      Hunt, Nicholas J; McCourt, Peter Anthony; Kuncic, Zdenka; Le Couteur, David G; Cogger, Victoria C (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-25)
      Nanotherapeutics utilize the properties of nanomaterials to alter the pharmacology of the drugs and therapies being transported, leading to changes in their biological disposition (absorption, distribution, cellular uptake, metabolism and elimination) and ultimately, their pharmacological effect. This provides an opportunity to optimize the pharmacology of drugs, particularly for those that are ...
    • Mechanisms of Selective Autophagy 

      Lamark, Trond; Johansen, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-21)
      Selective autophagy is the lysosomal degradation of specific intracellular components sequestered into autophagosomes, late endosomes, or lysosomes through the activity of selective autophagy receptors (SARs). SARs interact with autophagy-related (ATG)8 family proteins via sequence motifs called LC3-interacting region (LIR) motifs in vertebrates and Atg8-interacting motifs (AIMs) in yeast and plants. ...
