科学领域:

免疫学免疫学免疫学
内分泌学在内分泌学.
斑马鱼模型斑马鱼模型

背景情况:

葡萄糖皮质体 (GCs) 抑制免疫力,主要通过葡萄糖皮质体受体 (GR).
皮质醇,一个关键的GC,也通过矿物质皮质醇受体 (MR) 发出信号.
人们还不太了解MR的免疫调节作用.

研究的目的:

研究MR在炎症期间调节白细胞功能的作用.

Receptor Downregulation in MVBs

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that lead to cell proliferation, migration, and differentiation. Overexpression of EGFR stimulates cells to proliferate. Excessive EGFR...
