Dissecting a peptidergic signaling pathway in Trichoplax adhaerens by gene silencing
Current BiologyTrichoplax adhaerens, a simple multicellular marine organism from the phylum Placozoa,1,2 is one of the most basal metazoan lineages, alongside Ctenophora, Porifera, and Cnidaria.3,4,5 With its remarkably simple body plan,6,7Trichoplax provides valuable insights into the evolution of multicellularity.8,9 Interestingly, despite lacking true tissues and ...

A multiagent multicellular systems biology model of Trichoplax adhaerens
2008 IEEE International Conference on Electro/Information Technology, 2008We present an agent-based simulation model of the animal Trichoplax adhaerens (phylum: Placozoa). The model attempts to simulate the whole organism based on a cellular-level description. The question we wish to address is: How does whole organism morphology and behavior emerge from cellular activity? A prototype animal model was specified, designed and

The cytoskeleton of the fiber cells of Trichoplax adhaerens (Placozoa)
Zoomorphology, 1986The cytoskeleton of Trichoplax adhaerens fiber cells was studied after chemical fixation, freeze-substitution, lysis of attached cells with nonionic detergents and by immunofluorescence. Cytoskeletal elements present in the cell bodies and reaching into the extensions include microtubules, intermediate filaments, 6–7 nm and 2–3 nm microfilaments.

Trichoplax adhaerens, an Enigmatic Basal Metazoan with Potential
2014Trichoplax adhaerens is an enigmatic basal animal with an extraordinarily simple morphological organization and surprisingly complex behaviors. Basic morphological, molecular and behavioral work is essential to better understand the unique and curious life style of these organisms.

Bioinformatic prediction of Trichoplax adhaerens regulatory peptides
General and Comparative Endocrinology, 2015Trichoplax adhaerens (phylum Placozoa) is a very simple organism that lacks a nervous system. However, its genome contains many genes essential for neuronal function and development. I report the results of regulatory peptide predictions for this enigmatic animal. Extensive transcriptome, genome, and predicted proteome mining allowed us to predict four

Expression pattern of the homeobox gene Not in the basal metazoan Trichoplax adhaerens
Gene Expression Patterns, 2004The homeobox gene Not is highly conserved in Xenopus, chicken and zebrafish with an apparent role in notochord formation, which inspired the name of this distinct subfamily. Interestingly, Not genes are also well conserved in animals without notochord such as sea urchins, Drosophila or even Hydra, but appear to be highly derived in mammals.

My favorite animal, Trichoplax adhaerens
BioEssays, 2005AbstractTrichoplax adhaerens is more simply organized than any other living metazoan. This tiny marine animal looks like a irregular “hairy plate” (“tricho plax”) with a simple upper and lower epithelium and some loose cells in between. After its original description by F.E.

Disaggregation and Reaggregation of Cells of the Primitive Metazoon Trichoplax adhaerens
Differentiation, 1979Trichoplax cells can be dispersed after the action of colchicine, vinblastine, and sea water free of divalent ions. Since lumicolchicine, which is inactive against microtubules can also cause disaggregation, the plant alkaloids are thought to be bound to components of the cell membrane involved in cellular adhesion. After washing, the cells reaggregate

Functional Studies of Trichoplax adhaerens Voltage-Gated Calcium Channel Activity
2020Trichoplax adhaerens is a member of the phylum Placozoa, an enigmatic group of benthic animals with remarkably simple morphology. While initial work on these organisms has primarily focused on their morphology and the development of genomic resources, Trichoplax has received increased attention as a model for studying the evolution of nervous and ...
