背景情况:
- 类风湿性关节炎 (RA) 呈现出不同的病因和免疫失调状态.
- 通过外周血液免疫类型的患者分层可能会改善对分子向治疗的反应,包括生物/向合成疾病修饰性抗风湿药物 (b/tsDMARDs).
研究的目的:
- 基于外周血液免疫类型的RA患者分层.
- 评估分层的RA患者群体对b/tsDMARDs的治疗反应.
- 在一个独立的队列中验证分层方法.
主要方法:
- 流细胞计用于500多个b/tsDMARDs-naïveRA患者的免疫类型分析.
- 患者被分为多层次的集群,并评估了针对性治疗的治疗反应.
- 在另外一组183个b/tsDMARDs-naïve RA患者中进行了验证.
主要成果:
- RA 患者被分为五个分层; 两个表现出明显的表型,具有增加的 CD4 + 效应体记忆T 细胞.

T Cell Types and Functions
938
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

Diversity of Antigen Receptors
492
Antigen receptors are essential components of the immune system crucial in defending the body against foreign invaders. These receptors are present on the surface of B and T cells, enabling them to recognize antigens and mount an appropriate immune response.
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...

Blood Typing
1.1K
Understanding an individual's blood group is a critical component of transfusion medicine. It ensures compatibility in blood transfusions, organ transplants, and even during pregnancy. Determining these blood groups involves the ABO and Rh blood typing systems, utilizing specific antigens and corresponding anti-sera to identify an individual's blood type.
Antigens are protein molecules that reside on the surface of red blood cells (RBCs). The ABO and Rh blood typing systems target...
