… The proteins that compose the intermediate filaments vary depending on the cell type, and are thought to be related to the specificity of each cell's structure and function. Epithelial cells have cytokeratin, mesenchymal cells and other cells have vimentin, muscle cells have desmin, nerve cells have neurofilament protein, and glial cells have glial cell-specific filament protein, which form the intermediate filaments of each cell type. The mesh structure of the intermediate filaments first forms a cage-like structure that surrounds the nucleus, and on the other hand, forms a mesh structure that runs like a hook from the attachment point on the cell membrane to the attachment point on the distant cell membrane. … *Some of the terminology that mentions "cytokeratin" is listed below.

… 中間繊維の構成タンパク質は,細胞種によって異なり,それぞれの細胞構造や機能の特異性に関係していると思われる。上皮細胞にはサイトケラチンcytokeratin,間充織細胞その他の細胞にはビメンチンvimentin,筋細胞にはデスミンdesmin,神経細胞にはニューロフィラメントタンパク質neurofilament protein,グリア細胞にはグリア細胞特異的フィラメントタンパク質があって,それぞれの細胞種における中間繊維を形づくっている。中間繊維の網目状構造は,まず核を取り囲む籠状の構造を形づくり,一方では,細胞膜上の付着点に発し,離れた細胞膜上の付着点に至るかすがい状に走る網目状の構造を形づくっている。… ※「cytokeratin」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
