Features of Adaptive Immunity
794
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,...

Cells of the Adaptive Immune Response
977
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...
