Transport of the ribosome-inactivating protein ricin through endosomes was studied in A431 cells expressing Rab5-, Rab4-, and Rab11-GFP. It was shown that Rab5- and Rab4-positive functional domains of early endosomes are involved in ricin transport. Ricin enters cells by both clathrin-dependent and clathrin-independent mechanisms. The main pool of(More)
Binding of ricin and viscumin to paraformaldehyde fixed cell surface has been studied by confocal laser scanning microscopy (CLSM). Both toxins were labeled with different fluorochromes to allow for their identification after being applied jointly. The experiments indicated that viscumin and ricin bind to different cell receptors. Viscumin bound to the very(More)
Biofilm formation is an important part of the bacterial life cycle. Biofilms provide bacterial resistance to external stresses and protozoan grazing. Biofilm formation by the wild type of B. cenocepacia strain 370 in the presence of the free-living ciliate Tetrahymena pyriformis was studied. T. pyriformis grazed on planktonic bacteria and reduced the(More)
