Effects of the surface charge of polyamidoamine dendrimers on cellular exocytosis and the exocytosis mechanism in multidrug-resistant breast cancer cells

Journal of Nanobiotechnology, 2021
Background Polyamidoamine (PAMAM) dendrimer applications have extended from tumor cells to multidrug-resistant tumor cells. However, their transportation in multidrug-resistant tumor cells remains unclear.

Effect of the T-domain on intracellular transport of diphtheria toxin [PDF]

The Ukrainian Biochemical Journal, 2014
Subunit B of diphtheria toxin (DT), which consists of two domains: R (receptor-binding) and T (transmembrane), plays an important role in toxin-receptor binding on the cell-targets and in transportation of catalytic subunit A to the cell cytosol ...

Cytoplasmic tail determines the membrane trafficking and localization of SARS-CoV-2 spike protein

Frontiers in Molecular Biosciences, 2022
The spike (S) glycoprotein of SARS-CoV-2 mediates viral entry through associating with ACE2 on host cells. Intracellular trafficking and palmitoylation of S protein are required for its function.

Intracellular Cholesterol Synthesis and Transport

Frontiers in Cell and Developmental Biology, 2022
Cholesterol homeostasis is related to multiple diseases in humans, including cardiovascular disease, cancer, and neurodegenerative and hepatic diseases. The cholesterol levels in cells are balanced dynamically by uptake, biosynthesis, transport, distribution, esterification, and export.

Intracellular cholesterol transport

Journal of Lipid Research, 1997
Recent data on the roles of vesicle- and 'raft'-mediated pathways in intracellular free cholesterol (FC) transport are reviewed. Cholesterol internalized from plasma lipoproteins is transferred via endocytic vesicles to the trans-Golgi network (TGN), consistent with prior data indicating a key role for this organelle in protein and lipid sorting and ...
