Placozoa

2023
PREFAZIONE Perché un nuovo testo di Zoologia? La risposta sta innanzitutto nella quantità di nuove informazioni, derivanti dagli studi basati sull’uso di approcci cladistici e molecolari, che hanno rivoluzionato le nostre conoscenze sui rapporti filogenetici tra gli animali, soprattutto invertebrati.

Spherical forms ofTrichoplax adhaerens (Placozoa)

Zoomorphology, 1990
Two types of spherical forms of this normally flattened organism appear sporadically in our cultures. Hollow spheres have an outer wall of flagellated ventral epithelium. The large fiber cells protrude into the central cavity which can include a closed compartment of flagellated dorsal epithelium.

The cytoskeleton of the fiber cells of Trichoplax adhaerens (Placozoa)

Zoomorphology, 1986
The 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.

Microfilaments and microtubules in isolated fiber cells of Trichoplax adhaerens (Placozoa)

Zoomorphology, 1989
Fiber cells isolated by mechanical disruption of the tissue in Ca2+-free sea water attach firmly to the substrate by discrete adhesion plaques. They are capable of forming a lamellipodium and long, slender extensions while the cell bodies remain stationary. The extensions are slowly elongated but can suddenly be withdrawn by contraction.

Does apicortin, a characteristic protein of apicomplexan parasites and placozoa, occur in Eumetazoa?

Acta Parasitologica, 2018
Apicortin is a characteristic protein of apicomplexan parasites which has recently been identified in their free-living cousins, chromerids as well. The placozoan Trichoplax adhaerens is the only animal possessing this protein and apicortin is one of its

Alternative modes of asexual reproduction inTrichoplax adhaerens (Placozoa)

Zoomorphology, 1991
Hollow swarmers are budded off at the dorsal surface ofTrichoplax and are covered by dorsal epithelium. Their inner cavity is lined with the flagellated cells of the ventral epithelium. There is no indication that the fiber cells included between the epithelia take any part either in morphologenesis or the separation of the bud from the mother animal ...
