概括
一个新的纳米输送平台 (IMNP) 针对内皮细胞和T细胞,以对抗多发性硬化症 (MS). 这种方法抑制了内皮细胞到介质细胞的过渡,并减少了神经炎症,改善了MS模型的结果.
科学领域:
- 免疫学 免疫学 免疫学
- 纳米技术纳米技术
- 神经科学是一个神经科学.
背景情况:
- 目前针对T细胞或B细胞的多发性硬化症 (MS) 治疗由于MS的发病复杂性而具有有限的疗效.
- 内皮转移到介质细胞转移 (EndMT) 和免疫透创造了一个循环,加剧了MS中血脑屏障 (BBB) 破坏和神经炎症.
研究的目的:
- 开发一个多功能纳米输送平台 (IMNP) 用于MS的双血管-免疫调制.
- 针对内皮细胞和T细胞的共享IL7R进行协同治疗效果.
主要方法:
- scRNA-seq确定IL7R是内皮细胞和致病性T细胞的共同目标.
- 一个纳米输送平台 (IMNP) 用ETS1等离子体DNA,聚β氨基 (PBAE),IL7R向 (ITP) 和巨细胞膜 (MM) 涂层进行了工程设计.
- 在复发性复发性多发性硬化症 (RRMS) 和二次进展性多发性硬化症 (SPMS) 模型中评估IMNP的疗效.
主要成果:
- IMNP优先聚集在血管内皮,抑制EndMT并保持BBB的完整性.
- IMNP减弱了CD4+T细胞分化到促炎的Th1/Th17子集,减少了中枢神经系统的透.

Active versus Passive Immunity
10.7K
Immunity, along with the ability to limit pathogen growth to prevent significant body tissue damage, can be gained either by (1) actively developing an immune response within the individual after exposure to a pathogen or after getting vaccinated or (2) passively transferring immune components from an immune individual to one who is nonimmune. Both these forms of immunity can be found naturally and in medical practices.

Introduction to Lymphatic and Immune System
17.3K
Immunity is a crucial biological concept about our body's inherent capacity to prevent infections and diseases. A complex network of cells and tissues collectively known as the immune system facilitates this natural defense mechanism. The immune system plays an integral role in maintaining our health and well-being, shielding us from potential health threats.
The immune responses can be categorized into two types: innate and adaptive. Innate immunity comprises nonspecific defenses we are...

Functions of the Lymphatic and Immune System
6.7K
The lymphatic system plays a crucial role in bolstering our immune system. It consists of a network of lymphoid organs, lymph, and lymphatic vessels that provide structural and functional support in safeguarding the body against pathogens such as viruses and bacteria.
The primary lymphoid organs, including the bone marrow and the thymus, serve as the maturation sites for lymphocytes. Secondary lymphoid organs, like the mucosa-associated lymphoid tissue, activate these lymphocytes and serve as...
