Ascidian Tunicate Extracts Attenuate Rheumatoid Arthritis in a Collagen-induced Murine Model

open access: yesNatural Product Communications, 2014
Murine rheumatoid arthritis models are often used to investigate the potential therapeutic effects of candidate drugs. The present study has been conducted in order to investigate the therapeutic efficacy of ascidian tunicate extracts in a collagen ...

Inferring Tunicate Relationships And The Evolution Of The Tunicate Hox Cluster With The Genome Of Corella Inflata [PDF]

open access: yes, 2020
Tunicates, the closest living relatives of vertebrates, have served as a foundational model of early embryonic development for decades. Comparative studies of tunicate phylogeny and genome evolution provide a critical framework for analyzing chordate ...

The planktonic food web in the Gulf of Naples based on the analysis of carbon and nitrogen stable isotope ratios

open access: yesMarine 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 ...

Asymmetric Fitness of Second-Generation Interspecific Hybrids Between Ciona robusta and Ciona intestinalis

open access: yesG3: Genes, Genomes, Genetics, 2020
Reproductive isolation is central to speciation, but interspecific crosses between two closely related species can produce viable and fertile hybrids.

Evolution of Allorecognition in the Tunicata

open access: yesBiology, 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

open access: yesFrontiers 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

open access: yesCells, 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]

open access: yesInvertebrate 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 ...
