Studies on the Structure of the Brooding Organs of Two Botryllid Ascidians, Botryllus delicatus and Botryllus sexiens [PDF]

Zoological Science, 2001
Abstract The formative processes of the brooding organs of two botryllid ascidians, Botryllus delicatus and Botryllus sexiens, were observed. The structure of these organs was also studied in detail histologically. The brooding organs of these two species were formed from the branchial sac, in contrast to the brooding organs of other botryllids, which ...

Botryllin, a Novel Antimicrobial Peptide from the Colonial Ascidian Botryllus schlosseri

Marine Drugs, 2023
By mining the transcriptome of the colonial ascidian Botryllus schlosseri, we identified a transcript for a novel styelin-like antimicrobial peptide, which we named botryllin.

Insights on cytotoxic cells of the colonial ascidian Botryllus schlosseri [PDF]

Invertebrate Survival Journal, 2015
Morula cells (MCs) represent the most abundant circulating hemocyte of the compound ascidian Botryllus schlosseri. They are cytotoxic cells involved in the rejection reaction between contacting, genetically incompatible colonies.

The Onset of Whole-Body Regeneration in Botryllus schlosseri: Morphological and Molecular Characterization

Frontiers in Cell and Developmental Biology, 2022
Colonial tunicates are the only chordates that regularly regenerate a fully functional whole body as part of their asexual life cycle, starting from specific epithelia and/or mesenchymal cells.

Yamanaka Factors in the Budding Tunicate Botryllus schlosseri Show a Shared Spatio-Temporal Expression Pattern in Chordates

Frontiers in Cell and Developmental Biology, 2022
In vertebrates, the four transcription factors Sox2, c-Myc, Pou5f1 and Klf4 are involved in the differentiation of several tissues during vertebrate embryogenesis; moreover, they are normally co-expressed in embryonic stem cells and play roles in ...

Suppression of cell-spreading and phagocytic activity on nano-pillared surface: in vitro experiment using hemocytes of the colonial ascidian Botryllus schlosseri [PDF]

Invertebrate Survival Journal, 2015
Nano-scale nipple array on the body surface has been described from various invertebrates including endoparasitic and mesoparasitic copepods, but the functions of the nipple array is not well understood.

Proteome‐Wide 4‐Hydroxy‐2‐Nonenal Signature of Oxidative Stress in the Marine Invasive Tunicate Botryllus schlosseri

PROTEOMICS, Volume 25, Issue 19, Page 12-25, October 2025.
ABSTRACT The ascidian Boytryllus schlosseri is a marine chordate that thrives under conditions of anthropogenic climate change. The B. schlosseri expressed proteome contains unusually high levels of proteins adducted with 4‐hydroxy‐2‐nonenal (HNE). HNE represents a prominent posttranslational modification resulting from oxidative stress.

Deep quantitative proteomics of North American Pacific coast star tunicate (Botryllus schlosseri)

PROTEOMICS, Volume 24, Issue 15, August 2024.
Abstract Botryllus schlosseri, is a model marine invertebrate for studying immunity, regeneration, and stress‐induced evolution. Conditions for validating its predicted proteome were optimized using nanoElute® 2 deep‐coverage LCMS, revealing up to 4930 protein groups and 20,984 unique peptides per sample.

Unconventional secretion of a rhamnose-binding lectin by Botryllus schlosseri phagocytes

The European Zoological Journal
Botryllus schlosseri is a colonial tunicate diffuse in shallow waters of all seas and oceans. When B. schlosseri haemocytes are challenged with nonself, circulating phagocytes respond to the recognition of foreign molecules with the synthesis and ...
