    • From fixed-dried to wet-fixed to live-comparative super-resolution microscopy of liver sinusoidal endothelial cell fenestrations 

      Szafranska, Karolina; Neuman, Tanja; Baster, Zbigniew; Rajfur, Zenon; Szelest, Oskar; Holte, Christopher Florian; Kubisiak, Agata; Kus, Edyta; Wolfson, Deanna; Chlopicki, Stefan; Ahluwalia, Balpreet Singh; Lekka, Malgorzata; Szymonski, Marek; McCourt, Peter Anthony; Zapotoczny, Barlomiej (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-20)
      Fenestrations in liver sinusoidal endothelial cells (LSEC) are transcellular nanopores of 50–350 nm diameter that facilitate bidirectional transport of solutes and macromolecules between the bloodstream and the parenchyma of the liver. Liver diseases, ageing, and various substances such as nicotine or ethanol can negatively influence LSECs fenestrations and lead to defenestration. Over the years, ...

    • Tuning of Liver Sieve: The Interplay between Actin and Myosin Regulatory Light Chain Regulates Fenestration Size and Number in Murine Liver Sinusoidal Endothelial Cells 

      Zapotoczny, Barlomiej; Szafranska, Karolina; Lekka, Malgorzata; Ahluwalia, Balpreet Singh; McCourt, Peter Anthony (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-30)
      Liver sinusoidal endothelial cells (LSECs) facilitate the efficient transport of macromolecules and solutes between the blood and hepatocytes. The efficiency of this transport is realized via transcellular nanopores, called fenestrations. The mean fenestration size is 140 ± 20 nm, with the range from 50 nm to 350 nm being mostly below the limits of diffraction of visible light. The cellular ...
