Marine Ecology, EarlyView., 2023 Abstract Plankton play a key role in marine food webs by producing and transferring organic matter and energy to higher trophic levels. To define the trophic structure and interactions within the planktonic communities in the Gulf of Naples, we determined carbon and nitrogen stable isotope ratios in particulate organic matter (POM, <20 μm ...

An FGF-driven feed-forward circuit patterns the cardiopharyngeal mesoderm in space and time
eLife, 2018 In embryos, multipotent progenitors divide to produce distinct progeny and express their full potential. In vertebrates, multipotent cardiopharyngeal progenitors produce second-heart-field-derived cardiomyocytes, and branchiomeric skeletal head muscles ...

Evolution of Allorecognition in the Tunicata
Biology, 2020 Allorecognition, the ability to distinguish self or kin from unrelated conspecifics, plays several important biological roles in invertebrate animals. Two of these roles include negotiating limited benthic space for colonial invertebrates, and inbreeding

Evolution of CDK1 Paralog Specializations in a Lineage With Fast Developing Planktonic Embryos
Frontiers in Cell and Developmental Biology, 2022 The active site of the essential CDK1 kinase is generated by core structural elements, among which the PSTAIRE motif in the critical αC-helix, is universally conserved in the single CDK1 ortholog of all metazoans.

Serotonin Receptors and Their Involvement in Melanization of Sensory Cells in Ciona intestinalis
Cells, 2023 Serotonin (5-hydroxytryptamine (5-HT)) is a biogenic monoamine with pleiotropic functions. It exerts its roles by binding to specific 5-HT receptors (5HTRs) classified into different families and subtypes.

Inflammatory hemocytes in Ciona intestinalis innate immune response [PDF]
Invertebrate Survival Journal, 2009 In the present paper an attempt is carried out to revise Ciona intestinalis inflammatory hemocytes according to their morphology as formerly observed by light and electron microscopy, and taking in account recent reports on innate immunity gene ...

A novel third complement component C3 gene of Ciona intestinalis expressed in the endoderm at the early developmental stages [PDF]
Invertebrate Survival Journal, 2013 The third complement component (C3) in ascidian was reported to function as an opsonin to enhance phagocytosis and as a chemotactic factor for phagocytes, indicating that ascidian C3 works in mesodermal cavity as a humoral factor like vertebrate C3s.
