Long-term dynamics of placozoan culture: emerging models for population and space biology [PDF]

Frontiers in Cell and Developmental Biology
As the simplest free-living animal, Trichoplax adhaerens (Placozoa) is emerging as a powerful paradigm to decipher molecular and cellular bases of behavior, enabling integrative studies at all levels of biological organization in the context of metazoan ...

Coordinated cellular behavior regulated by epinephrine neurotransmitters in the nerveless placozoa [PDF]

Nature Communications
Understanding how cells communicated before the evolution of nervous systems in early metazoans is key to unraveling the origins of multicellular life.

Cytoplasmic Vibrations Due to Flagellar Beating in Trichoplax adhaerens F. E. Schulze (Placozoa)* [PDF]

Zeitschrift für Naturforschung C, 1990
Abstract The dorsal epithelium of the plate-like primitive metazoon Trichoplax adhaerens is a sheet of flat cells, each bearing a single flagellum. This layer rests largely on an intercellular fluid and is predominantly fixed at the edges of the organism but also locally by fibre cells constituting the middle layer of the animal. Within

Multi-domain O-GlcNAcase structures reveal allosteric regulatory mechanisms [PDF]

Nature Communications
Nucleocytoplasmic protein O-GlcNAcylation is a dynamic modification catalysed by O-GlcNAc transferase (OGT) and reversed by O-GlcNAc hydrolase (OGA), whose activities are regulated through largely unknown O-GlcNAc-dependent feedback mechanisms.

Das radialpolare Differenzierungsmuster bei Trichoplax adhaerens F. E. Schulze (Placozoa) / The Radial Polar Pattern of Differentiation in Trichoplax adhaerens F. E. Schulze (Placozoa) [PDF]

Zeitschrift für Naturforschung C, 1984
Abstract In contrast with the outmost uniform aspect of Trichoplax there is a clear cut differentiation between marginal and central cell territories. Dissection and transplantation as well as vital staining show that the marginal material is restricted to a seam approximately 20 μm in width, surrounding the much larger mass of central ...

Insights into the evolution of digestive systems from studies of Trichoplax adhaerens [PDF]

Cell and Tissue Research, 2019
Trichoplax, a member of the phylum Placozoa, is a tiny ciliated marine animal that glides on surfaces feeding on algae and cyanobacteria. It stands out from other animals in that it lacks an internal digestive system and, instead, digests food trapped under its lower surface.

The Mesenchyme-Like Layer of the Fiber Cells of Trichoplax adhaerens (Placozoa), a Syncytium [PDF]

Zeitschrift für Naturforschung C, 1995
Abstract The fiber cells of the middle layer of Trichoplax adhaerens are interconnected by slender extensions. Newly formed connections after mechanical disruption of the tissue studied in ultrathin sections revealed cytoplasmic continuity between the cell bodies, suggesting a syncytial organisation of the fiber cell layer.

Evolution of iGluR ligand specificity, polyamine regulation, and ion selectivity inferred from a placozoan epsilon receptor [PDF]

Communications Biology
Epsilon ionotropic glutamate receptors (iGluRs) are a recently defined clade of neurotransmitter receptors that are found in all major metazoan lineages that are distinct from α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA), kainate, delta ...
