Life cycle strategies in free‐living unicellular eukaryotes: Diversity, evolution, and current molecular tools to unravel the private life of microorganisms

Journal of Eukaryotic Microbiology, Volume 71, Issue 6, November/December 2024.
Abstract An astonishing range of morphologies and life strategies has arisen across the vast diversity of protists, allowing them to thrive in most environments. In model protists, like Tetrahymena, Dictyostelium, or Trypanosoma, life cycles involving multiple life stages with different morphologies have been well characterized.

Convective Instability and Boundary Driven Oscillations in a Reaction-Diffusion-Advection Model

, 2017
In a reaction-diffusion-advection system, with a convectively unstable regime, a perturbation creates a wave train that is advected downstream and eventually leaves the system.

Whole Genome Sequencing of Mutation Accumulation Lines Reveals a Low Mutation Rate in the Social Amoeba Dictyostelium discoideum

PLoS ONE, 2012
Spontaneous mutations play a central role in evolution. Despite their importance, mutation rates are some of the most elusive parameters to measure in evolutionary biology.

Ancestral TALE homeobox protein transcription factor regulates actin dynamics and cellular activities of protozoan parasite Entamoeba invadens

Molecular Microbiology, Volume 122, Issue 5, Page 660-682, November 2024.
Localization of polymerized actin sowing different arrangements of actin during different cellular activities in Entamoeba, like phagocytotic cup, phagosome, capping, cortical and posterior regions, and pseudopods. Abstract Entamoeba histolytica causes invasive amoebiasis, an important neglected tropical disease with a significant global health impact.

SILAC-based proteomic quantification of chemoattractant-induced cytoskeleton dynamics on a second to minute timescale [PDF]

, 2014
Cytoskeletal dynamics during cell behaviours ranging from endocytosis and exocytosis to cell division and movement is controlled by a complex network of signalling pathways, the full details of which are as yet unresolved.

Enhanced Enzyme Immobilization Using a Novel Agarose‐binding Tag Leads to Improved Flow Reactor Performance

ChemCatChem, Volume 16, Issue 19, October 7, 2024.
To enhance enzyme retention within agarose hydrogels, a carbohydrate‐binding module (MtCBM) derived from Microbulbifer thermotolerans thermostable β‐agarase I was utilized as a versatile agarose‐binding tag. MtCBM displayed heightened binding affinity towards unmelted agarose, and fusion proteins incorporating MtCBM exhibited improved retention within ...

Contact-controlled amoeboid motility induces dynamic cell trapping in 3D-microstructured surfaces. [PDF]

, 2012
On flat substrates, several cell types exhibit amoeboid migration, which is characterized by restless stochastic successions of pseudopod protrusions. The orientation and frequency of new membrane protrusions characterize efficient search modes, which ...

Functional Characterization of a Novel Aquaporin from Dictyostelium discoideum Amoebae Implies a Unique Gating Mechanism*

Journal of Biological Chemistry, 2012
Background: Aquaporins are involved in osmoregulation and cell motility. Functional D. discoideum aquaporins are missing. Results: We characterized a putatively gated aquaporin from amoebae that localizes to vacuolar structures, the plasma membrane, and ...

Social amoebae trap and kill bacteria by casting DNA nets

Nature Communications, 2016
Neutrophils secrete net-like structures made of DNA and anti-microbial peptides, which can trap and kill extracellular pathogens. Here, the authors show that such nets are also produced by so-called Sentinel cells in the multicellular slug stage of the ...

Functional Characterization of the Plasmodium falciparum Chloroquine-Resistance Transporter (PfCRT) in Transformed Dictyostelium discoideum Vesicles

PLoS ONE, 2012
Background Chloroquine (CQ)-resistant Plasmodium falciparum malaria has been a global health catastrophe, yet much about the CQ resistance (CQR) mechanism remains unclear.
