まとめ

ランドスケープ展開顕微鏡法（land-ExM）は、信号品質を向上させることにより、細胞構造のイメージングを強化します。この超解像技術は、タンパク質と脂質を可視化し、オルガネの相互作用と相分離を明らかにします。

背景:

展開顕微鏡法（ExM）は超解像を提供するが、タンパク質と脂質の両方に対する高い信号対雑音比に苦労しています。
細胞機能の理解には、脂質やタンパク質を含む細胞構成要素の超微細構造の文脈の可視化が不可欠です。

結論:

Land-ExMは、細胞超微細構造の高コントラストイメージングのための強力な超解像プラットフォームを提供します。
この技術は、細胞内の膜オルガネと相分離との間の空間的協調の理解を前進させます。

Enlargement of the Plasma Membrane

Enlargement of the Plasma Membrane

Cell division and enlargement are processes that require precise control. The control ensures that cell division cannot proceed unless the cell has grown to a specific size. A spherical, dividing cell requires an approximately 1.6X increase in its surface area to double its volume. The secretory pathway also has a significant role in cell membrane enlargement. Secretory vesicles that bud off from the Golgi apparatus and later fuse with the plasma membrane during exocytosis are a major source of...

Fluid Mosaic Model

Fluid Mosaic Model

Scientists identified the plasma membrane in the 1890s and its principal chemical components (lipids and proteins) by 1915. The model for plasma membrane structure, proposed in 1935 by Hugh Davson and James Danielli, was the first model to be widely accepted in the scientific community. The model was based on the plasma membrane's "railroad track" appearance in early electron micrographs. Davson and Danielli theorized that the plasma membrane's structure resembled a sandwich...
