Encystment of Free-Living Amoebae, so Many Blind Spots to Cover

Parasitologia, 2023
Due to frequent variations in environmental conditions, free-living amoebae adapt through differentiation into different states. Hence, favorable conditions enable the formation of a feeding and proliferative form named “Trophozoïte” whereas unfavorable ...

Annual variation of in situ sedimentation of planktonic Ciliophora cysts in a temperate bay

Frontiers in Marine Science, 2023
Marine planktonic Ciliophora serve as a key component of the plankton food web. The formation of cysts is of common occurrence among planktonic Ciliophora, and encystment plays an important role in the persistence and diffusion of population.

Acanthamoeba spp. aggregate and encyst on contact lens material increasing resistance to disinfection

Frontiers in Microbiology, 2022
IntroductionAcanthamoeba keratitis is often caused when Acanthamoeba contaminate contact lenses and infect the cornea. Acanthamoeba is pervasive in the environment as a motile, foraging trophozoite or biocide-resistant and persistent cyst.

Analysis of Water-Soluble Proteins by Two-Dimensional Electrophoresis in the Encystment Process of Colpoda cucullus Nag-1 and Cytoskeletal Dynamics

Acta Protozoologica, 2021
Assays of protein contained in water-soluble fraction of encysting cells Colpoda cucullus Nag-1 by two-dimensional electrophoresis (2-D PAGE) and mass spectrometry (MS) revealed that the amount of β ...

A time-resolved multi-omics atlas of Acanthamoeba castellanii encystment

Nature Communications, 2022
Encystment is a process that allows free-living and parasitic amoebae to survive in unfavorable environments. Here, Bernard et al. provide detailed insights into the early stages of encystment of Acanthamoeba castellanii by integrating RNA-Seq ...

Transcriptome analysis reveals the encystment-related lncRNA expression profile and coexpressed mRNAs in Pseudourostyla cristata

Scientific Reports, 2021
Ciliated protozoans form dormant cysts for survival under adverse conditions. The molecular mechanisms regulating this process are critical for understanding how single-celled eukaryotes adapt to the environment.

ROP16-mediated activation of STAT6 enhances cyst development of type III Toxoplasma gondii in neurons.

PLoS Pathogens, 2023
Toxoplasma gondii establishes a long-lived latent infection in the central nervous system (CNS) of its hosts. Reactivation in immunocompromised individuals can lead to life threatening disease. Latent infection is driven by the ability of the parasite to

Encystment Induces Down-Regulation of an Acetyltransferase-Like Gene in Acanthamoeba castellanii

Pathogens, 2020
Acanthamoeba castellanii is a ubiquitous free-living amoeba. Pathogenic strains are causative agents of Acanthamoeba keratitis and granulomatous amoebic encephalitis. In response to adverse conditions, A.

Enhanced Biomass and Astaxanthin Production of Haematococcus pluvialis by a Cell Transformation Strategy with Optimized Initial Biomass Density

Marine Drugs, 2020
Astaxanthin from H. pluvialis is an antioxidant and presents a promising application in medicine for human health. The two-stage strategy has been widely adopted to produce astaxanthin by the Haematococcus industry and research community.

Phospholipase D in Phytophthora infestans and Its Role in Zoospore Encystment

Molecular Plant-Microbe Interactions, 2002
We show that differentiation of zoospores of the late blight pathogen Phytophthora infestans into cysts, a process called encystment, was triggered by both phosphatidic acid (PA) and the G-protein activator mastoparan. Mastoparan induced the accumulation
