- 免疫学 免疫学 免疫学
背景情况:
- 聚乳糖合糖酸 (PLGA) 纳米颗粒是FDA批准的,可生物降解和生物相容的材料.
- 然而,PLGA纳米颗粒在体内表现出短的生物半衰期,这是由于单核细胞系统的快速清除,导致肝脏和脏中的积累.
研究的目的:
- 分析与人体血和血清化后PLGA纳米颗粒上的蛋白质吸附模式.
- 为了研究不同纳米粒子稳定剂对生物分子冠状体形成的影响.
- 了解生物分子冠状体在PLGA纳米粒子体内行为中的作用.
主要方法:
- 用人类血和血清化PLGA纳米颗粒.
- 吸附蛋白质的量化. 吸附蛋白质的量化.
- 使用液体染色学-并联质谱法 (LC-MS/MS) 识别和量化吸附的蛋白质.
主要成果:
- 在PLGA纳米粒子表面显著丰富opsonin和耗尽dysopsonins.
- 生物分子冠状体的形成与优选吸附的opsonins.
- 不同的稳定剂影响了结合蛋白的总量,但对冠状的组成影响很小.
结论:
- 富含松素的生物分子冠状体的形成是PLGA纳米颗粒在体内不良行为的可能解释.
- 虽然稳定剂可以影响总蛋白质吸附,但它们极少改变生物分子冠状结构.

Covalently Linked Protein Regulators
8.2K
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.

Lipids as Anchors
6.0K
In the plasma membrane, the lipids forming the bilayer can also act as an anchor to tether proteins to the membrane. The three main types of lipid anchors found in eukaryotes are – prenyl groups, fatty acyl groups, and glycosylphosphatidylinositol or GPI groups. Prenyl and fatty acyl groups act as anchors on the cytosolic surface of the membrane, whereas GPI anchors proteins on the extracellular side.
