Physiology and evolution of voltage-gated calcium channels in early diverging animal phyla: Cnidaria, Placozoa, Porifera and Ctenophora

Frontiers in Physiology, 2016
Voltage-gated calcium (Cav) channels serve dual roles in the cell, where they can both depolarize the membrane potential for electrical excitability, and activate transient cytoplasmic Ca2+ signals.

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

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.

First record of Placozoa from the Gulf of Mexico

Hidrobiológica, 2017
Placozoa is a phylum with only one species:Trichoplax adhaerens (F. E. Schulze, 1883); recent genetic studies suggest, however,that several haplotypes inhabit tropical and subtropical waters around the world. Placozoans have been found usually close to littoral zones where mangrove forests occur. Goals. To provide the second record of this species from

Early Animal Origin of BACE1 APP/Aβ Proteolytic Function

Biology
Alzheimer’s disease is characterized, in part, by the accumulation of β-amyloid (Aβ) in the brain. Aβ is produced via the proteolysis of APP by BACE1 and γ-secretase.

Telomeres and telomerase in basal Metazoa

Invertebrate Survival Journal, 2017
Telomeres are protein-bound tandemly repeated simple DNA sequences placed at the chromosome ends, their role being essential for maintaining genome integrity.

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

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 ...
