background : acanthamoeba castellanii forms a resistant cyst that protects the para-site against the host’s immune response. acanthamoeba type-i metacaspase (acmcp) is a caspase-like protein that has been found to be expressed during the encysta-tions. dictyostelium discoideum is an organism closely related to acanthamoeba useful for studying the molecular function of this protozoan caspase-lik...
In plants, as in animals, programmed cell death (PCD) is a key process responsible for the elimination of unneeded structures and for overall shape remodeling during development [1]; however, the molecular mechanisms remain poorly understood. Despite the absence of canonical caspases in plants, dying plant cells show an increased proteolytic caspase-like activity [2]. Moreover, the cell death c...
We analyzed the effects of temperature on the interaction of Legionella pneumophila with Acanthamoeba castellanii. At <20 degrees C, overexpression of type 1 metacaspase, a stimulator of A. castellanii encystation, was associated with a reduced number of bacteria within amoeba. At low temperatures, A. castellanii seems to eliminate L. pneumophila by encystation and digestion.
Protein glycolysation is an essential posttranslational modification in eukaryotic cells. In pathogenic yeasts, it is involved in a large number of biological processes, such as protein folding quality control, cell viability and host/pathogen relationships. A link between protein glycosylation and apoptosis was established by the analysis of the phenotypes of oligosaccharyltransferase mutants ...
